File Format Conversions (RGB <-> CMYK)

Post by roycable »

Hi Everyone,

Was wondering what the best (and easiest) method of converting RGB <-> CMYK would be.

From what I can tell, ImageMagickWand seems to be the go, but that involves installing extensions to ImageMagick which some servers do not allow, and so was hoping there was an easier way of doing it.

I haven't found anything really solid with GD.

If the scenario is needed: user uploads EITHER a rgb (jpg) or CYMK (tiff) and then a bit of PHP script makes a duplicate but in the other format.

Any help would be appreciated.

Thanks

last I checked, GD has no TIFF services. The safest (or fail safe) solution is to find or create a PHP script that can do the conversion with as few external requirements as possible (fopen() and siblings would be ideal.) However, that requires a lot of processing and could take a lot of time depending on the size of the image to convert.
