Update to 2.4.6, No answer from maintainer.
CHANGES BETWEEN 2.4.5 and 2.4.6
I. IMPORTANT BUG FIXES
- For TrueType based fonts, the ascender and descender values were
incorrect sometimes (off by a pixel if the ppem value was not a
multiple of 5). Depending on the use you might now experience
a different layout; the change should result in better, more
consistent line spacing.
- Fix CVE-2011-0226 which causes a vulnerability while handling
Type 1 fonts.
- BDF fonts containing glyphs with negative values for ENCODING
were incorrectly rejected. This bug has been introduced in
FreeType version 2.2.0.
- David Bevan contributed a major revision of the FreeType stroker
code:
. The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
. A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has
been introduced to support PostScript and PDF miter joins.
. FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced ches has
been fixed.
II. MISCELLANEOUS
- SFNT bitmap fonts which contain an outline glyph for `.notdef'
only no longer set the FT_FACE_FLAG_SCALABLE flag.
CHANGES BETWEEN 2.4.4 and 2.4.5
I. IMPORTANT BUG FIXES
- A rendering regression for second-order B#zier curves has been
fixed, introduced in 2.4.3.
II. IMPORTANT CHANGES
- If autohinting is not explicitly disabled, FreeType now uses
the autohinter if a TrueType based font doesn't contain native
hints.
- The load flag FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH has been made
redundant and is simply ignored; this means that FreeType now
ignores the global advance width value in TrueType fonts.
III. MISCELLANEOUS
- `FT_Sfnt_Table_Info' can now return the number of SFNT tables of
a font.
- Support for PCF files compressed with bzip2 has been contributed
by Joel Klinghed. To make this work, the OS must provide a
bzip2 library.
- Bradley Grainger contributed project and solution files in
Visual Studio 2010 format.
- Again some fixes to better handle broken fonts.
Upstream changes:
* Changes in cropping code:
o cropping is now works for Fuji files (instead of crash)
o bad pixels map and dark frame subtraction is turned off if cropping enable
o for technical reasons, coordinates of top-left corner of crop box are
rounded to multiple of 4 for Fuji files.
* ./configure stuff fixes:
o install static libraries only when --enable-static is set
o compiled samples are dynamically linked if shared library not disabled.
* OpenMP enabled for Visual Studio 2008 SP1+, but not for RTM
Changes:
- quoted translate command string
- quote of tmpfname for coping with spaces in filenames
- added -a option
- changed handling of hiresBB (now rounded to hiresprecision, by default 0.5pt)
- added %%BeginData %%EndData as indicators for Binary Section
- added new option -b (treat as binary) to prevent filtering CR/LF stuff
- fixed help/usage formatting output

