The advantage to these is that you can combine multiple color profile transformations into a single mapping so that it's considerably faster (especially when dealing with large images).
Instead of something like:
Code: Select all
-intent Relative -profile sRGB.icm -profile CMYK.icc -profile sRGB.icm
The tifficc tool comes with lcms is capable of this but I can't seem to make it work in ImageMagick.
