Windows Icon

Quick Info

Windows icons are stored either as ressources in executable files, or in seperate icon files. An icon file can contain up to 65535 icons, however, I've never seen so many. Icons can be 16x16, 32x32 or 64x64 pixels large. They may also contain transparent pixels (there's a transparency mask). Truecolor is not supported.

To edit an icon, or extract single icons from a file, you can use Microangelo
