OpenType Unicode fonts for Scientific, Technical, and Mathematical texts

+

Overview

+ +

Type 1 fonts (STIX 2.0.0 only)

+

The STIX Two fonts are OpenType fonts and are meant to be used in that +format. For the benefit of LaTeX users who are unable to use XeTeX or +luaTeX, we have also provided version 2.0.0 of the STIX fonts as a +set of TFM files and Type 1 fonts.

+

Note that no further updates are planned to the Type 1 +distribution; future development efforts will focus on improving the +OpenType fonts.

+

About the STIX fonts.

+

The Scientific and Technical Information eXchange (STIX) fonts are +intended to satisfy the demanding needs of authors, publishers, +printers, and others working in the scientific, medical, and technical +fields. They combine a comprehensive Unicode-based collection of +mathematical symbols and alphabets with a set of text faces suitable +for professional publishing. The fonts are available royalty-free +under the SIL Open Font License.

+

Version 2 of the STIX fonts, now known as "STIX Two", is a thorough +revision undertaken by the renowned type house Tiro Typeworks +Ltd. (https://www.tiro.com). The STIX Two fonts consist of one Math +font, two variable text fonts (STIXTwoTextVF-Roman and +STIXTwoTextVF-Italic), and eight static text fonts (Regular, Italic, +Medium, Medium Italic, SemiBold, SemiBold Italic, Bold, and Bold +Italic) derived from the variable fonts. Together, they provide a +uniform set of fonts that can be used throughout the production +process, whether that be a traditional print-only process, an entirely +electronic one, or a combination of the two.

+

The STIX project began through the joint +efforts of +American Mathematical Society (AMS), +American Institute of Physics (AIP), +American Physical Society (APS), +American Chemical Society (ACS), +The Institute of Electrical and Electronic Engineers (IEEE), +and Elsevier. +These companies are collectively known as the STI Pub companies.

+

A Fresh Take on Times Roman

+

The original version of STIX was based on Times Roman, which has now +been updated for the digital age.

+

As is well known, Times Roman was originally intended for printing the +London Times. What is not generally appreciated is that the +production quality of the Times was atypically high: It was printed +on unusually high-quality paper on presses that operated more slowly +than most newspaper presses. This allowed for the design of a +typeface that could exploit this level of care: serifs could be much +finer and counters (enclosed areas such as that in the lowercase e) +could be much smaller than in other newspaper typefaces. These +features of the font have not always fared well in less exacting +environments. At the same time, a notable quirk of the Times Roman +family is that the bold font is, in many respects, strikingly +dissimilar to the roman font.

+

Tiro Typeworks explain their approach to updating the Times Roman +basis of STIX as follows:

+
+

“Our principal goal in approaching STIX Two was to address several +inherent deficiencies in the Times New Roman model as well as expand +the typographic features. This process necessarily involved +diverging somewhat from Times as familiar to people who have only +known the common digital versions, while simultaneously restoring to +that typeface aspects of the size-appropriate design characteristics +that made it so successful in newspaper, book, and journal +publishing in it’s metal type incarnation. The essential +‘Times-ness’ remains, but are with greater harmonisation of style +across the family.

+

“Most digital versions of Times have been based on an optical size +model that appears too light and fine when scaled down to typical +text sizes. In the design of STIX Two, we went back to specimens of +size-specific designs from the metal era, and adapted proportions, +weights, and spacing of the 10pt and 12pt designs. The oft-noted +mismatch between the style of different weights of Times has been +resolved with a new bold design that matches the construction of the +regular weight.”

+
+

Font implementation decisions

+
    +
  • +

    The STIX fonts do not contain fixed-width or sans serif text faces.

    +
    • +
  • +

    The sans serif, fraktur, script, etc., alphabets in Plane 1 +(U+1D400-U+1D4FF) are intended to be used only as technical symbols.

    +
    • +
  • +

    These fonts are designed to support left-to-right typesetting in +Latin-based scripts, with additional support for Greek and Cyrillic +text. Extensions to support other writing directions have been +considered, but are currently deemed to be outside the scope of the +STIX project.

    +

+

Note to TeX users

+

These fonts have been tested with both +XeTeX +and +luaTeX +with good results. For best results, XeTeX users will want to use +version 0.999992 or later of XeTeX, which ships with +TeXLive 2020. +This version fixes a number of bugs that were present in earlier +versions. Our thanks go out to Jonathan Kew and Khaled Hosny for +their generous help in identifying and fixing these bugs. LaTeX users +should also make sure they have the latest version of the +amsmath package.

