misterMatt has asked for the wisdom of the Perl Monks concerning the following question:

Hi guys. I wrote a tiny script that creates a pdf file by searching a directory for a list of jpg image files and then adding them to separate pages inside the pdf. It works fine, thanks to the example code I found online (the PDF::API2::Lite docs really really suck), but I was wondering if I could make it work more generic by having the ability to add any images in a directory, like gifs, pngs, ect. - not just jpg files. I was under the impression that $pdf->image($file) would be able to do that. I have tried using my $image = $pdf->image($file);, and then $pdf->image($image, 0, 0); to then add the image to a page that I created but I get this error: 'Can't call method "image" on an undefined value'. Here is the code I have that works:
#!usr/bin/perl -w use strict; use PDF::API2::Lite; #concatenates all files in a specific directory into a pdf file that w +ill #be spit out into that same directory upon completion #grab a list of files in our very special directory. my @files = sort glob('path\to\jpgs\*') or die "No files"; #xreate a new document with no pages my $pdf = PDF::API2::Lite->new; #loop through our images, create a page for each image # - while adding the image to the created page for my $file (@files){ my $image = $pdf->image_jpeg($file); $pdf->page($image->width, $image->height); $pdf->image($image, 0, 0); } $pdf->saveas('output.pdf');

    Instead of using "image_jpeg($file)" you have to use the various specialized image functions, such as "image_gif($file)" and "image_png($file)". See a fuller list of image type commands here:
