v0.9.0
Features
-Added support for transparency / alpha values
-Added support for NO_COLOR environment variable
-Added new color pickers: Gnome/Wayland via gdbus, zenity, yad, and wcolor
==============
Version 2.54.3
==============
- #866 - Fix detection of gi-docgen (David King, Jan Alexander Steffens).
- Install the generated documentation in the correct place so that
Devhelp can find it (thanks to Jan Tojnar for pointing this out).
==============
Version 2.54.2
==============
- #823 - Fix regressions when computing element geometries.
- Add a --disable-gtk-doc option for the configure script, so people
can disable generating documentation for cross-compiling (Matt
Turner).
- MSVC: Support generating documentation, and passing introspection
paths (Chun-wei Fan)
==============
Version 2.54.1
==============
This release just has some build-time fixes.
- Fix oversight in the Minimum Supported Rust Version (MSRV) - this
release requires Rust 1.56 or later. This has been true since
librsvg 2.53.1, but it was not checked correctly. (Matt Turner)
- #859 - Make rst2man and gi-docgen optional. (Kleis Auke Wolthuizen)
- #856 - Fix documentation comments.
==============
Version 2.54.0
==============
This is a summary of the 2.53.x release notes; you can also read them
for more detail. Not many new features; we've been working on
infrastructure and documentation.
- Librsvg now supports SVG2 geometry properties for these elements:
rect, circle, ellipse, image, svg (Jeremias Ortega).
- #721 - Catch circular references when rendering patterns.
- The C API documentation now uses gi-docgen instead of gtk-doc.
Rsvg-convert's man page is now converted to reStructuredText instead
of troff.
- The "Recommendations for applications" chapter in the documentation
is much improved!
==============
Version 2.53.2
==============
- #851 - Output filled text as text for PDF; fixes regression due to
outputting all text as paths.
- Fix taller-than-wide proportional scaling and size limiting in
rsvg-convert.
- #772, #773, #774, #775, #776 - Implement SVG2 geometry properties
for these elements: rect, circle, ellipse, image, svg (Jeremias
Ortega).
- #450 - Fix potential unaligned accesses in surface iterators
(Michael Howell).
- Actually use GDK_PIXBUF_MODULEDIR when calling
gdk-pixbuf-query-loaders (Fabrice Fontaine).
- Windows build fixes (Chun-wei Fan).
- Add links to functions and types throughout the C API documentation.
==============
Version 2.53.1
==============
While it is not a user-visible change, Jordan Petridis has ported
librsvg's Continuous Integration (CI) infrastructure to use
Freedesktop CI Templates. This lets us test librsvg easily on
different environments. If you want your environment tested, now is
the time to add it!
- #599 - Fix incorrect text rendering when text has different scales
in the X/Y axes. This regressed after librsvg 2.52.5, when Pango
had to revert its fix for the same bug. Now librsvg renders all
text as paths, and does the scaling itself. Please file a bug if
you have evidence that this presents a performance problem for you.
- Update to the latest gtk-rs release (Bilal Elmoussaoui).
- Port to Freedesktop CI Templates (Jordan Petridis).

==============
Version 2.53.0
==============
This is the first release in the new development series. There are no
new features, just changes to how the documentation is built.
The man page for rsvg-convert is now generated from a reStructuredText
document, and the C API reference is generated using gi-docgen.
Please make sure you install python3-docutils (for rst2man) and
gi-docgen before compiling librsvg from a tarball.
- #755 - rsvg-convert's man page is now generated from reStructuredText.
- #827 - Move C API reference to gi-docgen.
- Test suite updates (Michael Howell).
- Link against bcrypt for Visual Studio builds (Martin Hertz).
Version 4.2-1
o Allow the vcov. argument in the call to one of the effect methods
to be a matrix or a function. Previously only a function was
permitted.
o Fixed bug in plot.eff() for multiline plots in which the x.var
argument is set explicitly (reported by Gerrit Eichner).
o Small improvements to docs.
Version 4.2-0
o Adding the use of the insight package to get formulas.
o Added Effect.glmmPQL() for fitting generalized linear mixed models
using the glmmPQL() function in the MASS package for penalized
quasi-likelihood estimation.
o Don't ignore lines lty sub-argument to plot.effpoly() (fixing a bug
reported by Laura Adamovicz).
o One-column matrix predictors trigger a warning and correction
(following problem reported by Carla Hendricks).
o Added regression tests for classes of model objects
supported. Tests must be enabled in the effects sources at
tests/regression-tests.R.
o Rewrite of defining effect method vignette.
o Minor changes to predictor effects gallery vignette.
Version 4.1-4
o Change class(x) == "y" to inherits(x, "y") in code.
Version 4.1-3
o Handle xlevels=n argument correctly in Effect() (fixing bug
reported by Gerrit Eichner).
o Add col argument to effectsTheme(), mostly to accommodate
colorblind-friendly palette (suggestion of Sercan Kahveci).
Version 4.1-2
o Effect methods for clm, clm2, and clmm models were not correctly
passing the estimated theshholds to polr for computing effects (error
reported by Stefan Th. Gries).
o Updated "Defining Effects Methods ..." vignette to reflect
revisions to Effect.clm, Effect.clm2 and Effect.clmm.
o Make sure that Effect() and plot() methods work correctly with
character and logical predictors (following bug report by Julian
Gaviria Lopez).

