[Gegl-developer] Operations that I require

[Mark Probst]

Hi!

I've already reached the first problem: My operation (the mono channel
mixer) takes an RGBA image as input, but produces a YA image.  I want
to make it a point operation, but I can't use the input buffer as
output, so I thought I could set the output buffer using
gegl_operation_set_data, but that requires a context id which I don't
have.  Is there a way to make this a point operation or do I have to
implement it as a generic operation?
