Please update it with your own ideas and findings. + +Porting GIMP to GEGL will be a multi-stage process. On a high level, +the stages are: + +Stages: +======= + + 1. Implement GIMP's 8 bpc code with GEGL data structures + 2. Gradually port GIMP's 8 bpc code to 32 bpc + 3. Once the GIMP base layer (almost) only knows 32 bpc and GEGL, add + goodies like adjustment layers and layer effects on top + + +First stage: +------------ + + 1. Kill Tile and TileManager + 2. Change PixelRegion::tiles : TileManager * to PixelRegion::gegl_buffer : GeglBuffer * + 3. Map PixelRegion::gegl_buffer of type RGBA float to PixelRegion::data of type RGBA u8 + 4. Implement functions like scale_region() with GEGL (for the + gegl_buffer case. For the data case, we can keep the old code) + 5. ??? + + +Second stage: +------------- + + 1. ??? + + +Third stage: +------------ + + 1. ??? |
