Yes, virtually all image processing and compositing will be performed in the linear light RGBA color space with 32 bit float depth per channel. There have been discussions about introducing regression tested optimizations for 8 and 16 bit depths, but I don't expect any effort to be put into that soon. First, we need to finalize getting GEGL into GIMP. > What exactly happens when you select the "use GEGL" menu item right > now? It uses GEGL but only with the current capabilities?

However, the data being processed is stored as RGBA u8. That means that if you do an color adjustment with Use GEGL enabled, then you first have to convert that data to RGBA float for processing, and than back to RGBA u8 to store it again. In other words, not very useful to the end user. If you in the yet not officially released GIMP 2.7 do View -> Use GEGL, then the layers will be composited using GEGL. In other words, we have the layers etc ported to a GEGL graph. It is worth mentioning that it is technically trivial to insert non-destructive nodes in the graph, but our focus now is getting GIMP 2.8 out. / Martin _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
