I’ve got a better idea. I can tile them ten to a page, baseball-card size, and I won’t need any guide lines. 2.5+2.5+3.5=8.5
Since there are different numbers of cards on the page, need to cut them all out first (card_cutter_10up.pl), then paste them together in groups of ten (card_paster_10up.pl).
Printing from Preview, the dpi is actually about 359.1 (not 360), which is imposed by specifying the resolution when converting to PNG.
I also tried 8-up, just like as-shipped. Worked out fine, but I still like 2.5×3.5.
- Deal with odd numbers of cards at the end.
- Write out as TIFFs instead of PNGs (pnmtotiff -lzw), cat them (tiffcp), & convert to PDF (tiff2pdf -z). Will need to specify resolution at some point.