Fix: Implemented consistent behaviour between Pillow and Wand for out-of-bounds crop rectangles
Upstream changes:
WCSLIB version 7.11 (2022/04/26)
--------------------------------
* C library
- In tabini(), the default index array should contain a 1-relative
sequence: {1, 2,... N}. Previously it was 0-relative.
WCSLIB version 7.10 (2022/04/24)
--------------------------------
* C library
- In tabcpy(), collapse degenerate table index arrays if they are
collapsed in the source struct. Minor fix for output formatting
in tabprt().
- In the C test suite, added calls to wcstrim() in twcsfix to tidy
the structs before printing.
* Utilities
- The default option in wcsware now trims the wcsprm struct before
printing it. Use the '-p' option to print the untrimmed struct.
WCSLIB version 7.9 (2022/03/26)
-------------------------------
* C library
- In wcsset(), bug fix for identifying time coordinate axes.
Reported by Mihai Cara with patch.
WCSLIB version 7.8 (2022/03/25)
-------------------------------
* C library
- In wcssub(), bug fix for tabular coordinates that change axis
number, thus requiring tabprm::map to be updated. Reported by
Mihai Cara with patch.
Also in wcssub():
- check that all axes of a multi-dimensional table are extracted
together,
- fixed potential memory leaks for tabular coordinate axes when
an attempt to subimage non-separable axes fails,
- the error messages for non-separable coordinate systems are
generally more informative,
- subimage extraction by coordinate type now recognises time
coordinate axis types via WCSSUB_TIME.
- wcsset() now identifies time coordinate axes in wcsprm::types.
- Extended test program twcssub to test the above modifications.
* Installation
- Bug fix in the utils makefile for creating $(MANDIR)/man1.
Reported by Aleksander Kurek.
- Bug fix in the Fortran makefile for compiling and using 'tofits'.
Reported by Stefan Br▒ns.
* User manual
- Documentation generation moved to doxygen 1.9.3 (was 1.9.1).
WCSLIB version 7.7 (2021/07/12)
-------------------------------
* C library
- In disfree() and disset(), removed potential for double invokation
of free() on allocated memory. Reported by Cyril Richard.
- In wcsutil_fptr2str(), fixed a bug reported by Ralf Palsa (with fix)
that caused it to be overly enthusiastic in stripping leading zeroes
off addresses of function pointers.
- In wcspcx(), replaced variable length arrays with allocated memory
(portability issue). Reported by Mihai Cara with patch.
- Fixed buglets in wcsbth() and linsize() uncovered by gcc 11.1.0.
- Quelled inconsequential compiler warnings from gcc 11.1.0 concerning
wcsmix() (function prototype in wcs.h), wcstrim(), wcseulexe(),
wcsulex(), and wcsutrne().
- Defined _POSIX_C_SOURCE appropriately in tprj2.c and tspc.c to get
the function prototype etc. for nanosleep() from time.h.
* Fortran wrappers
- Quelled numerous inconsequential compiler warnings from gfortran
11.1.0.
- Fixed minor bugs uncovered by gfortran 11.1.0 in test programs tdis2
and ttab3.
* Utilities
- Moved 'tofits' from ./C/test/ into the utilities directory as it's
generally useful, and added usage (converted to man page).
Also made it a bit smarter in dealing with ISO/IEC 8859 and UTF-8
encoded byte streams, in particular translating non-breaking spaces
into ordinary spaces.
* Installation
- Two patches for configure.ac provided by Mos▒ Giordano:
1. makes it possible to build the Windows library using the MinGW
cross-compiler,
2. makes the soname of the MacOSX library consistent with other
Unix systems.
WCSLIB version 7.6 (2021/04/13)
-------------------------------
* C library
- Bug fix in tabs2x() triggered for 1-dimensional coordinate lookup
tables on axes > 1. Reported by Mihai Cara.
- In datfix(), don't return status 0 if no change was made (fix for
change made at release 7.4). Reported by Derek Homeier.
- New function wcspcx() in the wcsfix suite regularizes the linear
transformation component of a coordinate description to make it more
human-readable. It decomposes CDi_ja into PCi_ja and CDELTia in
such a way that CDELTia forms meaningful scaling parameters, often
leaving an orthogonal or near-orthogonal matrix. Optionally, it can
then permute rows of this matrix to unscramble axis permutations.
A test header may be generated from wcspcx.keyrec for input to
wcsware (not exercised as part of the standard test suite).
- New function wcstrim() frees memory allocated by wcsinit() for
arrays in a wcsprm struct that remain unused after the struct has
been set up.
- New functions wcssize(), auxsize(), tabsize(), linsize(), dissize(),
celsize(), prjsize(), spcsize(), and wcserr_size() compute the total
size of the relevant structs, including allocated memory.
- In the C test suite, inserted a brief pause in tprj2 and tspc, which
otherwise have now become a blur.
* Fortran wrappers
- Added wrappers for wcspcx(), wcstrim(), wcssize(), auxsize(),
tabsize(), linsize(), dissize(), celsize(), prjsize(), spcsize(),
and wcserr_size().
* Utilities
- Added -c, -cp, -C, and -Cp options to wcsware to apply wcspcx()
in a variety of ways, -m to apply wcstrim(), and -z to report the
total size of the wcsprm struct with a breakdown of the sizes of
its constituent structs.
- Fixed compiler warnings for sundazel (portability issue).
* Installation
- Upped the required version of Flex to 2.6.0 (was 2.5.9). Problems
with Flex 2.5.39 reported by Derek Homeier.
Also added '--disable-flex' as a new configure option to force the
use of the pre-generated Flex sources.
WCSLIB version 7.5 (2021/03/20)
-------------------------------
The C code in WCSLIB is moving piecemeal to the C99 standard. In fact,
various indispensible C99 constructs have been used in WCSLIB for many
years: the long long int data type (in fitshdr() only); stdint.h,
inttypes.h, and the use of PRI formatting control (in wcsprintf(), which
is widely used by the library); and the C99-extended library function
vsnprintf() (used by wcserr for a decade). Flex-generated C code also
uses C99 extensions, though with workarounds if they are not available.
Except in the header prologues, which are formatted in a special way for
generating the user manual, comments were changed en masse to C99 style
in release 7.3.1, and variable declarations in code that I have occasion
to modify will transition to the more general placement allowed by C99.
However, I have no plans to use any of the more esoteric features of
C99.
* C library
- New function, wcsccs(), changes the celestial coordinate system of a
wcsprm struct, for example, from equatorial to galactic coordinates.
The parameters that define the spherical coordinate transformation
must be provided. This allows WCSLIB to provide this functionality
without needing to know anything about specific celestial coordinate
systems, and has the advantage of making the routine completely
general. Requested by Mohammad Akhlaghi.
Modified test program twcsfix also to test wcsccs().
- Fixed a problem common to all of the Flex code (fitshdr, wcsbth,
wcspih, wcsulex, and wcsutrn) that made it thread-unsafe. Reported
by Cyril Richard.
Added a new test program, tpthreads, to test thread safety. It is
only used for code development, and not exercised as part of the
standard test suite.
- In fitshdr(), fixed a problem that potentially could arise on
systems where sizeof(long long int) is greater than 8 (64 bits).
* Fortran wrappers
- Match changes to the C library: added a wrapper for wcsccs(), and
modified twcsfix.f.
- Because null addresses cannot be passed to functions in Fortran,
wcssub_() now interprets *nsub == -1 && *axes == -1 as a signal to
do a deep copy of one wcsprm struct to another.
* Utilities
- New utility, sundazel, computes the local time of the Sun's passage
through the specified apparent longitude or latitude in a user-
defined coordinate system. It can also perform several other Solar
related calculations. (It is unrelated to FITS WCS, and does not
use WCSLIB.)
* Installation
- Added an 'uninstall' rule to the makefiles. Suggested by
Cyril Richard.
WCSLIB version 7.4 (2021/01/31)
-------------------------------
* C library
- In wcshdo(), fixed a bug introduced in release 5.9 that potentially
caused loss of numerical precision in the sprintf() formatting of
floating point keyvalues. This was triggered when a large range of
CRPIXja, PCi_ja, or CDELTia values (as three separate groups) were
formatted using an 'f' format descriptor, the range not being so
large that it would have forced wcshdo() to revert to 'E' format.
Reported by Mohammad Akhlaghi.
Also in wcshdo(), fixed a bug introduced in release 7.1 that caused
the coefficients of the TPD distortion function not to be written to
the header. TPD and Polynomial distortion function headers will now
always include the DPja.DOCORR keyword. Reported by Derek Homeier
with patch.
- In wcsset(), fixed a segv generated in attempting to report a non-
standard units string with wcserr message reporting disabled.
Reported by Mohammad Akhlaghi.
In wcsutrne(), allow 'Angstroms' and 'angstroms' as additional
synonyms for 'Angstrom'.
- In datfix(), ensure that 0 is returned if an informational message
is set in wcsprm::err. Consequent on feedback independently from
Mihai Cara and Bruce Merry.
Clarified that informational messages may be set in wcsprm::err
for returns of 0 from datfix(), obsfix(), unitfix(), and spcfix().
* User manual
- Added cautions about translating CDi_ja to PCi_ja plus CDELTia for
those historical distortion functions (TPV, TNX, ZPX) that expect to
operate on intermediate world coordinates, rather than intermediate
pixel coordinates. Consequent on feedback from Mohammad Akhlaghi.
- Documentation generation moved to doxygen 1.9.1 (was 1.8.19).
WCSLIB version 7.3.1 (2020/08/17)
---------------------------------
There are no functional changes in this release.
* C library
* Fortran wrappers
* PGSBOX
* Utilities
- Changed all C code, including within the flex sources, Fortran and
PGSBOX wrappers, and test suite, to use C99 style commenting (i.e.
using //), excluding the header prologues used to generate the user
manual.
* User manual
- Documentation generation moved to doxygen 1.8.19 (was 1.8.18).
WCSLIB version 7.3 (2020/06/03)
-------------------------------
* C library
- wcshdo() was writing MJD-OBS twice to the header, and MJD-BEG not
at all.
- In wcshdo(), if MJDREF assumes its default value, just write
MJDREF = 0 (not MJDREFI & MJDREFF), and omit writing DATEREF,
which, with a value of '1858-11-17', looks strange and is
potentially confusing. Reported by Thomas Robitaille.
If the fractional part of MJDREF is zero, then just write the
integer part as MJDREF (i.e. not as MJDREFI & MJDREFF).
- Bug fix in wcsfix() - it was writing error messages that referred
to DATE-REF and MJD-REF rather then DATEREF and MJDREF. Reported
by Mihai Cara.
- Under control of a new flag, WCSHDR_DATEREF, added the option to
wcspih() and wcsbth() to accept DATE-REF, MJD-REF, MJD-REFI,
MJD-REFF, JDREF, JD-REFI, and JD-REFF as synonyms for the standard
keywords, DATEREF, MJDREF, MJDREFI, MJDREFF, JDREF, JDREFI, and
JDREFF. The latter buck the pattern set by the other date keywords
({DATE,MJD}-{OBS,BEG,AVG,END}), thereby increasing the potential
for confusion and error.
* Fortran wrappers
- As compilers are becoming much stricter (gfortran 10), modified all
Fortran test programs to use the type-specific equivalents of the
various *PUT and *GET routines. Reported by Ole Streicher.
- For the fitshdr wrappers, added type-specific equivalents of
KEYGET: KEYGTI, KEYGTD, and KEYGTC.
* PGSBOX
- Modified pgtest to use the type-specific equivalents of WCSPUT.
* User manual
- In the section "WCSLIB Fortran wrappers", promoted use of the type-
specific equivalents of the various *PUT and *GET routines.
- In the section "FITS-WCS and related software", added ASCL and ADS
codes, where they exist, for all software packages mentioned.
- Documentation generation moved to doxygen 1.8.18 (was 1.8.17).

The main reason for this release was that KF5 had a backward incompatible
change. The minimum required version of Qt is bumped to 5.15.0 and that of
KF5 to 5.82.0. As a result, old distros can't be supported anymore.
Other changes:
- A workaround is added for the wrong style code of KisDoubleSliderSpinBox in
Krita ≥ 5.0.0.
- Options are added (to Kvantum Manager) for setting corner radii when blurring
translucent menus and tooltips with rounded corners. Usually, a value of 2 is
enough for preventing blur artifacts.
- 16px is given to the width of vertical spinbox buttons.
- Small fixes.
In this version, several internal changes have been included in order to
streamline and organize better the components and to change the
management of color. The changes are pretty deep and subtle, so a bug or
unexpected behaviour is always possible. You can use the 1.4.6 rollback
point in case of trouble, but be sure to report any bug.

CHANGES BETWEEN 2.11.1 and 2.12.0
I. IMPORTANT CHANGES
- FreeType now handles OT-SVG fonts, to be controlled with
`FT_CONFIG_OPTION_SVG` configuration macro. By default, it can
only load the 'SVG ' table of an OpenType font. However, by using
the `svg-hooks` property of the new 'ot-svg' module it is possible
to register an external SVG rendering engine. The FreeType demo
programs have been set up to use 'librsvg' as the rendering
library.
This work was Moazin Khatti's GSoC 2019 project.
II. MISCELLANEOUS
- The handling of fonts with an 'sbix' table has been improved.
- Corrected bitmap offsets.
- A new tag `FT_PARAM_TAG_IGNORE_SBIX` for `FT_Open_Face` makes
FreeType ignore an 'sbix' table in a font, allowing applications
to access the font's outline glyphs.
- `FT_FACE_FLAG_SBIX` and `FT_FACE_FLAG_SBIX_OVERLAY` together
with their corresponding preprocessor macros `FT_HAS_SBIX` and
`FT_HAS_SBIX_OVERLAY` enable applications to treat 'sbix' tables
as described in the OpenType specification.
- The internal 'zlib' code has been updated to be in sync with the
current 'zlib' version (1.2.11).
- The previously internal load flag `FT_LOAD_SBITS_ONLY` is now
public.
- Some minor improvements of the building systems, in particular
handling of the 'zlib' library (internal vs. external).
- Support for non-desktop Universal Windows Platform.
- Various other minor bug and documentation fixes.
- The `ftdump` demo program shows more information for Type1 fonts
if option `-n` is given.
- `ftgrid` can now display embedded bitmap strikes.
## Version 3.1.5 (April 11, 2022)

