In order to make this project usable to a vast majority of developers, we distribute it under two mutually exclusive open-source licenses. This means that *you* must choose *one* of the two licenses described below, then obey all its terms and conditions when using FreeType 2 in any of your projects or products. - The FreeType License, found in the file `docs/FTL.TXT`, which is similar to the original BSD license *with* an advertising clause that forces you to explicitly cite the FreeType project in your product's documentation. All details are in the license file. This license is suited to products which don't use the GNU General Public License. Note that this license is compatible to the GNU General Public License version 3, but not version 2. - The GNU General Public License version 2, found in `docs/GPLv2.TXT` (any later version can be used also), for programs which already use the GPL. Note that the FTL is incompatible with GPLv2 due to its advertisement clause. The contributed BDF and PCF drivers come with a license similar to that of the X Window System. It is compatible to the above two licenses (see files `src/bdf/README` and `src/pcf/README`). The same holds for the source code files `src/base/fthash.c` and `include/freetype/internal/fthash.h`; they were part of the BDF driver in earlier FreeType versions. The gzip module uses the zlib license (see `src/gzip/zlib.h`) which too is compatible to the above two licenses. The files `src/autofit/ft-hb-ft.c`, `src/autofit/ft-hb-decls.h`, `src/autofit/ft-hb-types.h`, and `src/autofit/hb-script-list.h` contain code taken (almost) verbatim from the HarfBuzz library, which uses the 'Old MIT' license compatible to the above two licenses. The MD5 checksum support (only used for debugging in development builds) is in the public domain. --- end of LICENSE.TXT --- ===== skia/third_party/externals/freetype/docs/FTL.TXT ===== The FreeType Project LICENSE ---------------------------- 2006-Jan-27 Copyright 1996-2002, 2006 by David Turner, Robert Wilhelm, and Werner Lemberg Introduction ============ The FreeType Project is distributed in several archive packages; some of them may contain, in addition to the FreeType font engine, various tools and contributions which rely on, or relate to, the FreeType Project. This license applies to all files found in such packages, and which do not fall under their own explicit license. The license affects thus the FreeType font engine, the test programs, documentation and makefiles, at the very least. This license was inspired by the BSD, Artistic, and IJG (Independent JPEG Group) licenses, which all encourage inclusion and use of free software in commercial and freeware products alike. As a consequence, its main points are that: o We don't promise that this software works. However, we will be interested in any kind of bug reports. (`as is' distribution) o You can use this software for whatever you want, in parts or full form, without having to pay us. (`royalty-free' usage) o You may not pretend that you wrote this software. If you use it, or only parts of it, in a program, you must acknowledge somewhere in your documentation that you have used the FreeType code. (`credits') We specifically permit and encourage the inclusion of this software, with or without modifications, in commercial products. We disclaim all warranties covering The FreeType Project and assume no liability related to The FreeType Project. Finally, many people asked us for a preferred form for a credit/disclaimer to use in compliance with this license. We thus encourage you to use the following text: """ Portions of this software are copyright © The FreeType Project (https://freetype.org). All rights reserved. """ Please replace with the value from the FreeType version you actually use. Legal Terms =========== 0. Definitions -------------- Throughout this license, the terms `package', `FreeType Project', and `FreeType archive' refer to the set of files originally distributed by the authors (David Turner, Robert Wilhelm, and Werner Lemberg) as the `FreeType Project', be they named as alpha, beta or final release. `You' refers to the licensee, or person using the project, where `using' is a generic term including compiling the project's source code as well as linking it to form a `program' or `executable'. This program is referred to as `a program using the FreeType engine'. This license applies to all files distributed in the original FreeType Project, including all source code, binaries and documentation, unless otherwise stated in the file in its original, unmodified form as distributed in the original archive. If you are unsure whether or not a particular file is covered by this license, you must contact us to verify this. The FreeType Project is copyright (C) 1996-2000 by David Turner, Robert Wilhelm, and Werner Lemberg. All rights reserved except as specified below. 1. No Warranty -------------- THE FREETYPE PROJECT IS PROVIDED `AS IS' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE OR THE INABILITY TO USE, OF THE FREETYPE PROJECT. 