Hello all,
We just upgraded from 6.2.4 Q16 (Debian) to 6.4.2 Q16 (Debian) and now I
can't get jpeg compression to work (-compress jpeg).
The following shows output from
"convert <file1>.tif -compress jpeg <file2>.tif"
In 6.2.4 this worked (tiffinfo shows compression as JPEG) and in 6.4.2
fails (tiffinfo shows compression as None).
Has compression been broken? Do I need to invoke it differently?
Thanks in advance.

PerlMagick is a fully supported API, the ImageMagick developers wrote
it.
> PythonMagick seems like it is even less supported.
PythonMagick is a contributed ImageMagick wrapper. We did not write it
and
we do not support it.