--------------
Released on **2022-02-05**
Release highlights
------------------
This is a bugfix release:
- Dependencies updated, fixing bitmap exports
- Graphic tablet pens erasors switch to the correct tool
- Fix lost styling of text converted to path
- Fix relative position of clones pasted to a new document
- Fix various crashes
Full release notes on https://wiki.inkscape.org/wiki/index.php/Release_notes/1.1.2
Changes to the previous version are relatively small (though we do need
this version to compile with the upcoming ocaml 4.14).
I've also added options to not compile the gtk and pango packages, which
means the package can be used on headless setups.
Significant changes relative to 2.1.2
Fixed a regression introduced by 2.0 beta1[7] whereby cjpeg compressed PGM input files into full-color JPEG images unless the -grayscale option was used.
cjpeg now automatically compresses GIF and 8-bit BMP input files into grayscale JPEG images if the input files contain only shades of gray.
The build system now enables the intrinsics implementation of the AArch64 (Arm 64-bit) Neon SIMD extensions by default when using GCC 12 or later.
Fixed a segfault that occurred while decompressing a 4:2:0 JPEG image using the merged (non-fancy) upsampling algorithms (that is, with cinfo.do_fancy_upsampling set to FALSE) along with jpeg_crop_scanline(). Specifically, the segfault occurred if the number of bytes remaining in the output buffer was less than the number of bytes required to represent one uncropped scanline of the output image. For that reason, the issue could only be reproduced using the libjpeg API, not using djpeg.
GEGL-0.4.36 2022-02-21
The primary addition in this release is SIMD dispatch, buffer access functions
get built for x86-64 v2 and v3 microarchitecture levels as well as ARM neon.
the same applies to core operations where we have .so bundles for the variants
as well as a generic build.
Operations:
The npd operation fixed with multiple threads.
Automatic LUT creation for conversions from <=24bpp of colorant componants,
SIMD builds for x86_64 micro-architecture levels and ARM neon, pre-defined
CIE Lab u8 and CIE Lab u16 formats. Fix bug of an unlocked non-locked mutex,
which started failing on some platforms.

==============
Version 2.52.6
==============
Backport a fix from the main branch:
- #599 - Fix incorrect text rendering when text has different scales
in the X/Y axes. This regressed after librsvg 2.52.5, when Pango
had to revert its fix for the same bug. Now librsvg renders all
text as paths, and does the scaling itself. Please file a bug if
you have evidence that this presents a performance problem for you.
==============
Version 2.52.5
==============
Just bugfixes this time:
- #812 - Fix mangled output in rsvg-convert when redirecting output to
a pipe on Windows (Michael Howell).
- #766 - When outputting to SVG, rsvg-convert now uses the
width/height units specified in the command line; it always used
pixels before (Daniel Petri Rocha).
- #814 - Fix incorrect top/left margins for SVG/PS/EPS/PDF output
(Daniel Petri Rocha).
- #599 - Fix incorrect placement of glyphs when text has non-uniform
scaling in the X/Y axes. This is not a librsvg bug, but is fixed by
Pango 1.49.3 and later. Hopefully Pango 1.48.11 will be released
soon with this fix as well. Note that this release of librsvg
cannot increase the minimum Pango version to 1.48.11 because it is
not released yet.
Miscellaneous:
- Updated crate dependencies: assert_cmd, cast, clap cssparser,
float-cmp, itertools, nalgebra, png, proptest, rctree, selectors,
system-deps.
==============
Version 2.52.4
==============
New features:
- #816 - Support the isolation property from the Compositing and
Blending Level 1 specification.
- Support Visual Studio 2022 (Chun-wei Fan).
Fixes:
- #818 - The opacity and mix-blend-mode properties were not being
applied when an element has a mask.
- Fix panic when an empty group has a pattern fill and filters.
- Fix the tests on Windows; the still only work when Fontconfig is
present (Chun-wei Fan).
- Work around a bug in the cairo-rs bindings in the test suite, that
only manifests itself in s/390x due to its calling convention. See
https://github.com/gtk-rs/gtk-rs-core/issues/335
==============
Version 2.52.3
==============
Bugfixes, mostly for text layout. Also, text links in PDF!
- #17 - Support text-decoration=overline.
- #249 - Basic support for the unicode-bidi property. Librsvg still
considers each tspan independently of others, which is incorrect, but
at least bidi-override works now for a single embedding level.
- #804 - Fix placement of tspan that changes the text direction.
- #805 - :lang() selector should now match lang attribute from an
element's parent. (Michael Howell)
- #806 - Fix the text-anchor property for right-to-left text.
- #807 - PDF now includes links inside text elements. (Michael Howell)
==============
Version 2.52.2
==============
Bugfixes and new features!
## New features
Thanks to Michael Howell, rsvg-convert now supports generating
multi-page PDFs in a sensible way.
With one SVG document per page, each page with the
SVG's natural size:
rsvg-convert --format=pdf -o out.pdf a.svg b.svg c.svg
With all pages sized as portrait US Letter, and each SVG scaled to fit
so that there is a 1in margin around each page:
rsvg-convert --format=pdf -o out.pdf \
--page-width=8.5in --page-height=11in \
--width=6.5in --height=8.5in --keep-aspect-ratio \
--top=1in --left=1in \
a.svg b.svg c.svg
Please see the man page for details.
- #738 - Support <a> elements inside <text>. Also, support the CSS :link
pseudo-class for matching against links. (Michael Howell)
- #649 - Support the CSS :lang() pseudo-class for matching against an
element's xml:lang attribute. (Michael Howell)
- #790 - Support the mask-type property from SVG2.
## Fixes
- #800 - Don't panic when a shorthand property is set to
inherit. (Michael Howell)
- #788 - Fix regression with the viewport size of interior <svg>
elements. (Michael Howell)
- #731 - Allow length units to be case-insensitive, per SVG2. (Kolja Lampe)
## Documentation
- There is now a FEATURES.md in the repository, where you can see all
the elements, attributes, and properties that librsvg supports. We
will be adding detail to this gradually.
- For developers, there is now devel-docs/adding-a-property.md with a
tutorial on how to add support for new CSS properties.
==============
Version 2.52.1
==============
This is a bugfix release; there are no new features this time.
## Changes:
- #791 - Fix ordering of tspan inside text elements for right-to-left
languages.
- #789 - Fix text-anchor positioning for right-to-left languages.
- #797 - Fix regression in computing sizes when an SVG has only one of
width/height and a viewBox. Thanks to Joshua Fogg for compiling a
list of test cases for this.
- #565 - Spec compliance - the writing-mode property applies only to
text elements, no to individual tspan elements.
- #794 - Fix build on big-endian platforms.
- Clarify documentation for the rsvg_handle_write() /
rsvg_handle_close() deprecated APIs.
==============
Version 2.52.0
==============
This is a big release! What follows is a summary from the 2.51.x
release notes; you can also read them for more detail.
The biggest user-visible change is that rsvg-convert has been ported
to Rust (Sven Neumann, Paolo Borelli), and it has new features!
## New features in rsvg-convert
### Support for physical units
rsvg-convert is now aware of physical units, and
fixes a bug where PDFs were created at the wrong size. Do you need to
render an SVG in a PDF file, scaled to 10x10 cm, placed at a certain
position of a landscape A4 page?
rsvg-convert --format=pdf \
--page-width=297mm --page-height=210mm \
--width=10cm --height=10cm --keep-aspect-ratio \
--top=5cm --left=8cm \
foo.svg > foo.pdf
Please see the rsvg-convert(1) man page for more details and plenty of
examples.
### Support for Accept-Language
Previously, librsvg picked up the user's language preferences through
environment variables like LANG and LC_MESSAGES. This is inconvenient
for applications that call rsvg-convert but don't want to synthesize a
LANG variable.
There is a new option in rsvg-convert so you can pass
--accept-language=<languages> formatted as an HTTP Accept-Language
header. This is used to specify which languages will be chosen from
elements with the "systemLanguage" attribute:
rsvg-convert --accept-language=es-MX,en foo.svg
That command will select Mexican Spanish and English from suitable SVG
elements. Please see the man page for details.
### Miscellaneous
rsvg-convert's default DPI is now 96, to better match W3C
standards. It was 90 before for historical reasons. We can change
this back to 90 if it breaks too many scripts. You can use the
options "--dpi-x=90 --dpi-y=90" to restore the old behavior.
rsvg-convert no longer supports the "xml" or "recording" output
formats. These are useful only for debugging Cairo, not for general
usage.
## SVG2/CSS3 features
The following features are supported now. Madds H, John Ledbetter,
worked on these features.
- transform property from SVG2; previously librsvg only supported the
transform attribute from SVG1.1, which has different syntax.
- context-fill and context-stroke for <marker> and <use> elements.
- markers now support orient="auto-start-reverse".
- paint-order for text elements.
- "auto" values for the width and height attributes of the <image>,
<rect>, and <svg> elements.
- All the <filter-function> types from the Filter Effects Module Level
1 specification: blur(), brightness(), contrast(), drop-shadow(),
grayscale(), hue-rotate(), invert(), opacity(), sepia(), saturate().
- The filter property now supports chains of uri() filters or
<filter-function> shortcuts.
- Support CSS selectors for attribute matching, like rect[attr^="prefix"]
## New APIs
See the HTML documentation for details:
- rsvg_handle_get_intrinsic_size_in_pixels()
- rsvg_major_version / rsvg_minor_version / rsvg_micro_version
variables - used to obtain the librsvg version from languages other
than C, since they do not have access to the C macros like
LIBRSVG_MAJOR_VERSION.
## Deprecations
The following APIs are deprecated but still available:
- rsvg_handle_render_cairo() - use rsvg_handle_render_document() instead.
- rsvg_handle_render_cairo_sub() - use rsvg_handle_render_layer() or
rsvg_handle_render_element() depending on what you want to do.
Please see the "Migrating from old APIs" chapter in the HTML
documentation for details.
## News for developers
If you want to run the librsvg test suite easily, there are now Docker
scripts to do so. Please see the tools/docker/README.md file for
details. (Madds H)
There is no leftover C code in the library; all of the implementation
and the publically-visible symbols are defined in the Rust code. The
remaining .h files are all public and do not reflect any .c
code. (Sven Neumann)
The test suite is now ported to Rust. The only remaining tests in C
are for the C API itself (tests/api.c). With the test suite in
Rust, the tests are automatically run in parallel across CPU cores,
making test runs much faster. (Sven Neumann, Dunja Lalic)
"cargo build", "cargo test" now work without running autotools first,
so you can in general develop librsvg as a normal Rust project.
The HTML documentation has new chapters; you may find interesting
things there!
## News for distributors
There is a new list of librsvg releases with security fixes in
SECURITY.md. That file also contains security-related information
on librsvg's dependencies.
The Minimum Supported Rust Version (MSRV) is now Rust 1.52.
## Special thanks
Paolo Borelli and Sven Neumann did a lot of painstaking work to finish
porting the library and rsvg-convert to Rust.
Sven Neumann and Dunja Lalic ported the test suite to Rust, making it
much faster.
Dunja Lalic rewrote the Continuous Integration infrastructure, making
it MUCH faster.
Madds H did their Outreachy internship for librsvg and implemented a
bunch of useful SVG2/CSS3 features.
John Ledbetter methodically went through all the <filter-function>
shortcuts and implemented them for SVG2.
Ismael Luceno has been cleaning up our autotools scripts.
Andre Klapper has been wrangling numerous bug reports from Wikimedia
as usual.
Chun-wei Fan, Abraham Toriz, Christian Hergert, Ignacio Casal Quinteiro
have been keeping the Windows and MacOS builds working.
==============
Version 2.51.4
==============
- #618 - SVG2: Implement context-fill and context-stroke for markers
(Madds H).
- #727 - SVG2: Implement paint-order for text elements (Madds H).
- #747 - SVG2: Support width="auto" and height="auto" for the image element.
- Fix the Windows build (Chun-wei Fan).
- The tools/docker directory now has scripts that developers can use
to test librsvg on containers for various Linux distributions.
- Gtk-rs dependency is updated to 0.14.0 (Bilal Elmoussaoui, Chun-wei Fan).
- #758 - Panic when rendering with masks or opacity to a non-image surface.
- #757 - Fix 32-bit builds.
==============
Version 2.51.3
==============
The big news is that rsvg-convert is now aware of physical units, and
fixes a bug where PDFs were created at the wrong size. Do you need to
render an SVG in a PDF file, scaled to 10x10 cm, placed at a certain
position of a landscape A4 page?
rsvg-convert --format=pdf \
--page-width=297mm --page-height=210mm \
--width=10cm --height=10cm --keep-aspect-ratio \
--top=5cm --left=8cm \
foo.svg > foo.pdf
Please see the rsvg-convert(1) man page for more details and plenty of
examples.
SVG2 features:
Markers now implement orient="auto-start-reverse". The work on
markers is by Madds H., who is doing their Outreachy internship for
librsvg.
All the <filter-function> types in SVG2 are now supported, thanks to
John Ledbetter.
- The Minimum Supported Rust Version (MSRV) is now Rust 1.52. This
takes care of CVE-2021-28878 in the Rust standard library.
- #514 - rsvg-convert is now aware of physical units.
- #484 - Markers can now have orient="auto-start-reverse" per SVG2
(Madds H - Outreachy internship).
- #711 - Implement the drop-shadow() filter function (John Ledbetter).
- #713 - Implement the hue-rotate() filter function (John Ledbetter).
- #677 - rsvg-convert, do not clip the rightmost/bottomost pixels of
an image with partial pixel coverage.
- Partial fix for #668 - Render small caps for fonts that support the
"smcp" OpenType feature. Librsvg and Pango are not yet able to
synthesize small caps for fonts that do not support them, but for
those that do, they should work fine now.
- #566 - Restrict which elements can appear inside a clipPath, to be
spec compliant.
- #746 - Possible cairo_save() without cairo_restore() in render_layer().
- Various updates to the developer's documentation.
==============
Version 2.51.2
==============
This release fixes an important bug about text spacing. The bug fix
requires an update to at least Pango 1.44. Sorry for the increased
requirements!
Librsvg now supports most of the filter function shortcuts in SVG2;
see below.
Previously, librsvg picked up the user's language preferences through
environment variables like LANG and LC_MESSAGES. This is inconvenient
for applications that call rsvg-convert but don't want to synthesize a
LANG variable.
There is a new option in rsvg-convert so you can pass
--accept-language=<languages> formatted as an HTTP Accept-Language
header. This is used to specify which languages will be chosen from
elements with the "systemLanguage" attribute:
rsvg-convert --accept-language=es-MX,en foo.svg
That command will select Mexican Spanish and English from suitable SVG
elements. Please see the man page for details.
- The Minimum Supported Rust Version (MSRV) is now Rust 1.51.
- Librsvg now requires at least Pango 1.44.
- #730 - Incorrect text spacing when the transform is not 1:1. You
can see this when a small font-size is scaled up due to a
transform. It is less visible for a large font-size scaled down.
- #709#710#712 714 #715#716#717 - The "filter" attribute now
accepts lists of "<filter-function>" per SVG2. There is support for
blur(), contrast(), grayscale(), invert(), opacity(), saturate(),
sepia() (John Ledbetter).
- #356 - Add --accept-language option to rsvg-convert.
- #704 - Fix circle/ellipse in paths when they are made out of a
single Arc command.
- #691 - Don't allow number lists with unbounded lengths in
tableValues attributes, for feComponentTransfer and
feConvolveMatrix (Madds H).
- #718 - Negative rx/ry in rect element should be ignored.
- #687 - Reduce memory pressure when rendering text.
- Fix build on 32-bit ARM (Lovell Fuller).
- Update the Rust crate dependencies (Bastien Orivel).
- Refactoring parsers (Paolo Borelli).
- There is a new list of librsvg releases with security fixes in
SECURITY.md. That file also contains security-related information
on librsvg's dependencies.
Special thanks to John Ledbetter for carefully implementing each of
the new shortcuts for filter functions in SVG2.
==============
Version 2.51.1
==============
- The Minimum Supported Rust Version is now 1.48.
- rsvg-convert should fully work on Windows again (Abraham Toriz).
- rsvg-convert's SVG output format uses pixel units instead of points again.

