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.

Identification

Files usually begin with ASCII text "/* Format_version=1". Sometimes there's an SCCS comment before that, e.g. "/* @(#)black.cursor 85/08/19 1.1 SMI */
