[Gegl-developer] GEGL-0.3.0 babl-0.1.12

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-0.3.0 you will also need babl-0.1.12 and a recent version of glib,
follow see the output of the configure script for details.

Changes in this release:

 • Improvements to thread safety and parallelism.
 • Lower overhead graph travesal due from rewrite of visitors
 • OpenCL support now enabled by default when detected.
 • Experimental multithreading, enable by setting
   GEGL_THREADS=<number of threads> in the environment.
 • Experimental mipmap rendering, which permits transparent rendering of
   previews on smaller sized versions, enable by setting
   GEGL_MIPMAP_RENDERING=true in the environment.
 • Website/documentation: split website in more pages, added op
gallery and API browser.
 • Operations:
   • new operations: alien-map, antialias, apply-lens, bilateral-filter,
     bump.map, cartoon, channel-mixer, color-enhance, color-exchange,
     color-reduction, color-rotate, convolution-matrix, copy-buffer, cubism,
     deinterlace, diffraction-patterns, distance-transform, displace, edge,
     emboss, engrave, exposure, fractal-trace, high-pass, image-compare,
     illusion, invert-gamma, lens-flare, linear, linear-gradient, mosaic,
     motion-blur-circular, motion-blur-zoom, noise-cell noise-cie-lch,
     noise-hsv, noise-hurl, noise-pick, noise-rgb, noise-simplex, noise-spread,
     n-point deformation ops, oilify, panorama-projection, photocopy, plasma,

   • reimplementation of gaussian-blur faster and more accurate
   • support for using URIs in image loaders
 • Buffer:
   • New default tile backend, doing disk writes in a separate thread.
