       "imnum" is a comma-separated list of integers indicating the images in order that they
       appear in the PDF.  Use listimages to retrieve the image numbers.

DESCRIPTION

       Requires the ImageMagick convert program to be available

       Tweak all of the JPG images embedded in a PDF to reduce their size.  This reduction can
       come from increasing the compression and/or rescaling the whole image.  Various options
       give you full control over which images are altered.
