- 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.
