I'm just starting to play around with IM, and am having a few initial stumbling blocks.
I need to convert hi-res images (usually CMYK EPS files with clipping paths) to various other formats. On my first attempt, I had success converting a RGB file to a png file and having it clipped and trimmed the way I wanted and it looked good, but if I try the same with a CMYK file, the results are way too dark, and don't look at all like the colors in the CMYK file.
I have read up on changing the delegates.xml file, but have not had any success yet - the resulting png file still looks the same no matter what I have tried (adding either '-dUseCIEColor' or '-dUseCIEColor=false' to the delegate file). I have located 2 different locations for the delegates file, and have updated both of those each time. Do I need to do anything after replacing those files? Can someone help point me in the correct direction on what I need to do to fix this? I am on OSX btw.
One of the other problems I need to work with, is occasionally someone saves their EPS file from Photoshop with vector info (which they are not supposed to do). I was also looking into the output of the 'identify' command to see if I could determine if a file was saved this way, but I didn't see anything that I could tell indicated whether this was done or not.
Also, is there any way to identify the names of any extra channels? I sometimes need to find a channel to use as a mask by it's name.
Thanks for any input anyone can provide me.
