A font editor is a class of application software specifically designed to create or modify font files. Font editors differ greatly depending on if they are designed to edit bitmap fonts or outline fonts. Most modern font editors deal with the outline fonts. Bitmap fonts uses an older technology and are most commonly used in console applications. The bitmap font editors were usually very specialized, as each computing platform had its own font format. One subcategory of bitmap fonts is text mode fonts.
The following editors use outline vector graphics to create font files in common formats.
TrueType is an outline font standard developed by Apple in the late 1980s as a competitor to Adobe's Type 1 fonts used in PostScript. It has become the most common format for fonts on the classic Mac OS, macOS, and Microsoft Windows operating systems.
Metafont is a description language used to define raster fonts. It is also the name of the interpreter that executes Metafont code, generating the bitmap fonts that can be embedded into e.g. PostScript. Metafont was devised by Donald Knuth as a companion to his TeX typesetting system.
OpenType is a format for scalable computer fonts. Derived from TrueType, it retains TrueType's basic structure but adds many intricate data structures for describing typographic behavior. OpenType is a registered trademark of Microsoft Corporation.
Dots per inch is a measure of spatial printing, video or image scanner dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm). Similarly, dots per centimetre refers to the number of individual dots that can be placed within a line of 1 centimetre (0.394 in).
Tahoma is a humanist sans-serif typeface that Matthew Carter designed for Microsoft Corporation. Microsoft first distributed it, along with Carter's Verdana, as a font with Office 97.
Fontographer is a font editor for Windows and macOS; it is used to create digital fonts. It was originally developed by Altsys but is now owned by FontLab Ltd.
A computer font is implemented as a digital data file containing a set of graphically related glyphs. A computer font is designed and created using a font editor. A computer font specifically designed for the computer screen, and not for printing, is a screen font.
There are Unicode typefaces which are open-source and designed to contain glyphs of all Unicode characters, or at least a broad selection of Unicode scripts. There are also numerous projects aimed at providing only a certain script, such as the Arabeyes Arabic font. The advantage of targeting only some scripts with a font was that certain Unicode characters should be rendered differently depending on which language they are used in, and that a font that only includes the characters a certain user needs will be much smaller in file size compared to one with many glyphs. Unicode fonts in modern formats such as OpenType can in theory cover multiple languages by including multiple glyphs per character, though very few actually cover more than one language's forms of the unified Han characters.
Microsoft PhotoDraw was a vector graphics and raster image editing software developed by Microsoft. It was released in 1999 as part of the Microsoft Office 2000 family of products and was specifically designed for creating and editing graphics, illustrations, and photo compositions.
FontForge is a FOSS font editor which supports many common font formats. Developed primarily by George Williams until 2012, FontForge is free software and is distributed under a mix of the GNU General Public License Version 3 and the 3-clause BSD license. It is available for operating systems including Linux, Windows, and macOS, and is localized into 12 languages.
A number of vector graphics editors exist for various platforms. Potential users of these editors will make a comparison of vector graphics editors based on factors such as the availability for the user's platform, the software license, the feature set, the merits of the user interface (UI) and the focus of the program. Some programs are more suitable for artistic work while others are better for technical drawings. Another important factor is the application's support of various vector and bitmap image formats for import and export.
Monaco is a monospaced sans-serif typeface designed by Susan Kare and Kris Holmes. It ships with macOS and was already present with all previous versions of the Mac operating system. Characters are distinct, and it is difficult to confuse 0 and O, or 1, |, I and l. A unique feature of the font is the high curvature of its parentheses as well as the width of its square brackets, the result of these being that an empty pair of parentheses or square brackets will strongly resemble a circle or square, respectively.
A Unicode font is a computer font that maps glyphs to code points defined in the Unicode Standard. The vast majority of modern computer fonts use Unicode mappings, even those fonts which only include glyphs for a single writing system, or even only support the basic Latin alphabet. Fonts which support a wide range of Unicode scripts and Unicode symbols are sometimes referred to as "pan-Unicode fonts", although as the maximum number of glyphs that can be defined in a TrueType font is restricted to 65,535, it is not possible for a single font to provide individual glyphs for all defined Unicode characters. This article lists some widely used Unicode fonts that support a comparatively large number and broad range of Unicode characters.
FontLab is a font editor developed by Fontlab Ltd., Inc. Since the early 2000s, it has been the dominant software tool for commercial/retail digital font development. FontLab is available for Windows and macOS.
Apple's Macintosh computer supports a wide variety of fonts. This support was one of the features that initially distinguished it from other systems.
PostScript fonts are font files encoded in outline font specifications developed by Adobe Systems for professional digital typesetting. This system uses PostScript file format to encode font information.
Bitstream Font Fusion is a small, fast, object-oriented font engine written in ANSI C capable of rendering high-quality text on any platform, any device, and at any resolution. The entire source code is portable, optimized, and executes independent of operating system and processor. The font engine is capable of rendering 2,400-3,300 characters per second on a 100 MIPS CPU.
Adobe Systems, Inc. v. Southern Software, Inc. was a case in the United States District Court for the Northern District of California regarding the copyrightability of digitized typefaces. The case is notable since typeface designs in general are not protected under United States copyright law, as determined in Eltra Corp. v. Ringer. Since that case, the United States Copyright Office has published policy decisions acknowledging the registration of computer programs that generate typefaces. In this case, the court held that Adobe's Utopia font was protectable under copyright and Southern Software, Inc.'s Veracity font was substantially similar and infringing.
Boxy SVG is a vector graphics editor for creating illustrations, as well as logos, icons, and other elements of graphic design. It is primarily focused on editing drawings in the SVG file format. The program is available as both a web app and a desktop application for Windows, macOS, ChromeOS, and Linux-based operating systems.
