Peter,

This is expected behaviour. Little-endian PC writes little-endian TIFF,
big-endian PC writes big-endian TIFF.

If the output is not a valid TIFF file, or there are *significant*
differences between the two, could you post the output of tiffdump for
both the little-endian and the big-endian version of the same output
file?

You say you're using version 3.8.2 on the Windows PC. Which version are
you using on the PowerPC?

PDF has different ways to represent image description data from TIFF.
Maybe tiff2pdf doesn't copy everything. Can you be more specific?
Is there a difference between Windows and PowerPC here? Are you using
the same version of tiff2pdf?
