Graphic editor on Suns?

[Siasb Zanganeh]

Does anyone knows where can I find a public domain or commercial graphic
editor which works on sun workstations (sun 3) and has a close enough
features as GEM on Pc's? If possible, I would like to have the source code
and manuals along with the software. Otherwise an interface which could be
used from C code. Please send me any information on this subject.  Thank
you.
