Zend Framework PDF Page resize (scale) / rotate (page not an element)

Question

is there any possibility to resize an Zend_Pdf_Page Object from (e.g.) DIN-A4 to DIN-A6 (or any other size)?

i would like to merge 4 PDF (1 page) files to 1 pdf file (1 page). in each edge should be one of the 4 pdf files.

positioning, grid, e.g. is no problem... but how can i change the document size (of an existing pdf file) and how can i rotate the whole document?

i work with ZF1, but if the only way to fix this problem is to use an external library - no problem.

PS: sorry for my bad english (hope it is enough to understand my problem)

also tried with imagick to convert pdf to image, but quality is too bad for printing as those small thumbs... :-(

Answer 1

Technically your requirements could be done by transforming the page into a so called form XObject which can be place on a new created page. That's how FPDI works: http://www.setasign.com/products/fpdi/demos/thumbnails/ (maybee an alternative for you).

I just checked the code of ZendPdf but I cannot find any method that may allow this.

Rotation can be done with FPDF/FPDI too: http://fpdf.org/en/script/script2.php

In your code, if you have something like $page = new Zend_Pdf_Page(); you can set here the desired dimensions.

For example, you can write $page = new Zend_Pdf_Page('297:420'); for A6 format (if I'm not mistaken).

To represent an A4 page in landscape (wide) orientation, you can write
$page = new Zend_Pdf_Page('a4-landscape');
or
$page = new Zend_Pdf_Page(Zend_Pdf_Page::SIZE_A4_LANDSCAPE);

You can look at the documentation or the source code of the constructor of the Zend_Pdf_Page class for more information.

I hope it will help you. :)
