Description Manuel Albert 2016-05-18 10:45:34 UTC 
For professional work we create Multilayer OpenEXRs (half float) for animations and stills. None of the files created could yet be opened in Krita. 
Some files are really HighResolution (6480x4484 with lot's of layer). Opening those files just shows loading progress until it crashes. 
Smaller Animation Frames do load, but before the image is displayed the App-Crashes.

Windows 7 64bit, 24 Gig RAM, 2x GTX 980 (non SLI)
Krita Version tested after short twitter (user: manuelalbertcom) conversation: 
krita-3.0-RC-1-master-6f75b0f-x64.zip (64 bits) 

Reproducible: Always

Steps to Reproduce:
1. Open the File

Actual Results:  
Nothing or Crash

Expected Results:  
Open the file and display the layers

For better investigation I uploaded a sample file:
http://download.creamsurfer.de/krita_bugreport/samplefile.exr (this is a production file/testrender)
Comment 1 Halla Rempt 2016-05-18 11:06:49 UTC 
Hi Manuel,

Thanks for your report. I can confirm the crash with your samplefile, it's really useful to have access to that!. How were the files created?

Notes:

* The actual OS doesn't matter. 
* It's not a regression from Krita 2.9: that crashes as well on these files.

The backtrace from Krita 3: (From 2.9 is similar, also happens in allocating tile data)

The files were created in blender (the version number should be 2.76 but we work with latest version most of the time and none of them produced something useful).

exr_converter.cc patch

I found out that layers can have their own colorspaces. The converter appears to use the colorspace for the entire document rather than the colorspace for the layer, so they are not loaded properly and we get those errors. I put the check for the colorspace in the layer instead of the document in this patch, but there are other issues. It gets to loading a "Vector" layer (possibly GLASSES) and stalls completely. I think it has something to do with the while loop in the unmultiplyAlpha call because it gets stuck while processing a pixel, returns no error messages and doesn't crash.

beelzy, please use phabricator for review requests, we lose them here :) (You just use your forum account in the ldap area and then submit the patch via differential)

Use the layer's not the image's type when reading pixel data

Make sure the alpha value is positive when unmultiplying

Otherwise the loop will never end. The image in the
referenced bug now loads.

Thank you for the fixes. If you need other files to test, I can supply you other samples.
Comment 11 Halla Rempt 2016-05-30 10:20:09 UTC 
I'm still not sure Krita really loads the files correctly, though :-)
Comment 12 Manuel Albert 2016-05-30 15:27:23 UTC 
I prepared a few samples today and uploaded them to my webspace: http://download.creamsurfer.de/krita_bugreport/samples_openEXR.7z
http://download.creamsurfer.de/krita_bugreport/16bitfloat_zip_singlelayer_CC_Multipass.exr (this was created using different colormanagement options and contains only one Renderlayer but multiple passes)

I don't know if they're helpful, yet I tried to put together a few different cases (e.g. like 16bit float and 32bit float options).

If I can help out in any way, please tell me what you need. 

Thank you. You guys rock!

This has been fixed.
