GEGL-0.4.14 2019-03-xx
Core
New Scratch allocator for short lived buffers.
Removed unneeded buffer copies in some processing code paths in
GeglNode and GeglProcessor.
Add gegl_babl_variant API for getting variations on an existin
pixel-format/encoding.
Expose gegl_node_is_graph()
GeglBuffer
Compression of tile data.
Handle dynamically changing swap dir.
Improvements to mipmap damage propagation.
Fixes to threading race conditions.
Low-level tile handling more adapted to buffers creating from existing
linear data.
New iterator API is now the default, GEGL_BUFFER_ITERATOR2_API is no
longer needed.
CMYK/grayscale handling for scaled blits, code paths in samplers,
serialization.
New default tile-cache size, 50% of RAM.
Initialize the first OpenCL device with IMAGE support.
Added gegl_parallell_ from gimp_parallell_ API to distribute processing
for multiple cores.
Operations
crop, added aux-pad - if connected the incoming bounding box determines
the crop size.
Input-format specific processing for performance in watershed-transform
and invert ops. CMYK handling in jpg-load/save, tiff-load/save,
gaussian-blur, opacity, most composing and blending operations, text,
vector-stroke, path, and transform operations.
Improved or fixed mipmap preview rendering of emboss, linear-gradient
and radial-gradient.
Better ui strings/range/defaults for: distort/waves and dropshadow,
value-propagate.
gaussian-blur: fix mistake in implementation of IIR Young blur 1d,
which caused non circular halos.
New operation: pdf-load with build dependency on poppler-glib
Added offset properties to pixelize filter.
new ops in workshop: voroni diagram, Grey Color Removal, spyrograph.
Handle mipmap rendering for linear-gradient and radial-gradient.
UI
The existing microraptor-gui (immediate mode touch UI+CSS with cairo)
image viewer that can be built as part of the gegl binary has been
revisted, a graph/property editor has been added, and migration/
extension to lua has begun for parts of the code.
many parts of the UI is of exploratory proof of concept/alpha
Warning quality but released since it is part of the GEGL repository
and useful development tools both for creating and testing new
GEGL operations as well as GEGL itself.
Some screenshots showing some the process towards the state and
capabilties of the UI in this release can be seen at https://

To build with this UI the following dependencies also need to be
satisifed, for now this is not intended to be packaged by distributions
yet.
libluajit-dev
lua-lgi (debian package name) upstream:
mmm https://github.com/hodefoting/mmm
mrg https://github.com/hodefoting/mrg
Features: folder view resolution independent UI touch oriented

performance and capabilty issues in GEGL efficient (though not
sandboxed) thumbnailing embedded simple commandline graph editor
zoomable automatic, consistent graph layout autogenerated

This release depends on the new features of babl-0.1.62 which has the
following change summary for the last release:
Continuous integration with gitlab. Initial CMYK spaces with lcms2
based ICC support, much room for optimization. Improved custom space
support for palette formats. scRGB space, works like sRGB but always
with linear TRCs. Model introspection API permitting low overhead
checks whether a format/model is RGB, CMYK type of alpha and similar.

GEGL-0.4.4 2018-06-02
Core
Point filters with need for format conversion of input are now

Trim tile-cache when shrinking. Add reading locks to tiles further
improving concurrent access tolerance of GeglBuffer.
Operations

unsharp-mask: add rename standard-deviation and scale properties to
Radius and Amount, add Threshold property. recursive-transform now
supports applying multiple transformations simultanously. Fix integer

Changelog:
GEGL-0.4.0 2018-04-26
GEGL 0.4.x is a stable release series of GEGL to have a stable API
and ABI to go with GIMP-2.10. When the need arises to break API or
ABI compatibility the 0.4.x series will get its own branch and
unstable API experiments and development, 0.5.x will happen in
master. For now though master will track the 0.4.x series. Core
Change GeglParamSpecSeed from int to uint to match the value range
of GeglRandom's seed. Operations
ripple fixed remaining issues needed to remove legacy GIMP plug-in
in GIMP. spherize, requrise transform and color-overlay moved out
of workshop. ppm-load ported to GIO.

