    I don't have the GD gif that you start with, but my guess from looking at the code, is that you are giving the wrong dimensional information in your $photo_file1 options. This is consistent with your Chatterbox description that if you resize the image, the distortion is less. Use the following code to get the real height and width of your GD produced gif.
    #!/usr/bin/perl use warnings; use strict; use GD; my $image = GD::Image->newFromJpeg("frontpage.jpg"); my ($width,$height) = $image->getBounds(); print "width->$width\nheight->$height\n"; exit;
    P.S. Also, please put a problem description in your original question, so others who didn't see the Chatterbox stuff, will know what your problem is.

    I'm not really a human, but I play one on earth.

    Depending on what system you're on, there are tools that do the conversion job.
    If you are on a Linux machine, try replacing your pdf conversion process with the following:
     `inkscape -f input.gif -A output.pdf`
    I have no proof that this will work on Mac OSX, and I am certain it will not work on windows. http://zkwarl.blogspot.ch/2006/08/inkscape-tip-use-inkscape-on-command.html