==============
Version 2.51.0
==============
There are many changes in this development release! This experimental
release is meant for early testing, with the understanding that some
things may be broken, especially since we have large changes to the
way librsvg's artifacts are built.
The biggest user-visible change is that rsvg-convert has been ported
to Rust (Sven Neumann, Paolo Borelli).
Please file bugs at https://gitlab.gnome.org/GNOME/librsvg/-/issues/new
if these changes break your scripts; they are experimental for the
2.51.x development series:
- #646 - rsvg-convert's default DPI is now 96, to better match W3C
standards. It was 90 before for historical reasons. We can change
this back to 90 if it breaks too many scripts. You can use the
options "--dpi-x=90 --dpi-y=90" to restore the old behavior.
- rsvg-convert's --export-id (-i) option should now have more useful
behavior. This extracts a particular element from the SVG document
and renders it scaled to the size specified by the --width/--height
arguments, or to the pixel size of the element as if it had no
transformations applied.
- rsvg-convert no longer supports the "xml" or "recording" output
formats. These are useful only for debugging Cairo, not for general
usage.
Known missing features, which should be restored for the stable release:
- rsvg-convert does not allow stdin/stdout streams on Windows; this is
being tracked in issue #676.
The following are changes related to porting to Rust; they are not
necessarily user-visible, but important for developers of the library:
- There is no leftover C code in the library; all of the
implementation and the publically-visible symbols are defined in the
Rust code. The remaining .h files are all public and do not reflect
any .c code. (Sven Neumann)
- The test suite is now ported to Rust. The only remaining tests in C
are for the C API itself (tests/api.c). With the test suite in
Rust, the tests are automatically run in parallel across CPU cores,
making test runs much faster. (Sven Neumann, Dunja Lalic)
- "cargo build", "cargo test" should now work without running
autotools first.
- The C API is now implemented on top of the public Rust API, without
special hooks into the library's internals.
The following APIs are deprecated but still available:
- rsvg_handle_render_cairo() - use rsvg_handle_render_document() instead.
- rsvg_handle_render_cairo_sub() - use rsvg_handle_render_layer() or
rsvg_handle_render_element() depending on what you want to do.
- These deprecations are because the new APIs conform with the web
world's view of how SVGs should be positioned and scaled in
surrounding content. Whereas the old APIs were about rendering SVGs
to whatever current transformation matrix a Cairo context may
contain, the new APIs take a rectangular viewport and librsvg
automatically scales the SVG document to fit in it. The "natural
sizing" that was implicit in the deprecated APIs is now explicitly
documented, and available through the new API
rsvg_handle_get_intrinsic_size_in_pixels().
New APIs:
- rsvg_handle_get_intrinsic_size_in_pixels() converts an SVG
document's intrinsic dimensions to pixels, i.e. transforms the SVG
document's "width" and "height" attributes to CSS pixels.
New features and bug fixes:
- #615: SVG2: Support a chain of uri() filters in the "filter" property
(John Ledbetter, Sven Neumann).
- #483: Support CSS selectors for attribute matching, like rect[attr^="prefix"]
- #554: Fixed the geometry_for_layer() APIs to not ignore the passed viewport.
- Fixed CSS "import" so it allows only files from the same base directory
(Lars Schmertmann).
- #642 - Fix dx/dy offsets in nested <tspan> elements.
- #601 - Compute correct bounds for objects with stroke-width=0.
- Slight speed improvements in the RGBA premultiplication code (Sven Neumann).
- #623 - The pkg-config files (*.pc) do not define the 'svgz_supported' and
'css_supported' variables anymore. These variables were hardcoded
to 'true' and unchanged since 2011.
- #624 - The source repository no longer produces a librsvg-uninstalled.pc file.
- Fix the MacOS build (Christian Hergert, Ignacio Casal Quinteiro).
- Deal with missing pkg-config (Ismael Luceno).
- For cross-compilation, check for target-specific prefixed tools like
rustc/cargo (Heiko Becker).
Changes in the Rust API:
- #597 - The LoadingError and RenderingError enums have changed, and
are now marked #[non_exhaustive]. They will probably change again
to hide details of error variants before we make librsvg available
as a crate on crates.io.
Special thanks for this release:
- Dunja Lalic for revamping the CI infrastructure and making our CI
runs much, much faster - !398.
- Sven Neumann, Dunja Lalic for porting the test suite to Rust.
- Sven Neumann, Paolo Borelli for porting rsvg-convert to Rust and
unraveling all the little historical details that were embedded in
it.
- Paolo Borelli for constant refactoring.
This package provides a simple interface for building .dot graph files, for
input into the dot and graphviz tools. It includes a monadic interface for
building graphs.
picat - picture cat
Picat converts images to sixel graphics, and outputs them to stdout. The tool
achieves high quality output by making use of the
libimagequant, https://pngquant.org/lib/ library for converting RGBA images
to the sixel palette.
The release tarballs contain prebuilt files (specifically documentation).
If using the tagged snapshots, the documentation needs to be built which
requires tcl as a build tool. If built with option -tcl, the package fails
to build.

