How to rotate text while creating PDF in Zend Fram

Question

I am placing text on pdf something like this using Zend_Pdf:

$page1->drawText( 'Hello World!', 100, 100 );

But now I want to rotate text to 90 degree on pdf. How is it possible ??

Thanks

Answer 1

You can use rotate() which uses Radians to determine the amount to rotate.

For example:

    // Rotate at the X and Y coordinates 
    // and 90 Degrees Counter-Clockwise (which is 1.5708 Radians)
    $page->rotate(300, 300, 1.5708);

Use this tool calculate the value from degrees. Whilst you can use the constants in PHP and divide (as the other answer suggests) I would not recommend that personally (as I find it much harder to work out what it equates to).

You do need to rotate back before continuing with the next lines (assuming you want them to be horizontal).

Answer 2

How about:
$page->rotate(0, 0, M_PI/12);
$page->drawText('Hello world!', 100, 100);
