pdf.paperSize String|Array (default: "auto")

Specifies the paper size of the PDF document. The default auto setting means that the paper size is determined by the content.

The supported values are:

• A predefined size such as A4, A3, and so on.
• An array of two numbers which specify the width and height in points (1pt = 1/72in).
• An array of two strings which specify the width and height in units. The supported units are:
• mm
• cm
• in
• pt

The size of the content in pixels will match the size of the output in points (1 pixel = 1/72 inch).