2. Redistribution ----------------- This license grants a worldwide, royalty-free, perpetual and irrevocable right and license to use, execute, perform, compile, display, copy, create derivative works of, distribute and sublicense the FreeType Project (in both source and object code forms) and derivative works thereof for any purpose; and to authorize others to exercise some or all of the rights granted herein, subject to the following conditions: o Redistribution of source code must retain this license file (`FTL.TXT') unaltered; any additions, deletions or changes to the original files must be clearly indicated in accompanying documentation. The copyright notices of the unaltered, original files must be preserved in all copies of source files. o Redistribution in binary form must provide a disclaimer that states that the software is based in part of the work of the FreeType Team, in the distribution documentation. We also encourage you to put an URL to the FreeType web page in your documentation, though this isn't mandatory. These conditions apply to any software derived from or based on the FreeType Project, not just the unmodified files. If you use our work, you must acknowledge us. However, no fee need be paid to us. 3. Advertising -------------- Neither the FreeType authors and contributors nor you shall use the name of the other for commercial, advertising, or promotional purposes without specific prior written permission. We suggest, but do not require, that you use one or more of the following phrases to refer to this software in your documentation or advertising materials: `FreeType Project', `FreeType Engine', `FreeType library', or `FreeType Distribution'. As you have not signed this license, you are not required to accept it. However, as the FreeType Project is copyrighted material, only this license, or another one contracted with the authors, grants you the right to use, distribute, and modify it. Therefore, by using, distributing, or modifying the FreeType Project, you indicate that you understand and accept all the terms of this license. 4. Contacts ----------- There are two mailing lists related to FreeType: o freetype@nongnu.org Discusses general use and applications of FreeType, as well as future and wanted additions to the library and distribution. If you are looking for support, start in this list if you haven't found anything to help you in the documentation. o freetype-devel@nongnu.org Discusses bugs, as well as engine internals, design issues, specific licenses, porting, etc. Our home page can be found at https://freetype.org --- end of FTL.TXT --- ===== skia/third_party/externals/harfbuzz/COPYING ===== HarfBuzz is licensed under the so-called "Old MIT" license.

Note that the libjpeg-turbo SIMD source code bears the [zlib License](https://opensource.org/licenses/Zlib), but in the context of the overall libjpeg API library, the terms of the zlib License are subsumed by the terms of the IJG License. - The Modified (3-clause) BSD License, which is listed below This license applies to the TurboJPEG API library and associated programs, as well as the build system. Note that the TurboJPEG API library wraps the libjpeg API library, so in the context of the overall TurboJPEG API library, both the terms of the IJG License and the terms of the Modified (3-clause) BSD License apply. Complying with the libjpeg-turbo Licenses ========================================= This section provides a roll-up of the libjpeg-turbo licensing terms, to the best of our understanding. This is not a license in and of itself. It is intended solely for clarification. 1. If you are distributing a modified version of the libjpeg-turbo source, then: 1. You cannot alter or remove any existing copyright or license notices from the source. **Origin** - Clause 1 of the IJG License - Clause 1 of the Modified BSD License - Clauses 1 and 3 of the zlib License 2. You must add your own copyright notice to the header of each source file you modified, so others can tell that you modified that file. (If there is not an existing copyright header in that file, then you can simply add a notice stating that you modified the file.) **Origin** - Clause 1 of the IJG License - Clause 2 of the zlib License 3. You must include the IJG README file, and you must not alter any of the copyright or license text in that file. **Origin** - Clause 1 of the IJG License 2. If you are distributing only libjpeg-turbo binaries without the source, or if you are distributing an application that statically links with libjpeg-turbo, then: 1. Your product documentation must include a message stating: This software is based in part on the work of the Independent JPEG Group. **Origin** - Clause 2 of the IJG license 2. If your binary distribution includes or uses the TurboJPEG API, then your product documentation must include the text of the Modified BSD License (see below.) **Origin** - Clause 2 of the Modified BSD License 3. You cannot use the name of the IJG or The libjpeg-turbo Project or the contributors thereof in advertising, publicity, etc. **Origin** - IJG License - Clause 3 of the Modified BSD License 4. The IJG and The libjpeg-turbo Project do not warrant libjpeg-turbo to be free of defects, nor do we accept any liability for undesirable consequences resulting from your use of the software. **Origin** - IJG License - Modified BSD License - zlib License The Modified (3-clause) BSD License =================================== Copyright (C)2009-2024 D.

Why Two Licenses? ================= The zlib License could have been used instead of the Modified (3-clause) BSD License, and since the IJG License effectively subsumes the distribution conditions of the zlib License, this would have effectively placed libjpeg-turbo binary distributions under the IJG License. However, the IJG License specifically refers to the Independent JPEG Group and does not extend attribution and endorsement protections to other entities. Thus, it was desirable to choose a license that granted us the same protections for new code that were granted to the IJG for code derived from their software. ===== skia/third_party/externals/libjpeg-turbo/README.ijg ===== libjpeg-turbo note: This file has been modified by The libjpeg-turbo Project to include only information relevant to libjpeg-turbo, to wordsmith certain sections, and to remove impolitic language that existed in the libjpeg v8 README. It is included only for reference. Please see README.md for information specific to libjpeg-turbo.

