Hi I have a problem with pdf::api2 I need to edit an existing pdf and put in some images. The problem is that for inserting 4 images it takes around 20 seconds per image. So the whole process goes up to minute and a half. Is there some magic i can do to speed up the process? The images are 1920 × 1080 and need to stay that size, because i need quality pdf-s... So without further ado, here is the code:

#!/usr/bin/perl
use PDF::API2;                                      
print "start ".(localtime)."\n";               
$pdf = PDF::API2->open("sample.pdf");           
$page = $pdf->openpage(1);
$page->mediabox(840,600)
$gfx=$page->gfx;
print "first image ".(localtime)."\n";          
$first=$pdf->image_png("first.png");
print "inserting first image ".(localtime)."\n";
$gfx->image($first,134,106,510,281);
print "saving ".(localtime)." \n";
$pdf->saveas('new_file.pdf');
print "done ".(localtime)." \n";

The output i get:

start Mon Jun  3 10:46:31 2013
first image Mon Jun  3 10:46:31 2013
inserting first image Mon Jun  3 10:46:53 2013
saving Mon Jun  3 10:46:53 2013
done Mon Jun  3 10:46:57 2013

So the most time consuming process is image_png which takes 22 seconds in this example... Any help would be appreciated. Thanks

Update: if i use the same image converted to JPEG, it works flawlessly, under a second. The problem is i need the transparency of the PNG files
