Currently the defauly abyss color is 0,0,0,0 (RGBA). What would have
to be done to allow users to specify their own abyss color?

Thanks,
Eric

Since the abyss logic is in GeglBuffer (gegl-buffer-access.c), I would
add the abyss color as a property to the GeglBuffer.

Thanks for the reply.

How would I pass this information from my XML test file to gegl-buffer-access.c?

Example XML code (image rotation test using my upsharpfast sampler):

0.000000
0.000000
7.000000
upsharpfast




data/roemerlogo_large.png

Thanks,
Eric

The properties in the XML file are set on operations, and GeglBuffer is
not an operation.

You can add a property to gegl:rotate and pass that along to GeglBuffer.
Perhaps not the prettiest, but it would work.

Sorry, I should have been more specific.

The rotation script is just one example of tests being done on the
samplers. I am also doing scaling operations. An example of this
would be:

What would be the most general way of getting this abyss color to
gegl-buffer-access.c?

Thanks again,
Eric

gegl/operations/affine/affine.c

would take care of rotation and scaling and a few other things,
although it probably is still not general enough.
