PDFs in a slideshow folder now play alongside images and Word documents:
a one-page PDF is shown whole, a longer one fits the width and scrolls
through its pages during docInterval (first 30 pages - rendering a huge
PDF for a few seconds on screen isn't worth the time and memory).
- kiosk-app/pdf-render.mjs renders pages to canvases with pdf.js
(pdfjs-dist ^6.3.289, new kiosk-app dependency): no viewer toolbar, and
the slideshow's existing auto-scroll works on it. pdf.js >= 4.2.67 is
required (CVE-2024-4367: older versions could run script embedded in a
crafted PDF); isEvalSupported:false too. It's a module because pdf.js
only ships as one - confirmed to load (with its worker) from file:// in
Electron 44.
- Hands pdf.js a copy of the bytes: it transfers the buffer it's given,
which would break the cached copy the next time round.
- slideshow.js lists .pdf as a document type; the title-request handler
serves any listed non-image item (still only from that folder).
- provision_install_app now copies kiosk-app/*.mjs as well - without it
pdf-render.mjs would never reach an installed kiosk.
Tested with the real main.js on Electron 44.5.1 under Xvfb + Openbox,
app files copied with provision_install_app's own glob: a photo, a
one-page PDF, a three-page PDF and a .docx played in order, twice round;
the one-page PDF shown whole, the three-page one scrolled through all
pages. Offline bundle rebuilt with pdfjs-dist (437 MB total, +22 MB).