If you want to understand how the JPEG code works, we suggest reading one or more of the REFERENCES, then looking at the documentation files (in roughly the order listed) before diving into the code. OVERVIEW ======== This package contains C software to implement JPEG image encoding, decoding, and transcoding. JPEG (pronounced "jay-peg") is a standardized compression method for full-color and grayscale images. JPEG's strong suit is compressing photographic images or other types of images that have smooth color and brightness transitions between neighboring pixels. Images with sharp lines or other abrupt features may not compress well with JPEG, and a higher JPEG quality may have to be used to avoid visible compression artifacts with such images. JPEG is normally lossy, meaning that the output pixels are not necessarily identical to the input pixels. However, on photographic content and other "smooth" images, very good compression ratios can be obtained with no visible compression artifacts, and extremely high compression ratios are possible if you are willing to sacrifice image quality (by reducing the "quality" setting in the compressor.) This software implements JPEG baseline, extended-sequential, progressive, and lossless compression processes. Provision is made for supporting all variants of these processes, although some uncommon parameter settings aren't implemented yet. We have made no provision for supporting the hierarchical processes defined in the standard. We provide a set of library routines for reading and writing JPEG image files, plus two sample applications "cjpeg" and "djpeg", which use the library to perform conversion between JPEG and some other popular image file formats. The library is intended to be reused in other applications. In order to support file conversion and viewing software, we have included considerable functionality beyond the bare JPEG coding/decoding capability; for example, the color quantization modules are not strictly part of JPEG decoding, but they are essential for output to colormapped file formats. These extra functions can be compiled out of the library if not required for a particular application. We have also included "jpegtran", a utility for lossless transcoding between different JPEG processes, and "rdjpgcom" and "wrjpgcom", two simple applications for inserting and extracting textual comments in JFIF files. The emphasis in designing this software has been on achieving portability and flexibility, while also making it fast enough to be useful. In particular, the software is not intended to be read as a tutorial on JPEG. (See the REFERENCES section for introductory material.) Rather, it is intended to be reliable, portable, industrial-strength code. We do not claim to have achieved that goal in every aspect of the software, but we strive for it. We welcome the use of this software as a component of commercial products. No royalty is required, but we do ask for an acknowledgement in product documentation, as described under LEGAL ISSUES.

REFERENCES ========== We recommend reading one or more of these references before trying to understand the innards of the JPEG software. The best short technical introduction to the JPEG compression algorithm is Wallace, Gregory K. "The JPEG Still Picture Compression Standard", Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44. (Adjacent articles in that issue discuss MPEG motion picture compression, applications of JPEG, and related topics.) If you don't have the CACM issue handy, a PDF file containing a revised version of Wallace's article is available at http://www.ijg.org/files/Wallace.JPEG.pdf. The file (actually a preprint for an article that appeared in IEEE Trans. Consumer Electronics) omits the sample images that appeared in CACM, but it includes corrections and some added material. Note: the Wallace article is copyright ACM and IEEE, and it may not be used for commercial purposes. A somewhat less technical, more leisurely introduction to JPEG can be found in "The Data Compression Book" by Mark Nelson and Jean-loup Gailly, published by M&T Books (New York), 2nd ed. 1996, ISBN 1-55851-434-1. This book provides good explanations and example C code for a multitude of compression methods including JPEG. It is an excellent source if you are comfortable reading C code but don't know much about data compression in general. The book's JPEG sample code is far from industrial-strength, but when you are ready to look at a full implementation, you've got one here... The best currently available description of JPEG is the textbook "JPEG Still Image Data Compression Standard" by William B. Pennebaker and Joan L. Mitchell, published by Van Nostrand Reinhold, 1993, ISBN 0-442-01272-1. Price US$59.95, 638 pp. The book includes the complete text of the ISO JPEG standards (DIS 10918-1 and draft DIS 10918-2). The original JPEG standard is divided into two parts, Part 1 being the actual specification, while Part 2 covers compliance testing methods. Part 1 is titled "Digital Compression and Coding of Continuous-tone Still Images, Part 1: Requirements and guidelines" and has document numbers ISO/IEC IS 10918-1, ITU-T T.81. Part 2 is titled "Digital Compression and Coding of Continuous-tone Still Images, Part 2: Compliance testing" and has document numbers ISO/IEC IS 10918-2, ITU-T T.83. The JPEG standard does not specify all details of an interchangeable file format. For the omitted details, we follow the "JFIF" conventions, revision 1.02. JFIF version 1 has been adopted as ISO/IEC 10918-5 (05/2013) and Recommendation ITU-T T.871 (05/2011): Information technology - Digital compression and coding of continuous-tone still images: JPEG File Interchange Format (JFIF). It is available as a free download in PDF file format from https://www.iso.org/standard/54989.html and http://www.itu.int/rec/T-REC-T.871. A PDF file of the older JFIF 1.02 specification is available at http://www.w3.org/Graphics/JPEG/jfif3.pdf. The TIFF 6.0 file format specification can be obtained from http://mirrors.ctan.org/graphics/tiff/TIFF6.ps.gz. The JPEG