[Openexr-user] exr channel tools?

[Erik Winquist]

hi,

to anyone's knowledge, are there existing opensource command-line
tools out there for merging EXR channels from different images,
removing channels from images, renaming channels, adding user
strings, etc? i see something called EXR Tools, but that currently
only performs filtering/color operations on RGBA images.

i'm basically looking for something similar to the EXIFutils suite,
but for OpenEXR.

any info would be great!


cheers,
erik

for merging EXR channels from different images

and just to clarify, by merge, i mean in the concatenation sense, not a
compositing operation.

e.g.
if image A contained [red, green, blue, alpha]

and image B contained [blah, foo, skrit, blammo]

merging the two sets would produce an 8-channel image.


that sort of thing..

cheers,

You should be able to do all of these operations with pfstools
(http://pfstools.sf.net/), but some will require writing scripts in
Octave. The limitation is that pfstools store all channels (except
color channels) in OpenEXR in 32-bit float format.
