[Openexr-user] exrmaketiled error

[Martin Breidt]

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

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.

I'm trying to compile openexr on suse10.2 64 bit. The configure appears
to work, but I get this error doing "make".
