Branch: CURRENT, Version: 0.4.12, Package name: gegl-0.4.12, Maintainer: adam

GEGL (Generic Graphics Library) is a graph based image processing

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.

Required to run:
[graphics/jasper] [graphics/png] [graphics/jpeg] [graphics/openexr] [graphics/librsvg] [x11/gtk2] [graphics/babl] [textproc/json-glib]

Required to build:
[pkgtools/x11-links] [x11/xcb-proto] [x11/fixesproto4] [pkgtools/cwrappers] [x11/xorgproto]

Update to 0.4.12

GEGL-0.4.12 2018-10-23


Fix fix of scaled blitting, the fix from last release introduced scaling
artifacts for all formats that are non-8bit.

Contributions to this relase

Ell, Øyvind Kolås and Rodrigo Lledó

GEGL-0.4.10 2018-10-16


Fix integer overflow issues for u32 blit scaling code paths.

Reduced memory clearing overhead for temporary buffers during blit.

Round alpha component during u8 bilinear/box filtering (this caused artifacts
on OSX through interaction without unknown platform differences in
libc/compilter/graphics stack)

gegl_buffer_dup now matches source buffer abyss, shift and tile-size more

Added GEGL_TILE_COPY command for backends, for more efficient buffer

New GeglBufferIterator API.

Move type-generic scaling algorithms to GeglBuffer folder, move opencl
integration bits out of buffer.


gif-load: new operation for decoding GIF images/animations, with frame delay
exposed as an out-property.

exr-save: do not hard-code a version name space
long-shadow: add 'Fading (fixed length)' style with a new user-defined
'Midpoint' parameter

maniuk06: use double precision, permitting to work on larger images.

watershed-transform: improved description

unsharp-mask: permit std-dev radius of up to 1500px (from 300).

Updated all operations to use new iterator API

Fixes to races during buffer/tile storage destruction, improve swap usage for
stored empty tiles.


 motion-blur-circular - improve/clarify property ui
 median-blur          - added abyss-policy property
 long-shadow          - new operation
 little-planet        - adapt reference composition

GEGL-0.4.4 2018-06-02


Point filters with need for format conversion of input are now
parallel. Added swap-reading, swap-writing, swap-read-total and
swap-write-total properties to GeglStats.


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


threshold: operating format changed from linear to perceptual
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
overflow due to logic error in pixelize. new operation: gegl:abs which
negates negative values. new operation in workshop:

gegl: update to 0.4.2.

GEGL-0.4.2 2018-05-15


Abort early if autoreconf fails, remove unused bits, default to -Ofast


Improve concurrency for trimming and destruction of tile caches.
Improve cache invalidation during partial mipmap regeneration.

Do new cheap clones of buffers with new internal gegl-buffer backed

Do not keep cached sampler in buffer it makes cache invalidation hard,
and for performance/threading it is better to create ones own samplers
anyways. The old API still exists, though parts of it is now
deprecated. The single special case where gegl_buffer_sample remains
somewhat performant is with the NEAREST sampler, for all other samplers
creating a caching sampler is better.


operation: add GeglOperationAreaFilter::get_abyss_policy() vfunc
Copyright notice improvements to spherize, color-overlay. ff-save:
implement defines handling compilation with ffmpeg 2.3-2.7, 4.0 compat.

Improved multi-threaded performance of panorama-projection and other
transformation operations through optimizations in buffer and
