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, 661
