TCPDF Page Rotation

Question

I am trying to create a PDF file containing tags with a width of 202 mm and a width of 50 mm. I managed to do this and added the required text and barcode, but the problem is that the labels first print a narrow edge, so the whole page should rotate 90 degrees.

I can do this in Adobe Reader with ease by simply right-clicking on the page and selecting Rotate Clockwise (Shift + Ctrl ++), but I really need to do this in code.

Does anyone know how to do this using TCPDF? I tried the Rotate function, but could not get it to work. Any code examples would be helpful.

Answer 1

How to configure it when creating a page?

TCPDF::__construct($orientation = 'L', $ unit = 'mm', $ format = 'A4', $ unicode = true, $ encoding = 'UTF-8', $ diskcache = false) 

$ orientation orientation (string). Possible values ​​(case insensitive):

• P or portrait (default)
• L or landscape
• '' (empty line) for automatic orientation

Answer 2

What I did with version 1.5

  $pdf->AddPage(); // Orientation for the first page is defined into configuration file. $pdf->writeHTML("Portrait 1"); $pdf->AddPage('L'); $pdf->writeHTML("Landscape !"); $pdf->AddPage('P'); $pdf->writeHTML("Portrait 2"); $pdf->Output(); 

And it works well.

Rotate is odd. What the docs aren't telling you is that you first need to do StartTransform , then do Rotate , and then do StopTransform . You can make a call to StartTransform after you somehow set the X / Y position (for example, I use SetXY for the initial position of the page, and then you can call StartTransform ). So try to do:

  $this->pdfinvoice->StartTransform(); $this->pdfinvoice->Rotate(-90); 

then add your content then call

  $this->pdfinvoice->StopTransform(); 

when you are done. See how it works for you.

The easiest option is to set the page in landscape mode "L" if that is what you need. Otherwise, if you need a page in portrait mode, but with rotated objects, you can create an XObject template and place your content there, including graphic transformations. Check out the default examples at http://www.tcpdf.org for graphic transformations and XObject templates.
