pdf2image.raku - Convert a PDF to PNG, or SVG images, using Perl 6!


pdf2png.p6 [options] infile.pdf [outspec.png]


Options:
  --password=str       # provide a password for an encrypted PDF
  --page=n             # render just this page
  --trace --debug      # debugging/tracing


This program bursts a multiple page into single page PNG files.


By default, the output pdf will be named infile-001.png infile-
                002.png ...


The `outspec`, if present, will be used as a 'sprintf' template
for generation of the individual output PNG files.


** This is neither fast, or complete ** It exists to exercise other
components in the Raku ecosystem, including PDF::Content and Cairo.
