Subject: | [Openexr-devel] 2.0.0 problem with RgbaInputFile and 32 bit images |
Date: | Fri, 17 May 2013 16:05:33 +0300 |
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.
