Hi Martin,
exrmaketiled attempts to read the entire input image at once; the
program is not smart enough to process the image incrementally.
The highest-resolution level of a 20k by 20k 16-bit RGB image
requires about 2.4 GBytes of memory. The lower-resolution levels
of a mip-mapped image consume another 0.8 GBytes. To process a
20k by 2k image with exrmaketiled you'll need a computer with
at least 3.5 GBytes of RAM, and you'll probably have to build
the program in in 64-bit mode.

Hello again!
While trying to convert a 20k * 20k EXR into a tiled one:
exrmaketiled.exe -m -v test.exr test_tiled.exr
I get this error message on Windows:
reading file test.exr
bad allocation
Same when using the -r or -o option.
Seems as if the file is too big for exrmaketiled?
Does anyone know some alternative software I could use to produce a
tiled EXR?
Thanks!
Martin
