Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

How can I re-size an uploaded image with Perl? And is it possible to get the original height and width values of the uploaded image so I can re-size it proportionally?

Thanks,
Ralph.

    PerlMagick, a Perl module to access ImageMagick's functionality from Perl should do all you want (and probably much more ;-)

    Hope this helps, -gjb-

    I answered a question like this few days ago, please read node 209268 for code. There many modules that can deal with images on CPAN; the example I wrote uses GD and Image::Magick (part of PerlMagick mentioned by gjb).

    Ciao, Valerio

    This isn't the fanciest of ways, but it does the job easily without needing any new Perl modules. Just install ImageMagick, and then use its "mogrify" command-line utility from Perl: 
    system("mogrify -quality 50 -geometry 80x80 *.JPG");
