Trying to center PDF with PDF::Resize

[Booger]

Dear Monks:

I am attempting to merge two existing PDFs together with prDoc by writing:

prFile('my_output_pdf.pdf');
prDoc( { file => 'file1.pdf' } );
prDoc( { file => 'file2.pdf' } );
prEnd;

This does as one would expect and results in the two PDFs being merged and placed in the file my_output_pdf.pdf

My problem, however, is in convincing the second PDF that is merged using prDoc to center itself on the page.

Is there any way to go about centering an included PDF on the resulting page? I've tried using prFile with the CenterWindow and FitWindow options and neither of these seem to do anything.

Any suggestions or comments would be greatly appreciated.

Thank you,

Matt
