[Openexr-user] Does OpenEXR Handle Large Images

[Ben Thompson]

Hello Everyone,

I'm trying to create large HDR image files. I have been using 
applications that write both .hdr and .exr; I have been using the former 
for no special reason.

However, it seems that the applications generate invalid .hdr files when 
the image is more than 32767 pixels wide. I believe this is because they 
write RLE-compressed .hdr and RLE is not supported for images this wide.

I'd like to know if .exr files have any limits on image size both in the 
case of no compression and compression with each/any of the available 
compression methods. I know of RLE, Zip (with and without 
multi-scanline, PIZ and PXR24.

Thanks,
