A nice, simple library for reading and writing all varities of Targa Files. Targa is a VERY simple image format, so it is convenient for storing your shit when doing image/video analysis. Also, I use targa because 3DSMax can output animations to a series of Targas, one for each output frame. I use these as test input for my video analysis code.