incorporation scheme found in the TIFF 6.0 spec of 3-June-92 has a number of serious problems. IJG does not recommend use of the TIFF 6.0 design (TIFF Compression tag 6). Instead, we recommend the JPEG design proposed by TIFF Technical Note #2 (Compression tag 7). Copies of this Note can be obtained from http://www.ijg.org/files/. It is expected that the next revision of the TIFF spec will replace the 6.0 JPEG design with the Note's design. Although IJG's own code does not support TIFF/JPEG, the free libtiff library uses our library to implement TIFF/JPEG per the Note. ARCHIVE LOCATIONS ================= The "official" archive site for this software is www.ijg.org. The most recent released version can always be found there in directory "files". The JPEG FAQ (Frequently Asked Questions) article is a source of some general information about JPEG. It is available at http://www.faqs.org/faqs/jpeg-faq. FILE FORMAT COMPATIBILITY ========================= This software implements ITU T.81 | ISO/IEC 10918 with some extensions from ITU T.871 | ISO/IEC 10918-5 (JPEG File Interchange Format-- see REFERENCES). Informally, the term "JPEG image" or "JPEG file" most often refers to JFIF or a subset thereof, but there are other formats containing the name "JPEG" that are incompatible with the original JPEG standard or with JFIF (for instance, JPEG 2000 and JPEG XR). This software therefore does not support these formats. Indeed, one of the original reasons for developing this free software was to help force convergence on a common, interoperable format standard for JPEG files. JFIF is a minimal or "low end" representation. TIFF/JPEG (TIFF revision 6.0 as modified by TIFF Technical Note #2) can be used for "high end" applications that need to record a lot of additional data about an image.

Source: https://github.com/foliojs/fontkit/tree/v2.0.4 . Per-package license texts and original package manifests are included in the corresponding directories. Fontkit, dfa and brotli npm packages declare MIT in package.json; their upstream README files and manifests are preserved. `vendor/woff2.js` is the decompression-only WebAssembly distribution from wawoff2 2.0.1 (MIT, Copyright 2013–2017 the WOFF2 Authors). The wrapper is adapted for ES modules and browser/Node portability; the embedded reference WOFF2 decoder bytecode is unchanged. Source: https://github.com/fontello/wawoff2 . The WOFF2 license is included in `font-engine-third-party/wawoff2/LICENSE`. `RobotoFlex-Variable.woff2` is the Latin weight-axis subset distributed by @fontsource-variable/roboto-flex 5.2.8, under the SIL Open Font License 1.1. Its complete license appears in `RobotoFlex-OFL.txt`. All other small font fixtures are original synthetic fonts created using the build script in `tests/fixtures/create-fixtures.py`, under this project's MIT license. `vendor/font-instance.js` embeds the unchanged standalone HarfBuzz subsetter WebAssembly from harfbuzzjs 0.10.3. The local wrapper adapts byte ownership and axis pinning to ES modules. The original MIT license and build/export provenance are included under `harfbuzzjs/`. This version was retained after the supplied CFF2/HVAR regression fixture failed with a newer tested subsetter distribution. ===== dist/licenses/Pako-LICENSE.txt ===== (The MIT License) Copyright (C) 2014-2017 by Vitaly Puzrin and Andrei Tuputcyn Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

This license is copied below, and is also available with a FAQ at: http://scripts.sil.org/OFL ----------------------------------------------------------- SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007 ----------------------------------------------------------- PREAMBLE The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others. The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives. DEFINITIONS "Font Software" refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. This may include source files, build scripts and documentation. "Reserved Font Name" refers to any names specified as such after the copyright statement(s). "Original Version" refers to the collection of Font Software components as distributed by the Copyright Holder(s). "Modified Version" refers to any derivative made by adding to, deleting, or substituting -- in part or in whole -- any of the components of the Original Version, by changing formats or by porting the Font Software to a new environment. "Author" refers to any designer, engineer, programmer, technical writer or other person who contributed to the Font Software. PERMISSION & CONDITIONS Permission is hereby granted, free of charge, to any person obtaining a copy of the Font Software, to use, study, copy, merge, embed, modify, redistribute, and sell modified and unmodified copies of the Font Software, subject to the following conditions: 1) Neither the Font Software nor any of its individual components, in Original or Modified Versions, may be sold by itself. 2) Original or Modified Versions of the Font Software may be bundled, redistributed and/or sold with any software, provided that each copy contains the above copyright notice and this license. These can be included either as stand-alone text files, human-readable headers or in the appropriate machine-readable metadata fields within text or binary files as long as those fields can be easily viewed by the user. 3) No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit written permission is granted by the corresponding Copyright Holder. This restriction only applies to the primary font name as presented to the users. 4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software shall not be used to promote, endorse or advertise any Modified Version, except to acknowledge the contribution(s) of the Copyright Holder(s) and the Author(s) or with their explicit written permission. 5) The Font Software, modified or unmodified, in part or in whole, must be distributed entirely under this license, and must not be distributed under any other license. The requirement for fonts to remain under this license does not apply to any document created using the Font Software.

