Iterate plural PDFs with scaled font sizes.

aplonis has asked for the wisdom of the Perl Monks concerning the following question:

The Problem: I publish EPubs but some readers still clamor for PDFs, in which the font size is set in stone. I can convert them to PDF but then the font size is set in stone, too small for some, too large for others. A pain it would be to manually convert plural versions, each time resetting Calibre's base-font size only for the PDFs.

My Question: How might I, via Perl, read in a single, Calibre-generated PDF at the default base font size, and iterate an output of two additional PDFs, each of successively smaller sizes at, say, 75% and 50% of the base...or 10pt and 8pt...whatever?

aplonis: Changing the font size in a PDF file will cause you some problems unless you change the page size as well. If you don't change the page size, then you'll have to recompute the page layouts, or you'll have quite a messy PDF file. Since calibre is apparently generating your PDFs, I'm guessing that it does page layout at the same time. If so, I'd suggest telling it the font size to use when generating the document. (Note: I'm assuming that calibre allows you to configure the fonts for PDF file generation.) ...roboticus When your only tool is a hammer, all problems look like your thumb.	[reply]
