Question

At the moment I am using this code to insert text in a PDF:

$pdf = Zend_Pdf::load("test_document.pdf");
$font = Zend_Pdf_Font::fontWithPath('arial_unicode_ms.ttf');
foreach ($pdf->pages as &$page) {
   $page->setFont($font, 12);
   $page->drawText("Inserted some text.", 200, 10);
}

The problem is, that I want to include this functionality in a Joomla plugin and I don’t want to include all the data from Zend Framework to my project.

Is there any easy way or any small library which provides this pdf tagging mechanism?

If you still want to use Zend_Pdf, you’ll probably need to have a look at the dependencies in the Zend/Pdf directory. You can grep for require_once to have a rough idea, and filter out the Zend/Pdf results:

grep -r require_once Pdf.php Pdf | grep -v "Zend/Pdf"

The first step outputs Zend_Memory, Zend_Exception and Zend_Log.

You can follow a similar method to check additional dependencies, and you’ll see that Zend_Memory needs Zend_Cache, which needs only Zend_Log, which is self-contained, like Zend_Exception. I think you won’t need to go much further, once you have included these four additional libraries.

EDIT: I found this link that lists all the dependencies between ZF modules (don’t know how up to date it is, though): http://files.zend.com/help/Zend-Framework/requirements.dependencies.html

Hope that helps,