The symbols defined in the machine are Unicode character categories which could be mapped from code points. Machine definition: ```coffeescript # define symbols X = 0; # Other character L = 1; # Leading consonant V = 2; # Medial vowel T = 3; # Trailing consonant LV = 4; # Composed syllable LVT = 5; # Composed syllable M = 6; # Tone mark # define variables decomposed = L V T?; partial = LV T?; composed = LVT; # define main state machine pattern main = (decomposed | partial | composed) M?; ``` Visualized, the machine looks like this (double circles are accepting states): ![dfa](https://cloud.githubusercontent.com/assets/19409/19143719/8fbc6a12-8b5a-11e6-868d-99621644d094.png) Compiling and using the machine: ```javascript import compile from 'dfa/compile'; import fs from 'fs'; let stateMachine = compile(fs.readFileSync('hangul.machine', 'utf8')); // find matches for (let [startIndex, endIndex] of stateMachine.match([0, 1, 2, 3, 0, 4, 6]) { console.log('match:', startIndex, endIndex); } ``` Output: ``` match: 1 3 match: 5 6 ``` ## Syntax A state machine file contains a list of assignment statements.

Assigning a variable to a number produces a symbol, which is added to the state machine's alphabet. Assigning a variable to an expression allows for substitutions into later expressions. The special `main` variable should always be assigned to at the end of the file, and is the final expression that will be compiled. A subset of common regular expression syntax is supported. A list of operators and their precedence is below. Operators with the same precedence are evaluated left to right. | Precedence | Syntax | Type | Meaning | | ---------- | ---------- | --------------| ------------------------------------------ | | 1 | `a \| b` | Alternation | Matches either `a` or `b` | | 2 | `a b` | Concatenation | Matches `a` followed by `b` | | 3 | `a*` | Repetition | Matches zero or more occurrences of `a` | | 3 | `a+` | Repetition | Matches one ore more occurrences of `a` | | 3 | `a?` | Optional | Matches zero or one occurrence of `a` | | 3 | `a{n}` | Repetition | Matches exactly n occurrences of `a` | | 3 | `a{n,}` | Repetition | Matches n or more occurrences of `a` | | 3 | `a{,n}` | Repetition | Matches up to n occurrences of `a` | | 3 | `a{n,m}` | Repetition | Matches n to m occurrences of `a` | | 4 | `t:` | Tag | Tags the following expression with tag `t` | | 5 | `()` | Grouping | Groups an expression | ## License MIT ===== dist/licenses/font-engine-third-party/fast-deep-equal/LICENSE ===== MIT License Copyright (c) 2017 Evgeny Poberezkin Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

It supports many font formats, advanced glyph substitution and layout features, glyph path extraction, color emoji glyphs, font subsetting, and more. ## Features * Supports TrueType (.ttf), OpenType (.otf), WOFF, WOFF2, TrueType Collection (.ttc), and Datafork TrueType (.dfont) font files * Supports mapping characters to glyphs, including support for ligatures and other advanced substitutions (see below) * Supports reading glyph metrics and laying out glyphs, including support for kerning and other advanced layout features (see below) * Advanced OpenType features including glyph substitution (GSUB) and positioning (GPOS) * Apple Advanced Typography (AAT) glyph substitution features (morx table) * Support for getting glyph vector paths and converting them to SVG paths, or rendering them to a graphics context * Supports TrueType (glyf) and PostScript (CFF) outlines * Support for color glyphs (e.g. emoji), including Apple’s SBIX table, and Microsoft’s COLR table * Support for AAT variation glyphs, allowing for nearly infinite design control over weight, width, and other axes. * Font subsetting support - create a new font including only the specified glyphs ## Installation npm install fontkit ## Example ```javascript var fontkit = require('fontkit'); // open a font synchronously var font = fontkit.openSync('font.ttf'); // layout a string, using default shaping features. // returns a GlyphRun, describing glyphs and positions. var run = font.layout('hello world!'); // get an SVG path for a glyph var svg = run.glyphs[0].path.toSVG(); // create a font subset var subset = font.createSubset(); run.glyphs.forEach(function(glyph) { subset.includeGlyph(glyph); }); let buffer = subset.encode(); ``` ## API ### `fontkit.open(filename, postscriptName = null)` Opens a font file asynchronously, and returns a `Promise` with a font object. For collection fonts (such as TrueType collection files), you can pass a `postscriptName` to get that font out of the collection instead of a collection object. ### `fontkit.openSync(filename, postscriptName = null)` Opens a font file synchronously, and returns a font object. For collection fonts (such as TrueType collection files), you can pass a `postscriptName` to get that font out of the collection instead of a collection