GEGL (Generic Graphics Library) is a graph based image processing framework.
GEGL provides a graph based API and framework to do demand driven, cached, non
destructive image editing of sparse storage of larger than RAM images
- using CPU or GPU
processing. Through babl it provides support for a wide, and extendable, range
of color models and pixel storage formats for input and output.
To build gegl-0.2.0 you will also need babl-0.1.10
Changes in this release:
• OpenCL support (experimental, enable by setting the environment
variable GEGL_USE_OPENCL to the value yes)
• 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:
• Removal of 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.
