Hi. I hope this isn't too dumb a question, but I'm sort of stuck and could really use some help.
I'm trying to show how uploaded images will look when coming out of a printer -- not any particular model, just a generic test to show the difference between an RGB image and what a printer can output.
I've tried the following to convert it once to CMYK and then back to RGB for viewing through a web browser -- but it doesn't seem to do anything, not even an error:
convert uploaded_image.jpg -colorspace CMYK cmyk.jpg
mogrify -colorspace RGB cmyk.jpg
Even this still returns information saying that it's still an RGB image:
mogrify -colorspace CMYK uploaded_image.jpg
identify -verbose uploaded_image.jpg
I've also uploaded a printer icc file I have on my computer and tried this without any luck:
mogrify -profile /var/tmp/printer.icc uploaded.jpg
As per the instructions under -colorspace, I tried this to see what options are available, but it returns an error that "colorspace" is not a valid -list option:
identify -list colorspace
I'm sort of stuck with ImageMagick 6.0.7 running on RHEL 4, but I don't suppose it's the version I'm using that's the problem? If not, does anyone see what I'm doing wrong?
Thanks.
