EXR images not correctly loaded for visualization

[Gurprit Singh]

Hi Wojciech,

I wanted to submit a bug report. On Mac OS Sierra (10.12.6), I am unable to see images correctly. It seems to me the number of channels are not correct, example screenshot attached in a .zip file. While uploading the files I don't see any error message on the terminal. It seems like everything works fine but the final visualization is not correct.

The old version of HDRView that I was using till Siggraph this year was showing me the images correctly.

What commit/branch are you using? I'm not able to reproduce this using the development branch. Everything seems to work fine.

I also just tested the master branch (on macOS High Sierra 10.13) and it also works fine. I suspect this might actually be an openGL/graphics card issue.

I used to explicitly set the pixel row length for OpenGL textures, and removed this at some point in the last few months. It didn't affect my systems, but maybe this was in fact needed. Could you try with the latest commit in the development branch?

I updated the hdrview with your recent commit in the develop branch but it still shows the same problem.

I also would like to mention that sometimes I do get a correctly loaded image but it happens only few times, mostly I get the wrong image. This was also the case before I submitted the bug report yesterday.

I've tried this on two computers now, though both on High Sierra, and I'm not able to reproduce this issue. It's not going to possible for me to debug this. If you track down the issue, I would welcome a pull request.
