How can I make a PDF in a container 'fit one full page to window'?

[HALBURN]

I have a container field that auto resizes (both the width and height). When I view the container on a 1920 x 1080 display I can only see the top half of the document as it auto-resizes to fill the width.

 

There is a little button in the PDF viewer "fit one full page to window"  that resizes the document so the entire page is visible. Is there a scripted way to trigger this or some way that I can make "fit one full page to window" the default setting?

I found the solution to my problem. When saving the PDF with a script there is a button to set the PDF options. One of them is the initial view option.
