I see. Since iconvert does fail, I thought this is an oversight in
oiiotool. A command line flag is totally fine. Just to be sure, I dont
know if it makes any difference: I am not talking about tiled images.
These are scanline images.

How about a command-line option for oiiotool that would trigger a
failure upon a tile read error?
I don't necessarily want it to be the default, because apparently an
EXR file which is missing tiles is still a proper EXR file, and at my
work we have a couple circumstances where this is used purposely and
need those images to process correctly.

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
