I've noticed this issue with some images on the latest Radiance 4.2 versions as well.
Greg, the length of the file name doesn't seem to have any effect for me -- the errors remain the same. I've been ignoring the problem, so haven't traced the reason as for why it occurs, but it tends to manifest itself with Radiance images generated in certain atypical ways: (1) HDR photographs and (2) renderings using electric lighting via IES2Rad.
fyi in case anyone was trying to pipe falsecolor / gencumulativesky-generated
pics
through pfilt lately, the same error seemed to occur in this scenario - glad
it'll be cleared up
Well, pfilt hasn't changed in 4 years and pcond hasn't changed in 8, so my
only remaining guess is that the new way we're calling popen() under Windows
is somehow at fault. This call that was hand-written by Georg Mischler was
recently replaced under Microsoft's Visual-C compiler, and I think the issue
is that I'm not explicitly setting the binary file type in pcond. Schorsch's
win_popen() must have done this for me without my realizing it.
I have checked in the new module and it should get recompiled at some point.
My apologies, and I hope this solves the issue.
In the short term, just use the older version of pcond. It's the same,
anyway.
Cheers,
-Greg

I'll try to reproduce the error again when in front of the work machine and let
you know- if I recall correctly I just fed a DIVA-generated HDR (from a
rpict+gencumulativesky run) to pfilt, and it wouldn't eat it. Could not figure
that one out.
Umm... maybe not. This is specific to pcond -- I didn't find a similar
oversight in any of the other programs. Can you tell me what command(s) are
giving your errors, exactly?
Thanks!
