I imagine they've fixed it by now, but both ImageMagick and GraphicsMagick leaked memory last time I used them, which made them unsuitable for use in a long running process handling millions of images. Switching to FreeImage not only allowed for cleaner code, it was faster and didn't leak. http://freeimage.sourceforge.net/ http://freeimage.sourceforge.net/