ZXing-C++ ("zebra crossing") is an open-source, multi-format 1D/2D
barcode image processing library implemented in C++.
It was originally ported from the Java ZXing Library but has been
developed further and now includes many improvements in terms of
quality and performance. It can both read and write barcodes in a
number of formats.
If audio/pulseaudio is already installed, the build fails by pulse/pulseaudio.h not found error.
The pulseaudio option is disabled by default.
Bump PKGREVISION by dependency change.

Mon, 03 Jan 2022 11:29:03 +0100 Daniel Friesel <derf+feh@finalrewind.org>
* Release v3.8
* Add button ID "0" to cursor bindings. This pseudo-button is triggered
whenever feh observes a cursor movement. It does not have a default
binding.
* Support hexadecimal IDs in --window-id
* Disable --auto-rotate in feh builds compiled with Imlib2 1.7.5 or later.
Imlib2 1.7.5 introduces transparent EXIF-based image orientation
adjustment, so --auto-rotate is no longer needed (and would cause
mis-orientation of images, as Imlib2 has already adjusted the
orientation).

Provide C++ versions for public macros with casts.
Many FreeType clients use C++. However `g++ -Wold-style-cast` warns for
macros with C-style casts even for system header files; this also affects
directories included with `-isystem`. While this could be seen as a problem
with g++, the problem is more a philosophical one: Over the time, C and C++
diverged more and more, and some features of C are no longer the 'right'
solution in C++.
* include/freetype/config/public-macros.h (FT_STATIC_CAST,
FT_REINTERPRET_CAST): New macros.

[sfnt] Reduce footprint if WOFF and WOFF2 support is not needed.
Based on a patch from metarutaiga (MR !106). The gist of this commit is
that it doesn't make sense to support WOFF without compression (which would
be only possible in WOFF 1.0 anyway).
* src/sfnt/sfobjs.c (sfnt_open_font): Guard WOFF code with
`FT_CONFIG_OPTION_USE_ZLIB` block.
Guard WOFF2 code with `FT_CONFIG_OPTION_USE_BROTLI` block.
* src/sfnt/sfwoff.c, src/sfnt/sfwoff.h: Guard files with
`FT_CONFIG_OPTION_USE_ZLIB` blocks, not parts of the code.
* src/sfnt/sfwoff2.c, src/sfnt/sfwoff2.h, src/sfnt/woff2tags.c,

[dlg] Define DLG_STATIC explicitly.
DLG_STATIC is intended to disable Windows DLL linking attributes.
It does not hurt to define it explicitly when we wrap DLG code.
This fixes tons of LNK4286 and C4273 warnings from MSVC if we

[mm] Tolerate missing Blend dictionary entries
In a Multiple Master font, the Blend dictionary must contain valid
Private, FontInfo, and FontBBox. The current code will error if any of
these are present and invalid, but will not error and will provide
uninitialized data if the Blend dictionary exists but does not contain
one of these entries. This change reverts to the older behavior of
treating any missing entries as containing all zero data and not
returning an error.
In the future it may be best to keep track of when these are actually
initialized and error if they are not.
* src/type1/t1load.c (t1_allocate_blend): Zero initiailize.

[mm] Delay setting blend weight and design position.
Previously the `blend->weight_vector`, `blend->default_weight_vector`,
and `blend->design_pos` were set early to allocated but uninitialized
memory under the assumption that the memory would eventually be
initialized. However, it is possible that some of the required
keywords may not actually be present, leaving the memory uninitialized.
This is different from a present but invalid table, which would produce
an error.

vector and design positions.

[cff] Commit vstore data and regions on allocation.
The vstore->regionCount and vstore->dataCount were read directly
from the data. However, vstore->varRegionList and vstore->varData
would still contain uninitialized entries with uninitialized

to clean up.

[sfnt] Delay setting gasp ranges and count until computed.
Previously, the gasp.numRanges was set and gasp.gaspRanges was
allocated and assigned before a possible early exit if the frame could
not be entered. It is also possible that the gaspRanges allocation
could fail but the numRanges still be set to non-zero. In such cases
an error would be returned, but the face would have a gasp in an
inconsistent state which may still be accessed.

2021-10-20 Ben Wagner <bungeman@chromium.org>
[sfnt] Delay setting names and langTags until computed.
Previously, the table->names and table->langTags fields were created
pointing to uninitialized memory and an early exit could happen if the

autogen.sh: Only copy submodules if building from a git branch.
`autogen.sh` fails if building from a standard source tarball. Firstly, git
expects to be called in a git repository, then `copy_submodule_files`
blindly attempts to copy files.
Debian, Ubuntu, Linux Mint, and other derivatives all run `autogen.sh`
before compiling to regenerate build files.
This patch ensures that various git commands are only called and 'dlg' files
are only copied if `autogen.sh` is called from a git repository.

[smooth] Reduce shift in multiply-shift optimization.
* src/smooth/ftgrays.c (FT_UDIVPREP, FT_UDIV): Reduce shift.
Smaller shifts that keep the division operands of FT_UDIVPREP within
32 bits result in slightly faster divisions, which is noticeable in
the overall performance. The loss of precision is tolerable until the
divisors (the components dx and dy) approach 32 - PIXEL_BITS. With
PIXEL_BITS = 8, this corresponds to 65,000 pixels or the bitmap size
that we refuse to render anyway.

[truetype] New function to skip the randomization tag.
* src/truetype/ttobjs.c (tt_skip_pdffont_random_tag):
New function to skip the randomization tag in the names of the

to keep from mistaking "DLC" in the randomization tag as a
tricky font name. See discussion in:
https://lists.nongnu.org/archive/html/freetype-devel/2021-02/msg00002.html

Fix invalid memory access in `bsdf` rasterizer.
Do not generate SDF from bitmap if the `FT_GLYPH_OWN_BITMAP` flag is not
set. In some cases the bitmap buffer is freed but still points to a valid
address; to handle those cases check the flag before accessing the memory.
* src/sdf/ftsdfrend.c (ft_bsdf_render): Handle the above case.
Also, return an error message if the bitmap's rows/pitch is invalid,
otherwise `slot->buffer` might be assigned to some invalid memory location.

Plus, move the outline back to original state after rasterization and not if
any error occurs.

[autofit] Split `afwrtsys.h`.
The header file `afwrtsys.h` has two distinct functions: to include the
required writing system headers and also to generate code for each writing
system. At each current use site only one or the other is used, with
various macro trickery selecting one or the other. Split this header into
`afws-decl.h` for the required writing system declarations and `afws-iter.h`
for iterating over the writing systems to generate code.
The motivation for this change is that the Visual C++ compiler treats the
standard include guard idiom like `#pragma once` 'if no non-comment code or
preprocessor directive comes before or after the standard form of the
idiom'. It appears to check this after macro expansion, so if
`WRITING_SYSTEM` expands to empty the bottom of `afwrtsys.h` is empty and
looks like the standard include guard idiom which is treated like `#pragma
once`, so subsequent inclusion of `afwrtsys.h` is elided.
Fixes#1075.

* src/smooth/ftgrays.c: Fix compilation if `FT_LONG64` is undefined.
The code assumed that if `__SSE2__` is defined, then 64-bit integer
types are available. This is not the case apparently for certain
multilib compiler targets like 'x86_32.x86' used by Gentoo.
This patch fixes the issue by disabling the special code path when
64-bit integer types are not available.
Fixes#1071.

[tests] Allow arbitrary build directories.
* tests/issue-1063/main.c (main): I am building with a build
directory that is not directly inside the source tree, so the path
`../tests/data/As.I.Lay.Dying.ttf` does not resolve to the test
input file. This change passes the test data directory as an
environment variable to allow arbitrary build directories.
* tests/meson.build: Updated.

should.

