I have written a small application in .NET that gives color to Illustrator files. It basically does things:
I have a layer with 100 color items (paths with a fillcolor). Each one has a unique name. Through that name my program looks them up, takes the fill color and applies that color to another path.
Recently there was a change in Design, the drawings that I had to provide of a Fillcolor were no no longer pathitems but rasteritems (imported from photoshop). I thought ok no problem instead of setting the Fillcolor property I'll use the Colorize method on the rasteritems. It worked fine but now and then I came across a situation where rasteritem didn't get the color. After digging in to it I saw that it was because some colors are Pantone colors and the colorize method on rasteritems only takes RGBColor or CMYKcolor objects. Any suggestions on how to do it with the pantone colors?
