Hi Guys. I gained a lot of ground since i asked my last question on this subject - and I have the script working perfectly for jpg images. The jpg files are added to the pdf without incident, but when I uncomment the lines that add png or gif files to the pdf document the script fails and gives me two different errors: one for png images, and one for gif images. They are: (1)Can't call method "val" on an undefined value at C:/Perl/site/lib/PDF/API2/Resource/XObject/ line 99. and (2)unsupported graphic control extension (255) at C:/Perl/site/lib/PDF/API2/Resource/XObject/Image/ line 229. I'm not exactly sure that the errors are tied to a specific format - but they seem to correlate the way I posted when I comment out the png line, or I comment out the gif line. Anyway. I'm absolutely not at all sure what is causing these errors - because the code is exactly identical to the jpeg image code, and that works without any hiccups. Any ideas guys? Here is the code I'm looking at right now with the two lines that are causing problems commented out inside of the for loop:
#!usr/bin/perl -w use strict; use PDF::API2; #concatenates image files of type JPEG, GIF, and PNG in a specific dir +ectory into a pdf file that will #be spit out into that same directory upon completion #very fun print "Input a filepath to a directory (ending with a /. ex: 'C:/path/ +to/dir/'): "; my $dir = <STDIN>; chomp $dir; print "\nInput the name for the pdf file you wish to create (ex: 'pict +ures'): "; my $pdf_name = <STDIN>; chomp $pdf_name; #grab a list of files in our very special directory. my @images = sort glob("$dir*") or die "No images\n"; #xreate a new document with no pages my $pdf = PDF::API2->new; #loop through our images, create a page for each image # - while adding the image to the created page -> this is done in the +subs for my $file (@images){ #call sub based on what regex matches add_jpg($file) if ($file =~ /.jpg/); #add_png($file) if ($file =~ /.png/); #add_gif($file) if ($file =~ /.gif/); } $pdf->saveas("$dir$pdf_name.pdf"); #subs sub add_jpg{ my $jpg = shift; my $image = $pdf->image_jpeg($jpg); my $page = $pdf->page(); $page->mediabox(0,0,$image->width, $image->height); $page->trimbox(0,0,$image->width, $image->height); my $gfx = $page->gfx; $gfx->image($image, 0, 0); } sub add_png{ my $png = shift; my $image = $pdf->image_png($png); my $page = $pdf->page(); $page->mediabox(0,0,$image->width, $image->height); $page->trimbox(0,0,$image->width, $image->height); my $gfx = $page->gfx; $gfx->image($image, 0, 0); } sub add_gif{ my $gif = shift; my $image = $pdf->image_gif($gif); my $page = $pdf->page(); $page->mediabox(0,0,$image->width, $image->height); $page->trimbox(0,0,$image->width, $image->height); my $gfx = $page->gfx; $gfx->image($image, 0, 0); }
I'll post this in the code section once this is sorted out and it's working ok.