Changelog:
2011.07.01 v.11.07
+ The main retouch functions can now be used in parallel
(i.e. multiple edit dialogs can be active at the same time).
+ The last position of the main window and most dialog windows is saved
and restored within a session and across sessions.
+ New function Match Colors: take a spot color sample from two images.
The colors of the 2nd image are changed to match the first.
+ New function Revise RGB: select up to 9 control pixels on an image and
adjust their RGB values. All image pixels are adjusted to match, using
weights based on distances from the control pixels. Use this function
to make complex color adjustments that vary across the image.
+ Brightness Ramp was revised to handle RGB colors. This is an alternative
method to remove a color caste that varies across an image or image area.
+ Tools > Show RGB: EV and OD units are output in addition to RGB values.
Up to five points are shown, updated live as the image is edited.
+ The Brightness/Color curves now have a range of +/-2 EV (F-stops) and
the step-adjust buttons ([+++] etc.) are calibrated in 0.1 EV steps.
Steps 1/3 this size can also be used. Use this function in conjunction
with Show RGB to make calibrated color adjustments.
+ Numeric feedback was added to the sliders in retouch edit functions.
+ Missing gallery thumbnails are generated 2-3x faster (on multi-core
processors) using multiple threads working ahead of need (usually).
+ Clone (new window) now has two variants: share desktop 50/50 or open
a new window of the same size, slightly offset for visibility.
+ Open File now has two variants: use the same window or open a new
window in a parallel instance of Fotoxx.
+ New toolbar button: save file as a new version (immediate, no dialog).
The current image and its edit history remain unchanged.
+ Save-As menu and toolbar: new checkbox option to switch the current
file to the saved file. The edit trail (undo/redo) is also retained.
+ New command line parameters:
-prev open the last file viewed in the previous session.
-recent start with a gallery of recent files (most recent at top).
(-prev used to be default but this is no longer the case).
+ If the [undo] or [redo] button is pressed with the shift-key, they
become "undo all" and "redo all". This makes it easier to compare
an image having multiple edits with the original image.
+ Select Area [Unfinish] button: put a finished area back in edit mode.
+ Pixel Edit was moved from the Art menu to the Retouch menu.
+ Hourglass cursor was replaced with a BUSY sign at bottom of the window.
+ Toolbar help is a topic help like F1. Menu help opens the user guide.
+ Bugfix: warp functions were infrequently putting artifacts in the image.
+ Bugfix: Edit Collections could crash if adds and deletes were mixed.
+ Bugfix: Select Area Edge Calculation: if killed by user, the area was
left in a half finished condition.
2011.06.13 v.11.06.2
Bugfix: Ubuntu 11.04 32-bit: libtiff.so was moved to a really different
location: /usr/lib/i386-linux-gnu/libtiff.so. This caused a misleading
diagnostic when building from source, so the check and diagnostic was
simply eliminated. The packages are not affected.
New extensions:
* GL_AMD_blend_minmax_factor
* GL_AMD_sample_positions
* GL_EXT_x11_sync_object
* GL_NV_texture_multisample
* GL_NV_video_capture
* GLX_NV_video_capture
* WGL_NV_DX_interop
* WGL_NV_video_capture
Bug fixes:
* Define GLEW_NO_GLU for no glu dependency.
* mx suffix for GLEW MX libraries, build both libraries by default.
* Cygwin build improvements
* Soname of GLEWmx shared libraries
* Query GL extension string only once
* GLX_OML_sync_control no longer requires C99
* glDraw*InstancedARB moved from GL_ARB_draw_instanced to
GL_ARB_instanced_arrays
* glFramebufferTextureLayerEXT moved from GL_EXT_geometry_shader4 to
GL_EXT_texture_array
* Fixes for BSD build

xsane-0.994 -> 0.995:
---------------------
- changed layout of copy setup, removed border around all setup tabs
- changed layout of xsane main window
- xsane-front-gtk.c: xsane_browse_filename_callback: xsane.cms_function_option_menu is only updated when xsane.enable_color_management is active
- xsane-save.c: write_smtp_header(): it is allowed to specify multiple mail receivers in a comma separated list now
- xsane-save.c: write_smtp_header(): MAIL FROM and RCPT TO use syntax "<user@domain.org>" instead of "user@domain.org" now
- xsane-front-gtk.c: created xsane_progress_bar_set_fraction which uses the gtk2
functions when available and which only updates the progress_bar every 2.5 percent
what speeds up several functions - especially saving file routines -
xsane*.c: replaced all gtk_progress_bar_update() by xsane_progress_bar_set_fraction()
- xsane-back-gtk.c: in function xsane_back_gtk_value_update()
replaced comparison for SANE_FIX values
if (new_val != val)
by
if (abs(new_val - val) > 1)

---------------------
- removed bug when deleting medium types: removed free() command, added realloc()
- xsane_viewer.c: reduced maximum viewer size form gdk_screen_width/gdk_screen_height to
gdk_screen_width-1/gdk_screen_height-1
- xsane-save.c: PDF: ICC object 4+5 are initialized with offset 0
- xsane-save.c: PDF: objects with offset 0 are makred free (f) in xref table
xsane-0.996 -> 0.997:
---------------------
- removed SANE_CAP_ALWAYS_SETTABLE (not SANE1)
- added test for (opt->size == 0) for SANE_TYPE_STRING in xsane.c

xsane-0.997 -> 0.998:
---------------------
- removed bug saving image as 16 bit png:
until now all low byte data has been a copy of the high byte data,

