[Openexr-devel] 2.0.0 problem with RgbaInputFile and 32 bit images

[Peter Dimov]

Hello,

I've recently upgraded to 2.0.0 (from 1.6.1) and am having problems with 
reading 32 bit images via RgbaInputFile. I changed nothing in the actual 
reader code, just switched the OpenEXR library. While 1.6.1 reads 32 bit 
(float) images correctly, 2.0.0 doesn't. By the look of the produced image, 
I suspect that the library writes 32 bit floats into the Imf::Rgba frame 
buffer, instead of half. 16 bit images read fine.

I suspect a regression in the RgbaInputFile, but it's possible that I'm 
either doing something wrong in the client code, or have somehow managed to 
compile the library incorrectly. Going by the symptoms, I suspect the 
library itself is at fault though.
