[sane-devel] problems with scanimage to pdf

[Carsten Jensen]

I'm wondering why your converted image is in little-endian and the rest
are big-endian.

you might want to provide wich kind of computer you're using, whats the OS.
and how did you install Imagemagick, as it seems that is the reason for
the problem.

Try using other programs to manipulate your image to eliminate thich
application causes the problem.
i.e. use gimp to rotate and save again.