object. ### `fontkit.create(buffer, postscriptName = null)` Returns a font object for the given buffer. For collection fonts (such as TrueType collection files), you can pass a `postscriptName` to get that font out of the collection instead of a collection object. ## Font objects There are several different types of font objects that are returned by fontkit depending on the font format. They all inherit from the `TTFFont` class and have the same public API, described below. ### Metadata properties The following properties are strings (or null if the font does not contain strings for them) describing the font, as specified by the font creator. * `postscriptName` * `fullName` * `familyName` * `subfamilyName` * `copyright` * `version` ### Metrics The following properties describe the general metrics of the font. See [here](http://www.freetype.org/freetype2/docs/glyphs/glyphs-3.html) for a good overview of how all of these properties relate to one another. * `unitsPerEm` - the size of the font’s internal coordinate grid * `ascent` - the font’s [ascender](http://en.wikipedia.org/wiki/Ascender_(typography)) * `descent` - the font’s [descender](http://en.wikipedia.org/wiki/Descender) * `lineGap` - the amount of space that should be included between lines * `underlinePosition` - the offset from the normal underline position that should be used * `underlineThickness` - the weight of the underline that should be used * `italicAngle` - if this is an italic font, the angle the cursor should be drawn at to match the font design * `capHeight` - the height of capital letters above the baseline. See [here](http://en.wikipedia.org/wiki/Cap_height) for more details. * `xHeight`- the height of lower case letters. See [here](http://en.wikipedia.org/wiki/X-height) for more details. * `bbox` - the font’s bounding box, i.e. the box that encloses all glyphs in the font ### Other properties * `numGlyphs` - the number of glyphs in the font * `characterSet` - an array of all of the unicode code points supported by the font * `availableFeatures` - an array of all [OpenType feature tags](https://www.microsoft.com/typography/otspec/featuretags.htm) (or mapped AAT tags) supported by the font (see below for a description of this) ### Character to glyph mapping Fontkit includes several methods for character to glyph mapping, including support for advanced OpenType and AAT substitutions. #### `font.glyphForCodePoint(codePoint)` Maps a single unicode code point (number) to a Glyph object. Does not perform any advanced substitutions (there is no context to do so). #### `font.hasGlyphForCodePoint(codePoint)` Returns whether there is glyph in the font for the given unicode code point. #### `font.glyphsForString(string)` This method returns an array of Glyph objects for the given string. This is only a one-to-one mapping from characters to glyphs. For most uses, you should use `font.layout` (described below), which provides a much more advanced mapping supporting AAT and OpenType shaping. ### Glyph metrics and layout Fontkit includes several methods for accessing glyph metrics and performing layout, including support for kerning and other advanced OpenType positioning adjustments. #### `font.widthOfGlyph(glyph_id)` Returns the advance width (described above) for a single glyph id. #### `font.layout(string, features = [] | {})` This method returns a `GlyphRun` object, which includes an array of `Glyph`s and `GlyphPosition`s for the given string. `Glyph` objects are described below. `GlyphPosition` objects include 4 properties: `xAdvance`, `yAdvance`, `xOffset`, and `yOffset`. The `features` parameter is either an array of [OpenType feature tags](https://www.microsoft.com/typography/otspec/featuretags.htm) to be applied in addition to the default set, or an object mapping OpenType features to a boolean enabling or disabling each. If this is an AAT font, the OpenType feature tags are mapped to AAT features. ### Variation fonts Fontkit has support for AAT variation fonts, where glyphs can adjust their shape according to user defined settings along various axes including weight, width, and slant. Font designers specify the minimum, default, and maximum values for each axis they support, and allow the user fine grained control over the rendered text. #### `font.variationAxes` Returns an object describing the available variation axes. Keys are 4 letter axis tags, and values include `name`, `min`, `default`, and `max` properties for the axis. #### `font.namedVariations` The font designer may have picked out some variations that they think look particularly good, for example a light, regular, and bold weight which would traditionally be separate fonts. This property returns an object describing these named variation instances that the designer has specified. Keys are variation names, and values are objects with axis settings. #### `font.getVariation(variation)` Returns a new font object representing