[FFmpeg-devel] [PATCH]lavc/psd: Interpret duotone as grayscale

[Martin Vignali]

Hello,

Seems strange, that duotone is interpreted like grayscale
(i doesn't test yet your patch)

You can find a sample here (and an rgb png of the result in photoshop), for
a duotone file with color

I think, duotone, need to be interpreted using information in Image
Ressource

I never use Duotone before, so i can't really help to the right way to
interpret this kind of file
