UPDATE:As marto points out, the OP's question was the number of images in a PDF file, not the number of pages. Thus the below is not the answer asked for. I have never used it, but quickly browsing the documentation you linked in your post I found that you can use the 'pages' function: $pagenumber = $pdf->pages Returns the number of pages in the document. For Example: `use PDF::API2; my $pdf = PDF::API2->open('test_file.pdf'); print "'test_file.pdf' has " . $pdf->pages . " pages\n";` [download]	[reply] [d/l]

etm117, anniyan is asking how to determine the number of images not pages within a PDF file. CAM::PDF comes with a script called listimages.pl which you should look at anniyan. Hope this helps. Martin	[reply]

Wow!, My bad... I hadn't had my first cup of coffee yet, and I must have read the word 'images' as 'pages'. Sorry for the confusion anniyan	[reply]

I don't see how one can cycle through the objects in the PDF document in PDF::API2. From what I see, it gives you the ability to add objects but not browse through current objects. What would be useful in your case would be the ability to cylce through all objects in the document and if the "Type" of the object is "XObject" and "Subtype" is "Image", then you know you have come across an image. -imran	[reply]
