in reply to HTML image resizing with Image::Info based on max height/width

Can someone see if this would work?

#!/usr/bin/perl use warnings; use strict; my $height = "1000"; my $width = "1234"; my $maxh = "600"; my $maxw = "800"; if ($height > $maxh || $width > $maxw) { my $hratio = $height / $maxh; my $wratio = $width / $maxw; my $newh = $height / $hratio; my $neww = $width / $hratio; print "Height is now $newh, Width is now $neww"; }

    It's not quite as trivial as it might seem at first (most of us who have tried probably got it wrong the first time :)

    Just as an example, take a width of 1000 and a height of 100. Your algorithm would compute 6000x600 (W x H), although the expected result would be 800x80 (i.e. max width doesn't exceed 800 and aspect ratio stays at 10:1)
