# We have to use jpegtopnm with the original JPG before being able to compare
# it with imagemagick because imagemagick will decode the JPG slightly
# differently than ghostscript, poppler and mupdf do it.

# slightly different results as well when called like this:
# djpeg -dct int -pnm "$tempdir/normal.jpg" > "$tempdir/normal.pnm"

# method when decoding by setting -define jpeg:dct-method=ifast in the
