GEGL 0.0.18
⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺
GEGL (Generic Graphics Library) is a graph based image processing 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.
This development release will include optimizations for the cpu capabilities
of the host system. Pass --disable-mmx and --disable-sse to configure to
disable these when building packages that should work on a wider range of
hardware. Making GEGL adapt at runtime is a blocker for the next release.
There is no new API in this release thus bindings do not need to be updated.
Changes in this release
⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺
• Configuration both from commandline arguments and at runtime.
• GeglBuffer
• New raw tiled raster file format, used both as swap and stored buffers.
• Sharing between processes through synced swap.
• Babl powered scan iteration infrastructure for efficient access.
• Cubic and lanczos samplers re-enabled.
• Operations
• Use scan iterator for point-filter, point-composer and point-render base
classes internally for minimal amount of copies.
• Optimized variants of some point and compositing operations
reimplemented using a new data type /g4float/ that allows writing cpu
agnostic vectorized code for GCC.
• New temporal filter base class, for operations operating on color values
from neighbouring frames in a video stream.
• Autogenerated operation reference installed for use with devhelp.
• New operations: write-buffer, v4l, color-temperature.
A new release of babl is also available for the quickest operations GEGL work
best with babl-0.0.22 or newer.
