Re: [Gegl-developer] Using GEGL on GIMP

[Zhang Peixuan <zhangpeixuan cn gmail com>]

Thanks a lot.

 

I still hope to continue adding code to GEGL,  so I would like to know what I can do next.

Now I have some difficult on building GIMP-goat-invasion on Windows. But I will continue trying it.

 

If there is any infomation, please tell me, thanks.

The TileSource and TileSink operations are being deperecated during
the GIMP-2.10 development cycle, please look at the goat-invasion git
branch of GIMP to see the new way things will be done.
