You don’t have to mody an existing delegate in the system delegates file. You can create your own delegate.xml file in a “.magick” sub-directory of your home. You will need to name the delegate something new however.

If you do this you can create say a “pscmyk:” delegate to handle CMYK postscript files while leaving the normal postscript handling of IM alone.

This also means you don’t need ‘root’ previlages to make the change needed.

See IM Examples, Delegates

(section still under construction) for more details.
If you do develop a “delegate” please contribute.

Need a bit more help here… I have already installed ImageMagick on a windows machine. I can find the delegates.xml file but don’t see any block of code similar to above. I have not yet installed GS. Can I just run the GS exe and will modify the IM delegates file to include the GS stuff? I don’t want to mess anything up in the IM setup at this point.

Thanks.

This is exactly the information I need to get the color under control during conversion. The only question I have is if the patch is still needed with the latest version. If it is how do I go about getting GS patched? I get terrible color conversion from CMYK PDF to RGB image. Even with profiles it has no effect.

Thanks!