[smooth] Minor fixes.
* src/smooth/ftgrays.c (gray_render_conic): Move variable and
structure declarations to beginning of function. Inspite of C99
compliance we still do this for the sake of backward compatibility.
This also avoids a shadowing declaration of `count`.
(gray_convert_glyph_inner): Fix typo.
2021-07-15 Ben Wagner <bungeman@chromium.org>
* src/smooth/ftgrays.c: Guard inclusion of `emmintrin.h`.
Guard inclusion of `emmintrin.h` with `#ifdef __SSE2__`. The gcc
version of this header, `xmmintrin.h`, and `mmintrin.h` check that
the appropriate defines are set before defining anything (are
internally guarded). However, the clang versions of these includes
are not internally guarded. As a result of this, externally guard
the inclusion of these headers.

[smooth] Implement Bézier quadratic arc flattening with DDA.
Benchmarking shows that this provides a very slighty performance
boost when rendering fonts with lots of quadratic Bézier arcs,
compared to the recursive arc splitting, but only when SSE2 is
available, or on 64-bit CPUs.
On a 2017 Core i5-7300U CPU on Linux/x86_64:
ftbench -p -s10 -t5 -cb DroidSansFallbackFull.ttf
Before: 4.033 us/op (best of 5 runs for all numbers)
After: 3.876 us/op
ftbench -p -s60 -t5 -cb DroidSansFallbackFull.ttf
Before: 13.467 us/op
After: 13.385 us/op
* src/smooth/ftgrays.c (gray_render_conic): New implementation
based on DDA and optionally SSE2.

[smooth] Minor speedup to smooth rasterizer.
This speeds up the smooth rasterizer by avoiding conditional
branches in the hot path.
- Define a fixed 'null cell', which will be pointed to whenever the
current cell is outside of the current target region. This avoids
a `ras.cell != NULL` check in the `FT_INTEGRATE` macro.
- Also use the null cell as a sentinel at the end of all `ycells`
linked-lists, by setting its x coordinate to `INT_MAX`. This
avoids a `if (!cell)` check in `gray_set_cell` as well.
- Slightly change the worker struct fields to perform a little less
operations during rendering.
Example results (on a 2013 Corei5-3337U CPU)
out/ftbench -p -s10 -t5 -bc DroidSansFallbackFull.ttf

Support architectures where `long` is smaller than pointers.
I am currently trying to compile FreeType for CHERI-extended ISAs
(CHERI-RISC-V and Arm's Morello), but I am getting compiler warnings
from the `FT_UINT_TO_POINTER` macro. When compiling with the CHERI
Clang compiler, not using `uinptr_t` for casts between integers an
pointers results in the following `-Werror` build failures:
```
In file included from .../src/truetype/truetype.c:22:
.../src/truetype/ttgload.c:1925:22: error:
cast from provenance-free integer type to pointer type will
give pointer that can not be dereferenced
[-Werror,-Wcheri-capability-misuse]
node->data = FT_UINT_TO_POINTER( glyph_index );
^
.../include/freetype/internal/compiler-macros.h:79:34: note:
expanded from macro 'FT_UINT_TO_POINTER'
```
* include/freetype/internal/compiler-macros.h (FT_UINT_TO_POINTER):
The ISO C standard compliant fix for this would be to use
`uintptr_t` from `stdint.h`, but I am not sure if this is supported
by the minimum compiler version. Therefore, use the
compiler-defined `__UINTPTR_TYPE__` macro (supported in GCC 4.6+ and
Clang since about 3.0) before checking for `_WIN64` and falling back
to `unsigned long`.
2021-07-13 Oleg Oshmyan <chortos@inbox.lv>
[base] Fix `FT_Open_Face`'s handling of user-supplied streams.
This was already true (though undocumented) most of the time, but
not if `FT_NEW` inside `FT_Stream_New` failed or if the
`FT_OPEN_XXX` flags were bad.
Normally, `FT_Open_Face` calls `FT_Stream_New`, which returns the
user-supplied stream unchanged, and in case of any subsequent error
in `FT_Open_Face`, the stream is closed via `FT_Stream_Free`.
Up to now, however, `FT_Stream_New` allocates a new stream even if
it is already given one by the user. If this allocation fails, the
user-supplied stream is not returned to `FT_Open_Face` and never
closed. Moreover, the user cannot detect this situation: all they
see is that `FT_Open_Face` returns `FT_Err_Out_Of_Memory`, but that
can also happen after a different allocation fails within the main
body of `FT_Open_Face`, when the user's stream has already been
closed by `FT_Open_Face`. It is plausible that the user stream's
`close` method frees memory allocated for the stream object itself,
so the user cannot defensively free it upon `FT_Open_Face` failure
lest it ends up doubly freed. All in all, this ends up leaking the
memory/resources used by user's stream.
Furthermore, `FT_Stream_New` simply returns an error if the
`FT_OPEN_XXX` flags are unsupported, which can mean either an
invalid combination of flags or a perfectly innocent
`FT_OPEN_STREAM` on a FreeType build that lacks stream support.
With this patch, the user-supplied stream is closed even in these
cases, so the user can be sure that if `FT_Open_Face` failed, the
stream is definitely closed.
* src/base/ftobjs.c (FT_Stream_New): Don't allocate a buffer
unnecessarily.
Move error-handling code to make the control flow more obvious.
Close user-supplied stream if the flags are unsupported.
`FT_Stream_Open` always sets `pathname.pointer`, so remove the
redundant (re)assignment. None of the `FT_Stream_Open...` functions
uses `stream->memory`, so keep just one assignment at the end,
shared among all possible control flow paths.
('Unsupported flags' that may need a stream closure can be either an
invalid combination of multiple `FT_OPEN_XXX` mode flags or a clean
`FT_OPEN_STREAM` flag on a FreeType build that lacks stream
support.)
2021-07-13 Oleg Oshmyan <chortos@inbox.lv>
[base] Reject combinations of incompatible `FT_OPEN_XXX` flags.
The three modes are mutually exclusive, and the documentation of the
`FT_OPEN_XXX` constants notes this. However, there was no check to
validate this in the code, and the documentation on `FT_Open_Args`
claimed that the corresponding bits were checked in a well-defined
order, implying it was valid (if useless) to specify more than one.
Ironically, this documented order did not agree with the actual
code, so it could not be relied upon; hopefully, nobody did this and
nobody will be hurt by the new validation.
Even if multiple mode bits were allowed, they could cause memory
leaks: if both `FT_OPEN_STREAM` and `stream` are set along with
either `FT_OPEN_MEMORY` or `FT_OPEN_PATHNAME`, then `FT_Stream_New`
allocated a new stream but `FT_Open_Face` marked it as an 'external'
stream, so the stream object was never released.
* src/base/ftobjs.c (FT_Stream_New): Reject incompatible
`FT_OPEN_XXX` flags.
2021-07-12 Alex Richardson <Alexander.Richardson@cl.cam.ac.uk>
* meson.build: Fix build for other UNIX systems (e.g., FreeBSD).
Without this change the build of `unix/ftsystem.c` fails because the
`ftconfig.h` header that defines macros such as `HAVE_UNISTD_H` and
`HAVE_FCNTL_H` is only being generated for Linux, macOS, and Cygwin
systems:
```
.../builds/unix/ftsystem.c:258:32: error:
use of undeclared identifier 'O_RDONLY'
file = open( filepathname, O_RDONLY );
```
Instead of hardcoding a list of operating systems for this check,
update the logic that decides whether to build the file and set a
boolean flag that can be checked instead.

Remove experimental auto-hinting 'warp' mode.
This feature was always experimental, and probably never worked
properly. This patch completely removes it from the source code,

* src/truetype/ttgxvar.c (tt_set_mm_blend): Test `coords`.
It is undefined behavior to pass `NULL` to `memcpy`. `coords' is
passed to `memcpy` but `TT_Get_MM_Blend` and `TT_Get_Var_Design`
explictly call `tt_set_mm_blend` with `coords` as `NULL`. In
addition, `TT_Set_MM_Blend` has a similar possible issue.

[sfnt] Handle fonts without layer list in 'COLR' v1.
'COLR' v1 fonts do not necessarily need to have a layer list; for
this reason, 'fontTools' recently started generating fonts in a way
that drops the layer list if there are no layers in it. This
results in the layer list offset becoming zero, which FreeType
treated as an invalid table. Fix that and handle the case for layer
list offset being 0. This slightly changes how we need to calculate
the starting offset for paints.
* src/sfnt/ttcolr.c (tt_face_load_colr): Handle case of layer list
offset being zero without outright rejecting table.

2021-06-28 Dominik Röttsches <drott@chromium.org>
[sfnt] Improve paint limit checks
Paint tables can appear before the `base_glyphs_v1` offset if the
font is produced with the layer list before the base glyph list. In
this case paint tables can occur after the layer list but before the
base glyph list. Checks in the 'COLR' v1 code were rejecting fonts
with this layout. Improve these checks by calculating a minimum
offset after which paint tables can occur and use that in safety
checks.
* src/sfnt/ttcolr.c (Colr, tt_face_load_colr): Declare
`paint_start_v1` and calculate that as the minimum of the end of
layer list and base glyph list.
(get_child_table_pointer, read_paint, tt_face_get_paint_layers):
Use that in safety checks.

