README

https://github.com/mozilla/pdf.js Legacy build, from the GitHub release ZIP (the npm pdfjs-dist package does NOT contain web/viewer.html, web/viewer.js, web/locale/ or web/cmaps/): https://github.com/mozilla/pdf.js/releases/download/v3.11.174/pdfjs-3.11.174-legacy-dist.zip v3.11.174

VNote-owned files in this folder are NOT part of pdf.js and must be preserved across an upgrade:

• pdfviewer.js
• pdfviewercore.js
• pdfviewer.css
• web/pdf-viewer-template.html (stock web/viewer.html with three edits: the <title>, and the VX_STYLES_PLACEHOLDER / VX_SCRIPTS_PLACEHOLDER comments in place of the stock <link>/<script> tags)

web/locale/ is deliberately trimmed to a subset of the upstream locales; keep web/locale/locale.properties in sync with the folders actually vendored.

Not vendored from the ZIP: *.map source maps, web/debugger.{js,css}, web/compressed.tracemonkey-pldi-09.pdf, and the top-level LICENSE.

Why v3 and not v4+: Qt 5.15's QtWebEngine is Chromium 83, and pdf.js's legacy build requires Chrome 125+ from v4 on. v3.11.174 is the last v3 release.
