Re: [Gimp-developer] Of Palettes and Plug-ins

[Warren Turkal <wt penguintechs org>]

I thought that the palette loader code that is currently there created a
palette before putting it in the UI. However, upon closer inspection, each
of the loaders appear to create a palette based on the filename being
imported, then the common code in gimp renames the object. Given that the
current code isn't importing the palette atomically, I will just do the
same thing. I think I see how to make this work.

This has been helpful.

Thanks,