[base] Add trace level to logging output.
Some practical debugging work has shown that displaying level X of

an example, we now get output like
```

[sdf] Use 8 bits for final SDF output instead of 16bits.
Since 8-bits is enough to represent SDF data we no longer require
16-bits for this purpose. Also, we now normalize the output data
to use the entire 8-bit range efficiently. For example: if we use
3.5 format with a spread of 1 we basically only use the starting
5-bits. By normalizing we can use the entire 8-bit range.

[gzip] Use exact type for `ft_gzip_alloc` and `ft_gzip_free`.
While a function pointer may be cast to another function pointer
type, it is required to cast the function pointer back to the
original function pointer type before calling it. If a parameter is
a pointer the exact pointer type is required. Using a pointer to a
different underlying type is technically undefined behavior. The
wrapper functions `ft_gzip_alloc` and `ft_gzip_free` took
`FT_Memory` (a `FT_MemoryRec_*`) instead of `voidpf` (`void*`), so
when gzip calls these callbacks through `alloc_func` or `free_func`
it invokes undefined behavior. On most platforms this works out as
expected, but newer undefined behavior detectors and targets like
wasm can detect this and will produce an error.
* src/gzip/ftgzip.c (ft_gzip_alloc, ft_gzip_free): Update signatures
to exactly match `alloc_func` and `free_func`, respectively.
Internally, cast the `void*` opaque pointer to `FT_Memory`.

[smooth] Faster bitmap sweeping.
Selecting the fill rule or checking the direct mode each time we call
`gray_hline' is sub-optimal. This effectively splits the direct mode
into a separate code path while inlining `gray_hline' and saving 5-7%
of rendering time.

[truetype] Prevent glyph program state from persisting.
`FDEF` instructions are specified as allowed only in 'prep' or
'fpgm'. FreeType has attempted to prevent their use in the glyph
program, but they were still allowed in glyph programs if defined in
a function defined in 'prep' or 'fpgm' and called from the glyph
program.
Similarly, `IDEF` instructions are specified not to be able to
modify any existing instruction. FreeType has attempted to prevent
their use in the glyph program, but they can still be used like
`FDEF`.
This change stores the initial bytecode range type and disallows the
use of `FDEF` and `IDEF` while running the glyph program.
Most other state is copied from the `TT_Size` into the execution
context. However, it is possible for a glyph program to use `WS` to
write to the storage area or `WCVTP`, `WCVTF`, and `DELTAC[123]` to
write to the control value table.
Allowing any change to the global state from the glyph program is
problematic as the outlines of any given glyph may change based on
the order the glyphs are loaded or even how many times they are
loaded. There exist fonts that write to the storage area or the
control value table in the glyph program, so their use should not be
an error.
Possible solutions to using these in the glyph program are
* ignore the writes;
* value-level copy on write, discard modified values when finished;
* array-level copy on write, discard the copy when finished;
* array-level copy up-front.
Ignoring the writes may break otherwise good uses. A full copy
up-front was implemented, but was quite heavy as even well behaved
fonts required a full copy and the memory management that goes along
with it. Value-level copy on write could use less memory but
requires a great deal more record keeping and complexity. This
change implements array-level copy on write. If any attempt is made
to write to the control value table or the storage area when the
initial bytecode range was in a glyph program, the relevant array
will be copied to a designated storage area and the copy used for
the rest of the glyph program's execution.

[sfnt] Fix memory leak in png loading.
Reported as
https://bugs.chromium.org/p/chromium/issues/detail?id=1182552
Memory is allocated and the pointer assigned to `rows` inside a
'setjmp' scope. This memory must be freed outside the 'setjmp'
scope after a 'longjmp'. Since `rows` is a local and modified
inside the 'setjmp' scope it must be marked volatile or it will have
an indeterminate value after the 'longjmp'.
* src/sfnt/pngshim.c (Load_SBit_Png): Fix memory leak of `rows`.
2021-03-16 Christopher Degawa <ccom@randomderp.com>
* CMakeLists.txt: Don't limit generation of 'pkg-config' file to UNIX.
mingw-w64 uses the 'pkg-config' files but does not set UNIX.

2021-03-09 Alexei Podtelezhnikov <apodtele@gmail.com>
* src/smooth/ftgrays.c (gray_render_line): Rearrange conditionals.
These produce faster or more optimizable code.

[woff2] Fix memory leak.
Reported as
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=28148
* src/sfnt/sfwoff2.c (woff2_open_font): Reject fonts that have
multiple tables with the same tag. While not explicitly forbidden
in the OpenType specification, it is implicitly forbidden by
describing a binary search algorithm for tables that only works
reliably if table tags are unique.
2021-02-22 Werner Lemberg <wl@gnu.org>
* CMakeLists.txt: Update location of `LICENSE.TXT`.
Fixes#1035.
2021-02-19 Werner Lemberg <wl@gnu.org>
* builds/unix/ax_pthread.m4: Update from 'autoconf-archive'.
A bunch of fixes were added recently to its git repository.
2021-02-17 Werner Lemberg <wl@gnu.org>
[unix] Updates for autoconf 2.71.
This fixes warnings reported by autoupdate.
* builds/unix/ax_pthread.m4: Replace `as_echo` with `AS_ECHO`.
* builds/unix/configure.raw: Remove obsolete `AC_HEADER_STDC`.
Don't escape back quotes in messages for `AC_MSG_WARN`.
2021-02-16 Werner Lemberg <wl@gnu.org>
* builds/toplevel.mk: Fix previous commit.
<top_level>: Use `TOP_DIR` in `wildcard` function.
(check_out_submodule, copy_submodule): Move down to come after
definition of `all` rule.
Call `mkdir` conditionally.
2021-02-16 Werner Lemberg <wl@gnu.org>
* builds/toplevel.mk: Use rules for handling 'dlg'.
Suggested by Alexei.
(check_out_submodule, copy_submodule): New targets.
<top-level>: Replace calls to `shell` with rules.
2021-02-16 Werner Lemberg <wl@gnu.org>
* builds/toplevel.mk: Avoid side effects of `shell`.
We use a dummy variable to catch its output. Otherwise the `make`
program is going to interpret the return value of `shell`; this can
cause obscure warning or error messages or even be harmful.
2021-02-16 Werner Lemberg <wl@gnu.org>
Move 'dlg' submodule to `subprojects` directory.
This is for future changes with Meson, which doesn't allow a
different name for its `subprojects` directory. Having both a
`submodules` and a `subprojects` directory is confusing.
* .gitmodules, autogen.sh (copy_submodule_files, DLG_INC_DIR,
DLG_SRC_DIR): Updated.
* builds/toplevel.mk (<top-level>, do-dist),
builds/windows/vc2010/script.bat: Updated.
* src/tools/no-copyright: Updated.
2021-02-16 Dominik Röttsches <drott@chromium.org>
[sfnt] Update paint format values to support non-variable paints.
* freetype.h (FT_PaintFormat): Update paint format identifiers after
a specification change. The specification was updated to have
sibling formats, variable and non-variable variants for each.
Reflect that here.
* sfnt/ttcolr.c (read_paint): Remove parsing of variable indices as
the non-variable formats no longer have them.
2021-02-15 Daniel E <daniel.engberg.lists@pyret.net>
* CMakeLists.txt: Improve 'bz2' support.
Not all distributions such as FreeBSD provide a `.pc` file for
'(lib)bz2' so follow autotools and add it to `Libs.private` instead.
2021-02-13 Werner Lemberg <wl@gnu.org>
* src/tools/update-copyright-year: Fix single-year entry handling.
The fix from 2021-01-17 didn't cover the case where the year to be
updated is identical to the current year.
2021-02-13 Werner Lemberg <wl@gnu.org>
Add new function `FT_Get_Transform`.
See
https://github.com/harfbuzz/harfbuzz/issues/2428
for some reasons to introduce this function.
* include/freetype/freetype.h, src/base/ftobjs.c (FT_Get_Transform):
Implement it.
2021-02-12 Alexei Podtelezhnikov <apodtele@gmail.com>
Decorate `qsort` callbacks with `cdecl`.
* include/freetype/internal/compiler-macros.h (FT_COMPARE_DEF):
Add new macro.

src/psaux/afmparse.c, src/psnames/psmodule.c, src/type1/t1afm.c,
src/sfnt/sfwoff.c, src/sfnt/sfwoff2.c: Update `qsort` callbacks.
Fixes#1026 when compiling FreeType with an unusual calling
convention while the C library function `qsort` still expects
`cdecl`.
2021-02-10 Dominik Röttsches <drott@chromium.org>
[sfnt] Implement 'COLR' v1 sweep gradients.
* freetype.h (FT_PaintSweepGradient): Add `FT_PaintSweepGradient` to
represent a 'COLR' v1 sweep gradient.
Update format.
(FT_PaintFormat): Update shifted paint formats.
Sync with spec.
* sfnt/ttcolr.c (read_paint): Logic to parse sweep gradients.
Fix struct access in radial gradient implementation.
2021-02-09 Dominik Röttsches <drott@chromium.org>
[sfnt] Provide optional root transform for 'COLR' v1 glyph graph.
* include/freetype/freetype.h (FT_Get_Color_Glyph_Paint):
Additional function argument `root_transform` to control whether
root transform should be returned.
(FT_OpaquePaint): Additional tracking field to denote whether
root transform is to be returned.
* include/freetype/internal/sfnt.h
(TT_Get_Color_Glyph_Paint_Func): Propagate additional argument.
* src/base/ftobjs.c (FT_Get_Color_Glyph_Paint): Ditto.
* src/sfnt/ttcolr.c (tt_face_get_colr_glyph_paint): Return root
transform reflecting the size and tranform configured on
`FT_Face`.
(read_paint): Initialize and track status of insert_root_transform
flag.
2021-02-09 Xavier Claessens <xavier.claessens@collabora.com>
* meson.build: s/freetype2_dep/freetype_dep/.
Many projects (e.g., fontconfig, cairo) hardcode the `freetype_dep`
variable name to use FreeType as subproject because that was the
variable name in Centricular's Meson port of FreeType. While they
should stop hardcoding that variable name, it does not cost us
anything to keep using that name to ease transition.
2021-02-09 Xavier Claessens <xavier.claessens@collabora.com>
[meson] Fix handling of HarfBuzz library.
