Lightweight imagemagick wrapper?
You can exclude most any image format you don't need in the ImageMagick/coders folder. A few may be required by the MagickCore API such as xc.c. If you build a static version of the library you need to remove the register calls for any format you exclude from magick/static.c. Make sure you are using a recent version of ImageMagick. We moved the command line methods from MagickCore to MagickWand. With a bit of extra effort you could probably remove some image methods you don't need from the MagickCore API.