+

Build instructions

+

After cloning the project, the fonts can be built using the build.sh script (use --verbose option for more detailed build log):

+
$ ./build.sh
+
+

This may take several minutes to complete. The first time the script is called, it will create a Python virtual environment that will be also used for subsequent builds. Each time the script is called, the fonts will be rebuilt from scratch. The built fonts will be in build subdirectory, and should be manually copied and committed to fonts subdirectory.

+

Notes on source formats and build process

+

The design masters for the STIX Two Text fonts are the .vfj files, a json source format used by FontLab 7. These files contain the glyph outlines, spacing, mark anchors, kerning and associated classes, font info, and variable design space info. Changes or additions to any of these things should be made in the .vfj files.

+

The build script used to generate font files uses the .ufo and .designspace files, not the .vfj sources directly. These files can be exported from FontLab 7 using the default export profile for ‘DesignSpace + UFO’.

+

The .ren files are glyph name management files used by the build script to manage the relationship of development names in the sources to the build names used in the post or CFF tables of the fonts.

+

Because of issues with editing and managing OpenType Layout GPOS in variable font sources, the OTL projects for the STIX Two Text fonts are built in Microsoft’s Visual OpenType Layout Tool (VOLT). This means changes to OTL, including updates to mark anchors and kerning implemented in the .vfj sources need to be passed through VOLT, updated in the .vtp VOLT project files, and compiled in .input.ttf which are then used by the build script as a source for the OTL tables in the fonts.

+

Obviously, any changes or extension to the glyph set in the .vfj design sources needs to be reflected in each of the other sources used in the build process: in the .ufo files, the .ren file glyph name lists, and especially in the .input.ttf files and .vtp project files. Fresh .input.ttf files can be exported from FontLab 7, opened in VOLT, and the .vtp project files imported and updated.

+

Note that if changes or updates are made to mark anchors or kerning or associated classes in the .vfj sources, these need to be converted to VOLT format and imported into the projects, replacing or updating existing VOLT lookups and groups. This can be done using the vfj-to-volt.py tool.

+

The revised .vtp files should then be exported for future use, and the .input.ttf fonts shipped from VOLT (this is important, because although the fonts will work if just compiled and saved in VOLT, they will contain private VOLT source tables and unregistered OTL features that will be then end up in the fonts generated by the build script; so use the ‘Ship Font’ option in VOLT and overwrite the .input.ttf file (save a copy with the VOLT project, if you like, but so long as you remembered to export the updated .vtp you can always reimport as needed)).

+

IMPORTANT : the STIXTwoMath-Regular.input.ttf file is also the source for the MATH table and cmap table in the final font build. Care must be taken to preserve or extend these as necessary in this file when updating OpenType Layout or other aspects of the font.

+

Once all the source files are ready, run the build.sh as described above. The build script describes what it is doing as it runs, and verbose mode can be used to get more detail. In overview, this is what it does:

+
    +
  1. Pre-process the UFO files to: +a) remove all features and kerning groups from the UFOs; b) rename the glyphs to match the TTFs (otherwise the binary tables can’t be grafted in with FontTools easily); c) extract the binary tables and add them under data/com.github.fonttools.ttx/ in the UFO font where ufo2ft expects them; d) save the modified files in build/masters to keep the sources unchanged.
    2. +
  2. Build variable font with fontmake from build/masters UFOs.
    3. +
  3. Build binary masters with fontmake (needed for the next step) from UFOs.
    4. +
  4. Build static fonts with fontmake from UFOs, but telling it to interpolate OTL tables from the binary masters.
    5. +
  5. Post-process the fonts to fix the name tables and other final touchups.

