Hi!
First time poster so please excuse any mistakes made. I've tried submitting
a patch through git send-email but got issues authentication through gmail.
Attached is a patch file created with git format-patch.
Commit message:
Added support for version field flag 0x04 in OpenEXR files regarding long
names in attributes.
Should have no impact on decoding of images.
Also added a bit more verbose logging of OpenEXR 2.x flags not yet
supported.
