GEGL 0.1.0⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺GEGL (Generic Graphics Library) is a graph based image processing framework.
GEGL provides a graph based API and framework to do demand driven, cached, nondestructive image editing of larger than RAM images. Through babl it providessupport for a wide range of color models and pixel storage formats for inputand output.
This is the first release in the 0.1.x development series, APIs have beenoverhauled the graph API is now considered pretty stable. Note that tomigrate existing 0.0.x series code to 0.1.x you need to prefix operationnames with "gegl:"
To build gegl-0.1.0 you will also need the newest version of babl.
Changes in this release⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺⎺ • Renamed gegl:load-buffer to gegl:buffer-source and gegl:save-buffer to gegl:buffer-sink (but the old names still work) • Represent colors using doubles instead of floats (this change is independent from internal processing) • Removed the GTK+ UI parts of the gegl binary and turned gegl into a pure command line tool (which can still visualize stuff with help help the SDL based display operation) • Consider {x=G_MININT/2, y=G_MININT/2, width=G_MAXINT, height=G_MAXINT} as the only valid region wichin processing may occur. Processing outside of this region is undefined behaviour. • Added support for storing allocation stack traces for GeglBuffers so that debuging buffer leaks becomes much easier • Made small changes and cleanups of the public API, e.g. • Removed gegl_node_adapt_child() • Made GeglConfig an explicit object • Removed most of the ifdeffed stuff to mask away internal structures • Added gegl_rectangle_infinite_plane() and gegl_rectangle_is_infinite_plane() • Added new sampler GeglSamplerSharp • Added format property go gegl:buffer-sink • Cleaned up and made gegl:introspect work again • Add a bunch of test cases using the automake test sytem (make check) and also port buffer tests to automake • General cleanups, bug fixes, increased robustness and improved documentation
