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