Version 1.5.3beta11 [June 11, 2011]
Fixed png_handle_sCAL which is broken in 1.5; added sCAL to pngtest.png
Revised documentation about png_set_user_limits() to say that it also affects
png writing.
Revised handling of png_set_user_limits() so that it can increase the
limit beyond the PNG_USER_WIDTH|HEIGHT_MAX; previously it could only
reduce it.
Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is
wrong (high by one) 25% of the time. Dividing by 257 with rounding is
wrong in 128 out of 65536 cases. Getting the right answer all the time
without division is easy.
Added "_SUPPORTED" to the PNG_WRITE_CUSTOMIZE_ZTXT_COMPRESSION macro.
Added projects/owatcom, an IDE project for OpenWatcom to replace
scripts/makefile.watcom. This project works with OpenWatcom 1.9. The
IDE autogenerates appropriate makefiles (libpng.mk) for batch processing.
The project is configurable, unlike the Visual Studio project, so long
as the developer has an awk.
Changed png_set_gAMA to limit the gamma value range so that the inverse
of the stored value cannot overflow the fixed point representation,
and changed other things OpenWatcom warns about.
Revised pngvalid.c to test PNG_ALPHA_MODE_SUPPORTED correctly. This allows
pngvalid to build when ALPHA_MODE is not supported, which is required if
it is to build on libpng 1.4.
Removed string/memory macros that are no longer used and are not
necessarily fully supportable, particularly png_strncpy and png_snprintf.
Added log option to pngvalid.c and attempted to improve gamma messages.
Version 1.5.3 [omitted]
People found the presence of a beta release following an rc release
to be confusing; therefore we bump the version to libpng-1.5.4beta01
and there will be no libpng-1.5.3 release.
Version 1.5.4beta01 [June 14, 2011]
Made it possible to undefine PNG_READ_16_TO_8_ACCURATE_SCALE_SUPPORTED
to get the same (inaccurate) output as libpng-1.5.2 and earlier.
Moved definitions of PNG_HAVE_IHDR, PNG_AFTER_IDAT, and PNG_HAVE_PLTE
outside of an unknown-chunk block in png.h because they are also
needed for other uses.
Version 1.5.4beta02 [June 14, 2011]
Fixed and clarified LEGACY 16-to-8 scaling code.
Added png_set_chop_16() API, to match inaccurate results from previous
libpng versions.
Removed the ACCURATE and LEGACY options (they are no longer useable)
Use the old scaling method for background if png_set_chop_16() was
called.
Made png_set_chop_16() API removeable by disabling PNG_CHOP_16_TO_8_SUPPORTED
Version 1.5.4beta03 [June 15, 2011]
Fixed a problem in png_do_expand_palette() exposed by optimization in
1.5.3beta06
Also removed a spurious and confusing "trans" member ("trans") from png_info.
The palette expand optimization prevented expansion to an intermediate RGBA
form if tRNS was present but alpha was marked to be stripped; this exposed
a check for tRNS in png_do_expand_palette() which is inconsistent with the
code elsewhere in libpng.
Correction to the expand_16 code; removed extra instance of
png_set_scale_16_to_8 from pngpriv.h
Version 1.5.4beta04 [June 16, 2011]
Added a missing "#ifdef PNG_READ_BACKGROUND_SUPPORTED/#endif" in pngrtran.c
Added PNG_TRANSFORM_CHOP_16 to the high-level read transforms.
Made PNG_READ_16_TO_8_ACCURATE_SCALE configurable again. If this is
not enabled, png_set_strip_16() and png_do_scale_16_to_8() aren't built.
Revised contrib/visupng, gregbook, and pngminim to demonstrate chop_16_to_8
Version 1.5.4beta05 [June 16, 2011]
Renamed png_set_strip_16() to png_set_scale_16() and renamed
png_set_chop_16() to png_set_strip(16) in an attempt to minimize the
behavior changes between libpng14 and libpng15.
Version 1.5.4beta06 [June 18, 2011]
Fixed new bug that was causing both strip_16 and scale_16 to be applied.
Version 1.5.4beta07 [June 19, 2011]
Fixed pngvalid, simplified macros, added checking for 0 in sCAL.
The ACCURATE scale macro is no longer defined in 1.5 - call the
png_scale_16_to_8 API. Made sure that PNG_READ_16_TO_8 is still defined
if the png_strip_16_to_8 API is present. png_check_fp_number now
maintains some state so that positive, negative and zero values are
identified. sCAL uses these to be strictly spec conformant.
Version 1.5.4beta08 [June 23, 2011]
Fixed pngvalid if ACCURATE_SCALE is defined.
Updated scripts/pnglibconf.h.prebuilt.
Version 1.5.4rc01 [June 30, 2011]
Define PNG_ALLOCATED to "restrict" only if MSC_VER >= 1400.
Version 1.5.4 [July 7, 2011]
no changes.
