* Thu Aug 23 2018 bjorn.lieAATTgmail.com- Update to version 0.4.8: + Core/GeglBuffer: Fixes to races during buffer/tile storage destruction, improve swap usage for stored empty tiles. + Operations - motion-blur-circular - improve/clarify property ui - median-blur - added abyss-policy property - long-shadow - new operation - little-planet - adapt reference composition- Changes from version 0.4.6: + Up until now GEGL has been using a color space corresponding to scRGB as an unbounded device independent/possibly scene-referred HDR color space - with a similar approach to to how ACEScg works but with a worse set of RGB primaries. babl formats, represented by a pointer and a corresponding encoding/format string have been used to specify the specific encoding of pixel values. The encoding including component order, data type and TRC encoding. Where \"RGBA float\" means 32bit float data and \"R\'G\'B\' u8\" the \' indicates non-linear, and thus this is sRGB. \"RaGaBaA half\" gives premultiplied linear half data. Other encodings and conversions are also provided through these formats including \"CIE Lab float\" and \"HSV float\". + As a color management workflow for scene-referred imaging the above could be sufficient, but GIMP needs data in the 0.0-1.0 range for some display referred blending modes to work properly. As a consequence of this recognized short-coming GIMP has been passing the pixels of for instance ProPhoto \"R\'G\'B\'A float\" off as \"R\'G\'B\'A float\" and linear ProPhoto \"RGBA float\" as \"RGBA float\" this works for single operations, but falls apart when the colors are converted to CIE Lab. This is the good enough state where the other benefits of having a stable release powered by GEGL outweighed not being entirely correct. + Since babl 0.1.32 of october 2017, all babl formats have an associated unchangable space associated with them, and since then GeglBuffer has worked correctly with it - since GeglBuffers use of babl API did not change. GIMP is already using these parts of babl for ICC matrix based conversions since using babl for ICC profile transforms is an order of magnitude faster than using the lcms2 library. It took time to come up with the above scheme of integrating arbitrary primaries and curves for spaces with babl in a maintainable manner, and it has taken until the last month to come up with a full plan for the rest of GEGL to be aware of and handling arbirary parametric ICC v2/v4 based color spaces for operations; without limiting the ability to extend and use the code for a wide range of scenarios. + A space can be constructed from a preferenced name/specification, loaded/saved from ICC matrix profiles or constructed and serialized to whitepoint + rgb chromaticities / xyz matrix. More recently an additional trc mark has been added \'~\', giving this vocabulary for RGB formats, in addition to variants with alpha and pre-multiplied alpha variants of the same: - \"RGB\" linear primaries from space, linear data - \"R\'G\'B\'\" non-linear primaries from space, TRCs from space - \"R~G~B~\" perceptual primaries from space, sRGB TRC + When creating device independent CIE based spaces they also get passed a space, this means that we can convert CIE Lab to RGB float, keeping track of which space / ICC profile the data correspond to. + GEGL operations now construct their desired encodings of formats by taking the space of buffers on input pads into account. By default, for composers \"input\" wins over \"aux\" to determine ops space. If an operation is not ported, data will be converted to sRGB on input and sRGB will come out of the node. + Buffer loaders PNG, JPG, TIFF and EXR generate custom spaces based on ICC profiles/primaries. The corresponding savers saves color space information. A new save handler for the .icc extension, acts like an image storer but only saves the ICC profile of the buffer it gets on input. + With no additional operations inserted, this now means that GEGL graphs operate on linear / non-linear variants of the color space used in the input images without conversion. The new operations gegl:cast-space and gegl:convert-space provide means of overriding this behavior, see the new section about color management in the gegl-chain syntax documentation at http://gegl.org/gegl-chain.html + Initial work has started on making GIMP also use of and propagate color space information along with encoding in babl formats, changes which also will be integrated in the 2.10 branch. + Other changes to operations: vignette: fixes to gamma property + New operations: - cast-space: assign/override color space - convert-space: convert to a different color space - litte-planet: stereographic-mapping split out of the panorama-projection + New operation in workshop: acrs-rrt: ACES RRT based HDR to SDR proof/preview point-filter tonemapping op.
* Thu Jul 05 2018 bjorn.lieAATTgmail.com- Update to version 0.4.4: + Core: - 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. + Buffer: - Trim tile-cache when shrinking. - Added reading locks to tiles further improving concurrent access tolerance of GeglBuffer. + Operations: - 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. - Fixed integer overflow due to logic error in pixelize. - New operation: gegl:abs which negates negative values. - New operation in workshop: selective-hue-saturation.
* Wed May 16 2018 bjorn.lieAATTgmail.com- Update to version 0.4.2: + Build: Abort early if autoreconf fails, remove unused bits, default to -Ofast as CFLAGS. + GeglBuffer: - 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 tile-backend. - 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. + Operations: - 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 base-classes.- Drop gegl-port-ffmpeg4.patch: Fixed upstream.

* Fri Apr 27 2018 bjorn.lieAATTgmail.com- Update to version 0.4.0: + 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.- Rename subpackages following upstreams soname bump.
