Re: Perl/Tk widget for displaying images and thumbnails

Image::Magic is a very powerful module to manipulate images. It may be of help to you. As an example, I use the following script to generate HTML formatted thumbnails from a directory of pictures. You can surely use the same concept in Tk.

use strict;
use English;
use Warnings;
use Image::Magick;
use Image::Magick::Thumbnail;

opendir(DIR,$ARGV[0]) || die "Can't open directory: $!\n";
open(FIL,">$ARGV[0]/index.html") || die "Can't write html file: $!\n";
print FIL "<html><body><center><table border=1 cellpadding=3 cellspaci
+ng=3><tr>";
mkdir("$ARGV[0]/Thumbnails") unless (-d "$ARGV[0]/Thumbnails");
mkdir("$ARGV[0]/Reduced") unless (-d "$ARGV[0]/Reduced");
my $i=1;
foreach (sort grep {/jpg$/i} readdir(DIR)){
  if (/Censored/){
    print "skipping $_\n";
    next;
  }
  print "reading $_\n";
  my $img = new Image::Magick;
  $img->Read("$ARGV[0]/$_");
  my ($thumb,$x,$y) = Image::Magick::Thumbnail::create($img,640);
  $thumb->Write("$ARGV[0]/Reduced/$_");
  ($thumb,$x,$y) = Image::Magick::Thumbnail::create($img,100);
  $thumb->Write("$ARGV[0]/Thumbnails/$_");
  print FIL "<td><center><a href=\"Reduced/$_\"><img src=\"Thumbnails/
+$_\"></a><br><font face=\"Times New Roman\" size=\"2\"><a href=\"$_\"
+>Lrg</a></font></center></td>";
  if (!($i++ % 6)) {print FIL "</tr><tr>";}
}
print FIL "</tr></table></center></body></html>";
close(FIL);
closedir(DIR);
