    ImageMagick has a convert tool that can convert just about any format to any other format. There is also a perl module to interface with it.

    We're not surrounded, we're in a target-rich environment!

      If ImageMagick is installed on Linux or Windows, try this...

      my $command = 'convert name.ppm name.jpg';
      system($command);

      Hi,<br< I am getting an error when I try to install the module.
      make error

        You can't be serious.
        "make error"? is that it?

        update: Have you read the Tutorials? I recommend that you start at the top and work you way down.

    The Independent JPEG Group's free implementation of JPEG (which is required for JPEG support in most any package, including ImageMagick) includes a program named "cjpeg" for doing exactly this. "djpeg" does the reverse.
