I'm putting together some code that will write an icon file (obtained via NSWorkspace) to a gif.I had prototyped the code with a simple command-line tool with hard- coded values for file sources, destinations, and image sizes. However, when I try to abstract the code, I am now getting weird error messages:<Error>: CGImageCreate: invalid image size: 0 x 0.2009-03-13 10:40:48.805 Wish[20760:10b] Could not create CGImageRef - w:0, h:0, bps:8, bpp:32, bpr:512, alpha:0x1, cSpace:NSCalibratedRGBColorSpace, hasAlpha:1, isPlanar:0
Log your width and height values to see what they really are. You appear to be using 0, 0. Incidentally, setPixelsWide: and setPixelsHigh: do not do what you appear to think they do. You could also check [icon isValid] to make sure the image is available.

This is because you are incorrectly managing memory for icon and resizeicon. Check the docs on that again.