* meson.build (harfbuzz_dep): Do not fall back to HarfBuzz by
default.
Otherwise it causes a dependency cycle:
cairo => fontconfig => freetype2 => harfbuzz => cairo
Meson will still fall back to HarfBuzz subprojects if the `harfbuzz`
option is set to `enabled` instead of `auto` and a
`subprojects/harfbuzz.wrap` file is present. In that case it is the
responsibility of the main project to set the proper options on each
subproject to break the dependency cycle.
Fixes: #1028.
2021-02-09 Xavier Claessens <xavier.claessens@collabora.com>
[meson] Fix dependency lookup and generate `ftconfig.h`.
- zlib: If not found on the system, meson can build it as a
subproject. We thus never use the (outdated) zlib support that
comes with FreeType. Doing so has the additional advantage that
the zlib code can be shared with other projects like GLib if both
are subprojects of an application.
- harfbuzz: Build as a subproject if not found on the system.
- 'QUESTION: What if the compiler doesn't support `-D` but uses `/D`
instead as on Windows?' Answer: Meson translate arguments for us.
- visibility: Replace self-made code with meson-specific solution.
* meson.build (ft2_defines): Rewrite logic to set and handle it.
(process_header_command): New variable, previously called
`ftoption_command`.
(ftoption_command, ftconfig_command): New variables.
(zlib_option): Removed.
(zlib_dep): New variable.
(ft2_deps): Updated.
(harfbuzz_dep): Updated.
(ftconfig_h_in, ftconfig_h): New variables.
(ft2_sources): Updated.
(ft2_lib): Updated, handle visibility.
(summary): Updted.
* meson_options.txt (zlib): Updated.
2021-02-09 Xavier Claessens <xavier.claessens@collabora.com>
* meson.build: Fix resource compilation on Windows.
This is copied from GStreamer's meson port of FreeType.
(ft2_sources): Add both debug and resource file (the latter for
Windows only).
(ft2_debug_src): Removed.
2021-02-09 Xavier Claessens <xavier.claessens@collabora.com>
* meson.build: s/ft2_libtool_version/ft2_pkgconfig_version/.
(freetype2_dep): Use it.
`ft2_libtool_version` would be the shared library version, not the
one we should use in file `freetype2.pc`.
2021-02-09 Xavier Claessens <xavier.claessens@collabora.com>
* meson.build: Use `meson.override_dependency`.
This is a new meson mechanism to avoid other projects to hard-code
the `freetype2_dep` variable name in their build definition. It
also ensures that meson does not mix system and subproject versions
of FreeType inside of the same project.
Also remove outdated TODO because `declare_dependency` was already
there.
2021-02-09 Xavier Claessens <xavier.claessens@collabora.com>
* meson.build (bzip2_dep): Simplify.
We remove `static:false` from `find_library('bz2')`.
I don't know whether the previous code was a workaround for an old
meson bug, but at least with version >=0.55.0 (which FreeType uses)
it picks the shared library when both are available.
File `freetype2.pc` still contains the full path to file `libbz2.so`
instead of `-lbz2` – that we need to do this is a meson bug even
present in the current version (0.57.0).
2021-02-09 Xavier Claessens <xavier.claessens@collabora.com>
* meson.build: Set project version.
2021-02-04 Werner Lemberg <wl@gnu.org>
[base] Fix Netpbm tracing message.
* src/base/ftobjs.c (FT_Render_Glyph_Internal): Don't emit Netpbm
warning if there is nothing to output.
2021-02-04 Werner Lemberg <wl@gnu.org>
* src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`.
This ensures good logging output, with all lines having a proper
prefix (if requested).
This is a continuation of a similar patch from 2020-12-02, which
missed some locations.

Always provide logging API.
It's easier to have stubs if FT_DEBUG_LOGGING is undefined than to
modify `ftexport.sym` conditionally.
Problem reported by Alexei.
* src/base/ftdebug.c: Include `ftlogging.h`.
(FT_Trace_Set_Level, FT_Trace_Set_Default_Level, FT_Set_Log_Handler,
FT_Set_Default_Log_Handler) [!FT_DEBUG_LOGGING]: Provide stubs.
2021-01-31 Werner Lemberg <wl@gnu.org>

tt_face_get_colorline_stops, tt_face_get_paint): Additional checks
for whether colr table is present. Prevents crashes when these
methods are called on non-COLR fonts.
2021-01-13 Dominik Röttsches <drott@chromium.org>
Add config option to test for 'COLR' v1 support in headers.
* include/freetype/config/ftoption.h (TT_SUPPORT_COLRV1): New macro
so that clients can test whether the FreeType checkout that they are
building against supports the 'COLR' v1 API. This is intended to be
a temporary solution until 'COLR' v1 support is released in a
FreeType version and such a check can be made by using the version
number instead.
2020-12-16 Dominik Röttsches <drott@chromium.org>

check for existence of `FT_Face`, check arguments and delegate calls
for the respective 'COLR' v1 API to the SFNT driver.
2020-12-16 Dominik Röttsches <drott@chromium.org>

certain format, which contains the detailed information stored in a
paint of the respective format.
(read_paint): New function to provide the format specific parsing
and to populate the data members of each specific `FT_COLR_Paint`
subtype.

renderer's glyph format check before adding and removing them. The
'bsdf' renderer will have a format `FT_GLYPH_FORMAT_BITMAP`.

2020-12-18 Tatsuyuki Ishi <ishitatsuyuki@gmail.com>
[autofit] Fix double division in stem darkening.
The old code used to divide the darkening amount by em_ratio twice,
leading to unnecessarily bold stems on certain fonts with higher
units per em (e.g. Inter). This patch fixes it.
The return value of af_loader_compute_darkening was also changed to
use 16.16 fixed point to get rid of a redundant truncation operation.
This should slightly improve the precision, although it's still
bottlenecked by the emboldening function, which uses 26.6 fixed point.
* src/autofit/afloader.[ch]
(af_loader_compute_darkening): Return FT_Fixed.
(af_loader_embolden_glyph_in_slot): Revise calculations.
2020-12-17 Alexei Podtelezhnikov <apodtele@gmail.com>

[truetype] Fix incremental metrics (#59503).
* src/truetype/ttgload.c (tt_get_metrics, load_truetype_glyph):
Previously, the code would populate the phantom points before
calling the `get_glyph_metrics` callback. For formats like PCL XL
format 1, class 2 downloaded fonts (where metrics are removed from
the TTF header), this causes problems when the hinting program uses
the phantom points (misplaced and distorted glyphs) due to the
metrics being unset (all zeros).
(tt_get_metrics_incr_overrides): Renamed to...
(tt_get_metrics_incremental): ... this. Updated caller
* include/freetype/ftincrem.h: Update the documentation to make it
clearer that `get_glyph_metrics` is to retrieve metrics from a
non-standard source, but *not* for the purpose of imposing custom
metrics.
2020-12-14 Werner Lemberg <wl@gnu.org>

Overview of Changes from GIMP 2.10.28 to GIMP 2.10.30
=====================================================
Core:
- Do not follow subpixel font rendering choice from system settings
for text layer rendering. These systems are useful for GUI
rendering on a screen of a specific type and pixel order. Yet when
rendering an image which can be zoomed in or out, showed on various
screens or even printed, subpixel font rendering doesn't make sense.
- Rewrite the core selection drawing logics so that it works on macOS
Big Sur and over. This is a backport (adapted to GTK+2) of the fix
brought in GIMP 2.99.8 for Wayland and macOS.
- Ignore MakerNote metadata tag at export and only store the tags that
go in it, hence avoiding partial invalid metadata.
- Color picking from Colors dockable can now use the Freedesktop
portal.
- On Windows, move from GetICMProfile() to WcsGetDefaultColorProfile()
because the former is broken in Windows 11.
Plug-ins:
- metadata-viewer: improve how XMP tags with multiple values are
handled and shown (now each value on a separate line for better
readability).
- metadata-editor:
* XMP array tags of type BAG and SEQ are now on separate lines.
* Comparing XMP tags with equivalent IPTC tags with multiple values,
each value is compared individually, instead of comparing the list
as a whole.
- Many robustness improvements and other fixes to the metadata
plug-ins.
- AVIF: prefer AOM encoder for export.
- PSD:
* Skip sanity check for mask of rendered layers as some layer mask
have invalid dimensions in such cases. They will now be loaded
correctly.
* Fixed loading of CMYK PSD files without alpha.
* Fixed loading of CMYK images without layers.
* Fixed loading of merged image of a 16 bit per channel RGBA PSD
file with the alpha channel opaque.
- PBM: large file export now always works and does not depend anymore
on the platform's long int size.
- Screenshot:
* GNOME shell implementation dropped because the D-Bus API has been
restricted to core components for security reasons, thus our
plug-in was failing.
* KDE portal moved as last fallback after the X implementation
(when running on X) and Freedesktop portal, because KDE is also
starting to block API calls for security reasons.
Installer:
- Extension .avif now associated to GIMP.
- Drop codepage conversion, use UTF-8 for language files.
Build:
- macOS support officially bumped to macOS 10.12 (Sierra). We would
usually try to avoid doing this within a stable release but the
conditions (lack of contributors) is such that it is hard to avoid.
Changelog:
GEGL-0.4.34 2021-12-19
----------------------
Operations:
~~~~~~~~~~~
magick-load: use g_spawn_async instead of system to run the image magick
convert fallback - preventing shell expansion on non-escaped/filtered
paths in constructed commandline.
ripple: avoid a possible division by zero.
Build:
~~~~~~
Explicit dependency specification in meson for generated CL files.
ctx has been moved to be part of gegl-common.so nearer to the operations
using it avoiding polluting the GEGL library symbol table with the ctx
symbols.
pkgsrc updates:
---------------
* Add missing files in PLIST when nls option is enable.
* Remove lines in PLIST.Linux that are already in PLIST (thanks to
pkglint).
* Bump revision.
