in reply to creating thumbnails

This is from a small test script I wrote yesterday. It creates a thumbnail while retaining image proportions.
#!/usr/bin/perl -w use strict; use Image::Magick; sub make_thumb { my $file = shift; my $thumb = shift; my $size = 100; # image size; either width or height will be a 100 + pixels (or both) my $img = new Image::Magick; $img->Read($file); my ($width, $height) = $img->Get("width", "height"); if ($width > $height) { my $ratio = $size / $width; $height *= $ratio; $width = $size; } elsif ($height > $width) { my $ratio = $size / $height; $width *= $ratio; $height = $size; } else { $width = $size; $height = $size; } $img->Resize( width => $width, height => $height, blur => 1 ); $img->Write($thumb); } make_thumb("/path/to/img.png", "/path/to/thumbnail.png");
