[Radiance-general] pcomb problem

[Giovanni Betti]

Thank you so much Thomas, your tip fixed the problem in one second!
Would be useful to have the right syntax on the manual page as well though...

Thanks again,

Best,

Giovanni

Have you tried to use double quotes instead of single quotes?
I noticed that there is a difference between command prompt
in Windows and shell prompt in Unix. Can't remember which
one had to use on Windows, though.

With this weekend's HEAD I noticed that the -h command does
strip the headers from the input images, but the command used
to create the output is still there in full length. I can understand
that this is the desired behaviour. If you plan to combine a large
number of pictures I would recommend another pcomb command
with a single input file just to strip this header as well.

Thomas