this variation, from which you can get glyphs and perform layout as normal. The `variation` parameter can either be a variation settings object or a string variation name. Variation settings objects have axis names as keys, and numbers as values (should be in the range specified by `font.variationAxes`). ### Other methods #### `font.getGlyph(glyph_id, codePoints = [])` Returns a glyph object for the given glyph id. You can pass the array of code points this glyph represents for your use later, and it will be stored in the glyph object. #### `font.createSubset()` Returns a Subset object for this font, described below. ## Font Collection objects For font collection files that contain multiple fonts in a single file, such as TrueType Collection (.ttc) and Datafork TrueType (.dfont) files, a font collection object can be returned by Fontkit. ### `collection.getFont(postscriptName)` Gets a font from the collection by its postscript name. Returns a Font object, described above. ### `collection.fonts` This property is a lazily-loaded array of all of the fonts in the collection. ## Glyph objects Glyph objects represent a glyph in the font. They have various properties for accessing metrics and the actual vector path the glyph represents, and methods for rendering the glyph to a graphics context. You do not create glyph objects directly. They are created by various methods on the font object, described above. There are several subclasses of the base `Glyph` class internally that may be returned depending on the font format, but they all include the following API. ### Properties * `id` - the glyph id in the font * `name` - the glyph name in the font * `codePoints` - an array of unicode code points that are represented by this glyph. There can be multiple code points in the case of ligatures and other glyphs that represent multiple visual characters. * `path` - a vector Path object representing the glyph * `bbox` - the glyph’s bounding box, i.e. the rectangle that encloses the glyph outline as tightly as possible. * `cbox` - the glyph’s control box. This is often the same as the bounding box, but is faster to compute. Because of the way bezier curves are defined, some of the control points can be outside of the bounding box. Where `bbox` takes this into account, `cbox` does not. Thus, `cbox` is less accurate, but faster to compute. See [here](http://www.freetype.org/freetype2/docs/glyphs/glyphs-6.html#section-2) for a more detailed description. * `advanceWidth` - the glyph’s advance width. ### `glyph.render(ctx, size)` Renders the glyph to the given graphics context, at the specified font size. ### Color glyphs (e.g. emoji) Fontkit has support for several different color emoji font formats. Currently, these include Apple’s SBIX table (as used by the “Apple Color Emoji” font), and Microsoft’s COLR table (supported by Windows 8.1). [Here](http://blog.symbolset.com/multicolor-fonts) is an overview of the various color font formats out there. #### `glyph.getImageForSize(size)` For SBIX glyphs, which are bitmap based, this returns an object containing some properties about the image, along with the image data itself (usually PNG). #### `glyph.layers` For COLR glyphs, which are vector based, this returns an array of objects representing the glyphs and colors for each layer in render order. ## Path objects Path objects are returned by glyphs and represent the actual vector outlines for each glyph in the font. Paths can be converted to SVG path data strings, or to functions that can be applied to render the path to a graphics context. ### `path.moveTo(x, y)` Moves the virtual pen to the given x, y coordinates. ### `path.lineTo(x, y)` Adds a line to the path from the current point to the given x, y coordinates. ### `path.quadraticCurveTo(cpx, cpy, x, y)` Adds a quadratic curve to the path from the current point to the given x, y coordinates using cpx, cpy as a control point. ### `path.bezierCurveTo(cp1x, cp1y, cp2x, cp2y, x, y)` Adds a bezier curve to the path from the current point to the given x, y coordinates using cp1x, cp1y and cp2x, cp2y as control points. ### `path.closePath()` Closes the current sub-path by drawing a straight line back to the starting point. ### `path.toFunction()` Compiles the path to a JavaScript function that can be applied with a graphics context in order to render the path. ### `path.toSVG()` Converts the path to an SVG path data string. ### `path.bbox` This property represents the path’s bounding box, i.e. the smallest rectangle that contains the entire path shape. This is the exact bounding box, taking into account control points that may be outside the visible shape. ### `path.cbox` This property represents the path’s control box. It is like the bounding box, but it includes all points of the path, including control points of bezier segments. It is much faster to compute than the real bounding box, but less accurate if