pdf::api2 page question

[tonyperl]

i just finished writing an invoice with pdf::api2. i start with a template that i open and print invoice line items to that page. when that page is full i create a new page. after printing several pages and just before i close/save the pdf and move on to the next doc, i'd like to figure out how many pages i have and then reference the first page and add page 1 of n pages to the bottom of the page. then i'd like to go to the next page and print page 2 of n pages etc... Does anyone know a good approach for doing this?

Umm .. Knowing that you have n pages, go back and iterate over the pages, adding Page m of n at the bottom of each page?

For pages that I generate, my data is pre-processed from a database into an array of hashes. So each slot in the array is a page. No need to go back and place page numbers, just get the total page count from $#data, and then increment the current page number using a variable within the loop. This method may not work very well though if you are generating thousands of pages per document.

Why not?

thanks for the advice. i ended up making an array of pages and then at the end i cycled through the array and numbered the pages based on $pdf->pages; so i had something like $elementNumber of $pdf->pages; at the top of each page. i guess what i was trying to figure out is if this couldn't be done through the pdf object. i figured that every time a page object was created $pdf->page; the page would be put on a list owned by the pdf instance -- yeah totally goofy don't know what i was thinking...
