[Gegl-developer] raw support

[Hubert Figuiere]

Hi,

I'm writing on RAW support for GEGL. I was wondering a few things:

1/ what is the best pixel format I should use for the CFA data. I chose
"Y u16" because it is 16-bits (from 10 to 14 actually) and just the
luminance. But it there something more suited?

2/ how do I propagate metadata? I need to specify the CFA pattern, the
min and max values and other things need for the proper interpolation. I
have no idea how to do that from the GeglOperation


Attached is the first shot at a patch that approximately output black
only.
