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