• ff-save fully store all in-flight codec contexts before closing files
• ff-load improvements to seeking accuracy
• transform: make fast paths skip pixel format conversions
Header location and library names changed, so bump API version.
No users in pkgsrc (yet).
Changes in GEGL 0.3.0
---------------------
• Improvements to thread safety and parallelism.
• Lower overhead graph travesal due from rewrite of visitors
• OpenCL support now enabled by default when detected.
• Experimental multithreading, enable by setting
GEGL_THREADS=<number of threads> in the environment.
• Experimental mipmap rendering, which permits transparent rendering of
previews on smaller sized versions, enable by setting
GEGL_MIPMAP_RENDERING=true in the environment.
• Operations:
• new operations: alien-map, antialias, apply-lens, bilateral-filter,
bump.map, cartoon, channel-mixer, color-enhance, color-exchange,
color-reduction, color-rotate, convolution-matrix, copy-buffer, cubism,

• reimplementation of gaussian-blur faster and more accurate
• support for using URIs in image loaders
• Buffer:
• New default tile backend, doing disk writes in a separate thread.
* OpenCL support
* build improvements.
* High level API to apply ops directly to buffers with arguments.
* Final bits of translation infrastructure.
* Invalidate regions when disconnecting input pads.
* Operations:
* New operation: global-matting
* Allow transform core to do perspective transforms.
* Added string based key/value pairs to operations.
* Added arguments for dealing with scaled down preview rendering.
* Added human interaction ranges and non-linear mapping to properties.
* Buffer:
* Removed broken lanczos sampler.
* Add gegl_buffer_set_color and gegl_buffer_set_pattern
* Added ability to drop cached tiles.
* Added API for handling abyss policy (not implemented yet)
* Avoid iterating global tile cache when flushing/destroying buffers
that have no tiles in the cache.
* New operations: max-rgb, pixelise, motion blur.
* Fixed a bugs in matting-levin that made GEGL halt due to errors
detected by babl sanity code, this made 0.1.4 be unusable if you had
all dependendency when building.
* build/test improvements.
* Buffer:
Added API to use external tile backends, allowing to plug-in alien
tilebackends, for GIMP/Krita/OSM or similar.
* Renamed gegl:load-buffer to gegl:buffer-source and gegl:save-buffer
to gegl:buffer-sink (but the old names still work)
* Represent colors using doubles instead of floats (this change is
independent from internal processing)
* Removed the GTK+ UI parts of the gegl binary and turned gegl into a
pure command line tool (which can still visualize stuff with help
help the SDL based display operation)
* Consider {x=G_MININT/2, y=G_MININT/2, width=G_MAXINT, height=G_MAXINT}
as the only valid region wichin processing may occur. Processing
outside of this region is undefined behaviour.
* Added support for storing allocation stack traces for GeglBuffers
so that debuging buffer leaks becomes much easier
* Made small changes and cleanups of the public API, e.g.
* Removed gegl_node_adapt_child()
* Made GeglConfig an explicit object
* Removed most of the ifdeffed stuff to mask away internal structures
* Added gegl_rectangle_infinite_plane() and gegl_rectangle_is_infinite_plane()
* Added new sampler GeglSamplerSharp
* Added format property go gegl:buffer-sink
* Cleaned up and made gegl:introspect work again
* Add a bunch of test cases using the automake test sytem (make check)
and also port buffer tests to automake
* General cleanups, bug fixes, increased robustness and improved documentation

Ruby: yes
Cairo: yes
Pango: yes
pangocairo: yes

* gegl:opacity - combine value and aux mask input when both are available.

* gegl:path - new op covering the stroke/fill needs of SVG.
* deprecated gegl:shift, the affine familiy of operations now
uses the same fast code paths for integer translations.

GeglNode
* made gegl_node_add_child and gegl_node_remove_child public API.

by default, the infrastructure allows extensions from applications with
other curve types (smooth curves, spiro curves and others.).
framework.
GEGL provides infrastructure to do demand based cached non destructive
image editing on larger than RAM buffers. Through babl it provides
support for a wide range of color models and pixel storage formats for
input and output.
