With the image incomplete.exr (rendered by Houdini as scanline, zip1,
pixel data is missing from scanline 139 on) execute:
oiiotool.exe incomplete.exr --autotrim -o incomplete_trimmed.exr
This will write the output image and not complain about the broken input
image. In my mind this should error (message to stderr), return an error
code and NOT write a totally black incomplete_trimmed.exr. This is even
more important when working on incomplete.exr in-place:
oiiotool.exe incomplete.exr --autotrim -o incomplete.exr
Right now the half-rendered incomplete.exr is overwritten by an empty exr.

I'm not sure that any behavior with incomplete images is
"intentional". Whatever we do with incomplete image that isn't to your
liking, is either a bug, or a default behavior that we haven't really
thought through.
Can you give an example oiiotool command line involving this image,
and explain what you'd like it to do in that case?

On a second note I found that oiiotool is also not setting the
correct exitcode (1) when dealing with broken images of any kind.

Hello,
sometimes we have incomplete exrs from renderings. When using
oiiotool to convert those images, oiiotool will silently convert
them ignoring the incomplete/broken file state, resulting in
completely black converted images. I think it would be better for
oiiotool to fail in this case. Other tools (like iconvert) already
do. Or is this behaviour intentional? (I have attached a small image
demonstrating the issue).

Sebastian
