Sun icon is a raster image format, used for icons on some Sun operating systems.

Images are usually bi-level. 8-bit grayscale or palette color images are possible, but may not be portable (no palette is stored in the file).

Format

Sun icon files are entirely ASCII text. They have a header delimited by "/*" and "*/", followed by a comma-separated list of hexadecimal numbers.

Files usually begin with ASCII text "/* Format_version=1".

TODO: Figure out if Sun cursor files use the same format, and if .cursor and .pr filename extensions should also be listed.
