Formulated like that, this is GIMPs problem not GEGLs problem, one way to achieve this is to crop the resulting image to the pre-extended extents, I suspect that the result on the edges by doing this, will be roughly equivalent to what you get in GIMP when blurring a layer/rectangular selection etc. Another option is to define a new operation that doesn't grow, that also encodes the edge/abyss behavior (I hve written som GEGL operations based on random sampling of the neighbourhood that discards the random sample if it falls outside the defined area and does another random one instead). Another option that hasn't been fully explored that might prove more fruitful is allowing GeglBuffers to define the abyss/edge behavior. Whether the abyss is transparent blank (or opaque black for no alpha) like it is now or it mirrors/extends pixel data. /Øyvind K. -- «The future is already here.