That means: +1. Identifying common Type3 fonts we encounter (Matplotlib, LaTeX, etc.). +2. Capturing their glyph outlines once, converting them to reusable TTF/OTF binaries. +3. At runtime, matching Type3 fonts in incoming PDFs against that library (by signature) so we can embed the canonical TTF instead of falling back to generic fonts. +4. Using the captured char-code sequences so regeneration and editing preserves glyphs even when original fonts had no ToUnicode map. + +## Current State +- **Extraction**: `PdfJsonTextElement` now stores raw Type3 char codes; `encodeTextWithFont` can use them so token-level rewrites keep original glyphs. +- **Regeneration**: Page regeneration now uses those char codes when writing new content streams, so existing text should remain visible even when tokens must be rebuilt. +- **Scripts**: `scripts/index_type3_catalogue.py` scans PDFs in `app/core/src/main/resources/type3/samples` with `pdffonts` and writes `catalogue.json` (basic list of Type3 fonts encountered). This is only the first step; we still need per-font signatures and converted binaries. +- **Samples**: There are sample PDFs under `app/core/src/main/resources/type3/samples/` (Matplotlib slides, etc.) that we can mine for common Type3 fonts. +- **Library matching**: `Type3FontLibrary` loads `type3/library/index.json`, and `Type3LibraryStrategy` injects the prebuilt TTF/OTF payloads straight into `PdfJsonFont` conversion candidates. At runtime this is now the *only* conversion path; if the library does not recognise a signature we fall back to the captured Type3 glyph codes instead of trying to synthesize a font on the fly. +- **Offline conversion helpers**: `scripts/type3_to_cff.py` is still available for developers who need to turn a Type3-only PDF into a reusable TTF/OTF, but it is no longer wired into the server lifecycle. Everything shipped to users must be backed by the curated library. +- **Signature CLI**: `Type3SignatureTool` (`./gradlew :proprietary:type3SignatureTool --args="--pdf sample.pdf --output meta.json --pretty"`) dumps every Type3 font in a PDF along with its signature + glyph coverage. Use this to extend `index.json` without touching the backend. +- **Signature inventory**: `docs/type3/signatures/` stores the captured dumps, and `scripts/summarize_type3_signatures.py` keeps `docs/type3/signature_inventory.md` up to date so we know which aliases still need binaries. + +## Remaining Work +1. **Signature capture tooling** + - ✅ `Type3SignatureTool` (`./gradlew :proprietary:type3SignatureTool`) dumps signature + glyph coverage JSON; keep them under `docs/type3/signatures`. + - ✅ `scripts/summarize_type3_signatures.py` produces `docs/type3/signature_inventory.md` to highlight remaining gaps. + - ✅ `scripts/harvest_type3_fonts.py --input ` bulk-processes entire PDF folders, reusing cached signature JSON files and writing `docs/type3/harvest_report.json` so you can keep adding new samples over time. + - ✅ `scripts/download_pdf_samples.py` downloads large batches of PDF URLs into a staging folder that can immediately be fed to the harvester. + - ⏱️ Extend `scripts/index_type3_catalogue.py` to read those dumps so the catalogue and library stay in sync. + +2. **Library coverage** + - ✅ Added CM (cmr10/cmmi10/cmex10/cmsy10), STIX Size Three symbols, and SourceCodePro (SauceCode) using upstream TTF/OTF payloads. + - 🔜 Add Matplotlib-only subsets (F36/F59). For proprietary Type3 shapes, use the offline FontTools helper (`scripts/type3_to_cff.py`) to generate TTF/OTF payloads, drop them under `type3/library/fonts//`, and reference them from `index.json`. + - Each entry in `type3/library/index.json` should contain `{id, aliases, signatures, glyphCoverage, program/web/pdf payloads, source PDF}`. + +3. **Glyph coverage metadata** + - ✅ When adding a library entry, copy the `glyphCoverage` array from the signature JSON so runtime preflight knows exactly which code points exist. The backend now consults this data while building new text runs so characters stay on the original Type3 font whenever it supports them. + +4. **Automation** + - ✅ `scripts/update_type3_library.py` ingests the captured signature JSON files, merges their signatures/aliases/glyph coverage into `app/core/src/main/resources/type3/library/index.json`, and reports any fonts that still lack entries. Run it with `--apply` after harvesting new samples. + +5. **Validation** + - 🔁 After each new library entry, run a JSON→PDF roundtrip on the source PDF to confirm edited text sticks with the canonical font (FontTools stays disabled unless the font is missing). + +## Tooling/Dependencies +- Requires `pdffonts` (poppler-utils) for the current indexing script. +- Optional: `scripts/type3_to_cff.py` (fontTools) when you need to manufacture a TTF/OTF for an otherwise Type3-only font before adding it to the library. +- Backend relies on PDFBox 3.x. + +## Library Onboarding Workflow +Follow this loop whenever you encounter a new Type3 face that is missing from the library: + +1. **Capture signatures** + Run `./gradlew :proprietary:type3SignatureTool --args="--pdf path/to/sample.pdf --output docs/type3/signatures/.json --pretty"` to dump the font’s signature, glyph coverage, and aliases. Commit the JSON under `docs/type3/signatures/`. + +2. **Harvest more samples (optional)** + Use `scripts/harvest_type3_fonts.py --input ` to bulk-run the signature tool across a directory of PDFs. This keeps `docs/type3/signature_inventory.md` fresh so you can see how often each alias appears. + +3. **Collect a canonical TTF/OTF** + - If the font is really just a subset of a known family (DejaVu, Computer Modern, STIX, etc.), copy the upstream TTF/OTF into `app/core/src/main/resources/type3/library/fonts//`. + - If no canonical binary exists, feed the sample PDF through `scripts/type3_to_cff.py --input glyphs.json --ttf-output ` to synthesize one offline. Review the glyphs visually before committing. + +4. **Update the library index** + Reference the binary from `app/core/src/main/resources/type3/library/index.json` (use the `resource` field so the build packs the raw TTF/OTF). Add the captured signatures, aliases, glyph coverage, and the PDF you mined as `source`. + +5. **Apply bulk edits automatically** + After dropping new signature dumps, run `scripts/update_type3_library.py --apply` to merge any missing signatures/aliases/coverage entries into `index.json`. The script prints a list of fonts that still lack binaries so you know what to tackle next. + +6. **Verify the round-trip** + Convert the sample PDF to JSON through the app, edit text to introduce new characters, and export it back to PDF. The logs should show `[TYPE3] Strategy type3-library finished with status SUCCESS`, and the output should keep the original styling even for the new glyphs. + +Because the server no longer attempts runtime synthesis, once a font lands in the library it will stay stable across every deployment. Missing fonts simply fall back to their Type3 glyph codes until you add them to the index, so there is always a deterministic path forward. + +## How to Use the Existing Script +``` +# From repo root +scripts/index_type3_catalogue.py \ + --samples app/core/src/main/resources/type3/samples \ + --output app/core/src/main/resources/type3/catalogue.json +``` +Output is a simple JSON array with `source`, `fontName`, and `encoding`. This needs to be extended with signatures and references to the converted TTFs once that tooling is in place. + +## Expected Outcomes +- A deduplicated library of the most common Type3 fonts we encounter, each with a stable signature and prebuilt TTF/OTF. +- Backend automatically matches a Type3 font to its library entry and embeds the canonical TTF during edit/export. +- Fallback font usage drops dramatically; edited PDFs retain the original look with Type3Synth fonts only used when genuinely necessary. +- Additional metrics (e.g., glyph coverage) stored in the catalogue so we can diagnose gaps quickly. + +## Next Steps Checklist +1. Capture signatures for every sample font and add them to `type3/library/index.json`. +2. Extend catalogue JSON to include signatures + metadata. +3. Batch-convert the remaining samples into the Type3 library (TTF/OTF files under `resources/type3/library/`). +4. Provide doc or script for adding new fonts to the library. +5. Run regression tests on sample PDFs to ensure original text remains visible and new text matches the Type3 font whenever possible. + +## Library Layout Cheat Sheet +- **Index**: `app/core/src/main/resources/type3/library/index.json`. +- **Font payloads**: drop TTF/OTF data under `type3/library/fonts//.ttf`. +- **Entry schema**: + ```json + { + "id": "unique-id", + "label": "Human readable name", + "signatures": ["sha256:..."], + "aliases": ["SubsetPrefix+RealName"], + "program": {"resource": "type3/library/fonts/family/font.otf", "format": "otf"}, + "webProgram": {"resource": "...", "format": "ttf"}, + "pdfProgram": {"resource": "...", "format": "ttf"}, + "glyphCoverage": [32,65,66], + "source": "Where the sample came from" + } + ``` +- **Runtime flow**: + 1. `Type3FontConversionService` builds a `Type3ConversionRequest`. + 2. `Type3LibraryStrategy` hashes the font via `Type3FontSignatureCalculator`. + 3. If the signature/alias exists in the index, it injects the canonical payload as a `PdfJsonFontConversionCandidate`. + 4. `PdfJsonConversionService` prefers conversion candidates over embedded Type3 programs when reloading fonts, so new text uses the canonical TTF automatically. + +### Signature Capture Tool +``` +# Dump all Type3 fonts in a PDF, their signatures, and glyph coverage +./gradlew :proprietary:type3SignatureTool \ + --args="--pdf app/core/src/main/resources/type3/samples/01_Matplotlib.pdf --output tmp/signatures.json --pretty" +``` +Use the resulting JSON to fill `signatures`, `aliases`, and `glyphCoverage` in `type3/library/index.json`.

This eliminates the `PDType3Font.encode` limitation and keeps edited text visually identical to the original Type3 output. diff --git a/frontend/package-lock.json b/frontend/package-lock.json index
