Zend PDF mixes up Width and Height of a Page

Question

I'm using Zend_Pdf, and at one point I am reading my source page's Width and Height using $page->getWidth(); and $page->getHeight();

Most of the time it reads fine.

Sometimes, however, Zend PDF returns are the opposite - it shows 11in as width and 8.5in as height for a standard Letter-sized PDF. I can't figure out why it would do that.

I tried saving the PDF in question as 1.4, as PDF/A, but the result is all the same.

Answer 1

After a bit of investigation I was able to figure it out.

Turns out the page was coded as having "Rotate" set to 270 degrees.

You can access this variable inside Zend_Pdf_Page:

$this->_pageDictionary->Rotate->value

Then if Rotate is set to 90 or 270, I reverse Width and Height.
