I need to create an action wizard that will add some white space to PDFs without changing the size of the document, so I have to shrink the content. This is so I can add a watermark to them without impeding any of the content on the document.
I did find a half solution to this which was to add a 1 inch header to every page but I have many different PDFs all with varying sizes. Where this might work for most of the PDFs on the larger ones the watermark becomes too small to read if it is printed.
So, I need to be able to add some white space as a percentage of the page size. This way it will not matter how big or small the PDF is the watermark will still be legible.
