Topic: attachment_fu, rmagick and colorspace conversion from CMYK to RGB

Hello,

I am trying to find a way to convert images on upload (attachment_fu handles upload and resize using rmagick) from CMYK color space to RGB. Is this even possible?

So far I have found that rmagick has color space attribute and constant (http://www.imagemagick.org/RMagick/doc/ … colorspace), but I don't see any indication that this can be used to uploaded CMYK image to RGB image.

Any ideas?

I would like to do the same thing.  I found a patch for Paperclip

Several browsers don't handle CMYK color space very well.
