the source GimpColorProfile

 

src_format

the source Babl format

 

dest_profile

the destination GimpColorProfile

 

dest_format

the destination Babl format

 

rendering_intent

the rendering intent

 

flags

transform flags

 

Returns

the GimpColorTransform, or NULL if no transform is needed to convert between pixels of src_profile and dest_profile .
