EXR bounding box and convert hang

[timurhai]

Hi.
I have convert tool hang operating with EXR which bounding box is larger than resolution.
Process (convert) just hangs event if i only want to "-identify -verbose" an image.

I think (and expect) that without any options for data behind the resolution, image should be just cropped to the resolution.

Here is a normal exr file (no data out of resolution):
http://cgru.info/rules/rules_root/test/ ... orbars.exr

Here i just scaled the image by 10% within the same format (resolution is not changed, bouding box is larger than resolution):
http://cgru.info/rules/rules_root/test/ ... scaled.exr

Code: Select all

$ convert -identify -verbose colorbars_scaled.exr /dev/null
*** Error in `convert': free(): invalid next size (normal): 0x00000000015c56e0 ***

ps
I just want to generate a thumbnail from an image file and do not need any data out of resolution.

Does this work?

Code: Select all

identify -verbose colorbars_scaled.exr

The fault is in the EXR library. The bug is either in the EXR ImfInputSetFrameBuffer() library call or we're calling it incorrectly.

Code: Select all

identify -verbose colorbars_scaled.exr

- the same error
