Sun rasterfile run-length encoding

[David Heath]

I'm writing a sun rasterfile reader. It works fine on 1, 8, and 24 bit
images in RT_OLD and RT_STANDARD formats. I would like to get it working
for the RT_BYTE_ENCODED format. I understand the general principle behind
run-length encoding, so could probably figure out sun's format eventually,
but has anyone already decoded their format?

I have checked out /usr/include/rasterfile.h and rasterfile(5), but
neither answers this question.

Thanks!
