resize gif using ImageMagick

[Anonymous Monk]

Hi, I am having a few problems with the following:

use Image::Magick;

@dir_names = ("images_small");

opendir(DIR,"output_gif");

foreach (readdir(DIR)) {

     /^(\d+).*/;
      $filename = $1;
push @file_convert, $filename;
                        }

opendir (DIR, "output_gif") or die "$!";

foreach $dir_name (@dir_names) {

    foreach $file (<@file_convert>) {
$filename_orig = "output_gif\/$file.gif";
print "\tOrig = $filename_orig";
$filename_new = "$dir_name\/" . $file . ".gif";

   $image = Image::Magick->new;
    open (IMAGE, "$filename_orig") or die "$!";
    $image->Read(file=>\*IMAGE);
    close (IMAGE);

   $image->Resize(geometry=>"12.5%");
 $image->Trim;
 $image->Set(page=> '+0,+0');

open (IMAGE2, ">$filename_new") or die "$!";
 $image->Write(file=>\*IMAGE2, filename=>$filename_new);
 close (IMAGE2);

 }
 }

the correct filenames are being written to the new directry images_small but the files are empty?

Try:

#$image->Write(file=>\*IMAGE2, filename=>$filename_new);
$image->Write($filename_new);

thanks for that, seems to have done the job

You should either open & close the file and pass ImageMagick the filehandle, or you give ImageMagick only the filename. From the Docs:

$x = $image->Write('x.png');
warn "$x" if "$x";

sorry not sure if i understand correctly?

Do as zentara suggests.
