[GM-help] 16 bit grayscale PSD bug

[Alex T. <al...@ac...>]

Hello,

    Just a quick bug report regarding the conversion of 16 bit grayscale PSD files. It seems GM
cannot understand them, or is getting confused. Converting to JPG, the result looks like static.

[gouda:root]/home/alex# gm convert 16bit_grayscale.psd 16bit_grayscale.jpg

You can download the test image and the result here:
