possible bug cmyk separation IM 6.7.6.6

Post by fmw42 »

IM 6.7.6.6 Mac OSX Snow Leopard.

I don't know if this has been reported already, but converting an RGB image to CMYK and separating channels shows the black channel to be in color.

We can reproduce the problem you posted and have a patch. Look for it in ImageMagick 6.7.6-7 Beta by sometime tomorrow. Thanks.
