@cantoo/standard-fonts

Metrics and encodings for the 14 standard PDF fonts. Fork of chbrown/afm (via @pdf-lib/standard-fonts), vendored for @cantoo/pdf-lib.

Benefits vs original afm / @pdf-lib/standard-fonts

| | afm | @pdf-lib/standard-fonts | @cantoo/standard-fonts | | --- | --- | --- | --- | | Unicode → WinAnsi / Symbol / ZapfDingbats | ❌ | ✅ | ✅ | | Compressed metrics in the package | ❌ (raw AFM-derived) | ✅ (pako) | ✅ (fflate) | | Runtime inflate | — | pako | fflate (unzlibSync) | | Packaging | Standalone | Standalone | Also @cantoo/pdf-lib/standard-fonts (vendored under src/packages/) | | Metric regen tooling | Make / ad-hoc | Makefile.js + ts-node / shelljs / mz | yarn standard-fonts:metrics (Node fs/promises + Buffer, esbuild runner) |

Compared to stock afm, you get encodings plus small compressed JSON metrics suitable for browsers. Compared to @pdf-lib/standard-fonts, you drop pako, align with @cantoo/pdf-lib / @cantoo/fontkit, and get a maintenance path that does not depend on legacy Make/ts-node scripts.

Usage

import { Font, FontNames, Encodings } from '@cantoo/standard-fonts';

const glyph = Encodings.Symbol.encodeUnicodeCodePoint('∑'.charCodeAt(0));
const font = Font.load(FontNames.Symbol);
const width = font.getWidthOfGlyph(glyph.name);

Also available via @cantoo/pdf-lib/standard-fonts when pdf-lib is installed (no extra dependency).

Regenerating metrics

From the pdf-lib repo root (after editing AFM or encoding source files):

yarn standard-fonts:metrics

Or separately: yarn standard-fonts:afm / yarn standard-fonts:encodings.
