in reply to Suggestion - Image processing..

If you're worried about the performance of scaling in Imager you might want to upgrade to the most recent version and use the 'mixing' scaling method. This is significantly faster than the default. eg.

my $scaled = $src->scale(qtype => 'mixing', xpixels => 100, ypixels => 100, type => 'min');