there are control points outside of the visible shape. ## Subsets Fontkit can perform font subsetting, i.e. the process of creating a new font from an existing font where only the specified glyphs are included. This is useful to reduce the size of large fonts, such as in PDF generation or for web use. Currently, subsets produce minimal fonts designed for PDF embedding that may not work as standalone files. They have no cmap tables and other essential tables for standalone use. This limitation will be removed in the future. You create a Subset object by calling `font.createSubset()`, described above. The API on Subset objects is as follows. ### `subset.includeGlyph(glyph)` Includes the given glyph object or glyph ID in the subset. ### `subset.encode()` Returns a `Uint8Array` containing the encoded font file. ## License MIT ===== dist/licenses/font-engine-third-party/restructure/LICENSE ===== MIT License Copyright (c) 2015-present Devon Govett Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

Install emscripten 2. `make` ## Testing 1. `make test` ## Download Download from the [releases tab](https://github.com/harfbuzz/harfbuzzjs/releases). ## Usage ### TL;DR ```javascript require("harfbuzzjs").then(function (hb) { fetch('myfont.ttf').then(function (data) { return data.arrayBuffer(); }).then(function (fontdata) { var blob = hb.createBlob(fontdata); // Load the font data into something Harfbuzz can use var face = hb.createFace(blob, 0); // Select the first font in the file (there's normally only one!) var font = hb.createFont(face); // Create a Harfbuzz font object from the face var buffer = hb.createBuffer(); // Make a buffer to hold some text buffer.addText('abc'); // Fill it with some stuff buffer.guessSegmentProperties(); // Set script, language and direction hb.shape(font, buffer); // Shape the text, determining glyph IDs and positions var output = buffer.json(); // Enumerate the glyphs var xCursor = 0; var yCursor = 0; for (var glyph of output) { var glyphId = glyph.g; var xAdvance = glyph.ax; var xDisplacement = glyph.dx; var yDisplacement = glyph.dy; var svgPath = font.glyphToPath(glyphId); // You need to supply this bit drawAGlyph(svgPath, xCursor + xDisplacement, yDisplacement); xCursor += xAdvance; yCursor += yAdvance; } // Release memory buffer.destroy(); font.destroy(); face.destroy(); blob.destroy(); }) }) ``` More examples: ### Browser 1. `npx pad.js` 2. Open `http://127.0.0.1/examples/hbjs.example.html` or `http://127.0.0.1/examples/nohbjs.html` ### Node.js 1. `(cd examples && node hbjs.example.node.js)` We provide a wrapper (`hbjs.js`) around the main functionality of harfbuzz, but it's also easy to use other parts. (See `example/nohbjs.js` as an example. However, you may need a custom build to expose additional functionality.) ## [npm](https://www.npmjs.com/package/harfbuzzjs) Can be added with `npm i harfbuzzjs` or `yarn add harfbuzzjs`, see the examples for how to use it. ## Need more of the library? harfbuzzjs uses a stripped-down version of Harfbuzz generated by compiling Harfbuzz with `-DHB_TINY`. This may mean that some functions you need are not available. Look at `src/hb-config.hh` in the Harfbuzz source directory to see what has been removed. For example, `HB_TINY` defines `HB_LEAN` which (amongst other things) defines `HB_NO_OT_GLYPH_NAMES`. If, for example, you really need to get at the glyph names: 1. First, undefine the macro in question, by adding e.g. `#undef HB_NO_OT_GLYPH_NAMES` to `config-override.h`. 2. Next, export any function that you need by adding a line to `hbjs.symbols`; in this case `_hb_ot_get_glyph_name`. 3. Now the function will be exported through the WASM object, but you need to add Javascript to bridge to it - in this case, handling the memory allocation of the `char *` parameter `name` and marshalling it to a JavaScript string with `heapu8.subarray`. The best way to do this is to look at `hbjs.js` for functions which use similar signatures. If you have extended harfbuzzjs in ways that you think others will also benefit from, please raise a pull request. If there are parts of Harfbuzz that you need but the instructions above don't work, describe what you are trying to do in an issue. ## Using the library in a bigger emscripten project? See [harfbuzz port inside emscripten](https://github.com/emscripten-core/emscripten/blob/master/tools/ports/harfbuzz.py) and [emscripten-ports/HarfBuzz](https://github.com/emscripten-ports/HarfBuzz), basically all you need is to use `-s USE_HARFBUZZ=1` in your build. ## binaryen Optionally you can install `binaryen` and use `wasm-opt` like: ``` wasm-opt -Oz hb.wasm -o hb.wasm ``` `binaryen` also provides `wasm-dis` which can be used for, ``` wasm-dis hb.wasm | grep export wasm-dis hb.wasm | grep import ``` with that you can check if the built wasm file only exports things you need and doesn't need to import anything, as usual with wasm files built here.
