Hi Mathias,
I have just checked in your workaround with a tweak to support
multi-byte colour channels. I don't have any such files to test
against so I can only hope that its correct. I works fine for your
sun.rgba and fine for all the OSG's own .rgb's. A cvs update will get
this fix.

It appears to me that the length of the run length encoding is wrong.
That change limits that to the min of the value from the file and the
remaining line length. May be this is suficient?

I do not know how the RGB file format that good to tell if those files are

Thanks for the link. I have searched through my mailing list archive
