Enable the recommended preset and fix or per-line-disable the 78
findings it surfaces. Most are equivalent rewrites, intentional
patterns (control chars, the whatwg email regex, autolinker URL regex)
keep their behavior via targeted disables.
Fixes#21259.
Reset letter-spacing and word-spacing on the text layer and hidden measurement canvas so inherited page styles do not affect text layer alignment. Add an integration regression test for inherited spacing.
This patch is generated automatically using `npm audit fix`, and brings
the number of reported vulnerabilities back to zero by patching:
- GHSA-jxxr-4gwj-5jf2: "brace-expansion: Large numeric range defeats
documented `max` DoS protection"
- GHSA-58qx-3vcg-4xpx: "ws: Uninitialized memory disclosure"
It fixes#7625.
If the Top DICT's Private DICT extends past the end of the font data,
the Local Subrs INDEX is unreachable and every CharString that calls
a subr ends up as a blank glyph. Throw from parsePrivateDict so the
existing catch in translateFont triggers fallbackToSystemFont, then
run getFontSubstitution post-construction so we pick a close local
match instead of the generic fallbackName.
Some Type1 fonts (the embedded Optima variants in orw1972.pdf) ship
two /Subrs and /CharStrings blocks wrapped in save/restore frames
gated on an Adobe hires/lores runtime switch.
In such cases, we just use the first /Subrs and /CharStrings block,
which is the one that is actually used by the font renderer in Acrobat.
It fixes#18548.
In many/most PDF documents every glyph will require that the character BBox has scaling/offset applied, which can be made a tiny bit more efficient. In particular:
- Avoid creating one additional temporary Array for every glyph.
- Simplify the helper function, since there's no skew-components.
When comparing this code with the full `XRef` class it doesn't seem to be entirely correctly implemented, since the `fetch` method is basically doing what the `fetchIfRef` method is intended to do.
Prune the back-edge components from cyclic composite glyphs in
sanitizeGlyphLocations (leaving non-cyclic siblings intact), reject OS/2
tables whose length is too short for the declared version so a clean
table gets regenerated, and upgrade a version 0.5 maxp table to 1.0 for
TrueType fonts to silence OTS' "wrong maxp version for glyph data".
It fixes#21298.
Drop an external PDF anywhere in the views-manager thumbnail
sidebar to merge it at the cursor, rather than always inserting
after the current page via the "Add file" button.
The drop reuses the blue separator from page-move drag so the
user can see exactly where the inserted pages will land, and the
merge path is shared with the existing picker so post-merge
selection/current-page behavior stays consistent.
