How can I create a multi-panel pdf from multiple files
I would like to create a pdf file made up of 4 image panels generated from 4 existing pdfs, e.g. Fig1.pdf on the upper left-hand side, Fig2.pdf on upper right, etc.
In Adobe, the options Create > Combine Files into Single pdf will merge Fig1.pdf through Fig4.pdf into a single pdf, but in linear order, giving me no control over position, size, etc.
Is there a straightforward way to create a multipanel figure (single pdf file) from multiple pdfs in the way that I describe in Adobe Acrobat?
