A Bézier curve is a parametric curve used in computer graphics and related fields. A set of discrete "control points" defines a smooth, continuous curve by means of a formula. Usually the curve is intended to approximate a real-world shape that otherwise has no mathematical representation or whose representation is unknown or too complicated. The Bézier curve is named after French engineer Pierre Bézier (1910–1999), who used it in the 1960s for designing curves for the bodywork of Renault cars. Other uses include the design of computer fonts and animation. Bézier curves can be combined to form a Bézier spline, or generalized to higher dimensions to form Bézier surfaces. The Bézier triangle is a special case of the latter.
PostScript (PS) is a page description language in the electronic publishing and desktop publishing realm. It is a dynamically typed, concatenative programming language. It was created at Adobe Systems by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton from 1982 to 1984.
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.
Vector graphics is a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. The associated mechanisms may include vector display and printing hardware, vector data models and file formats, as well as the software based on these data models. Vector graphics is an alternative to raster or bitmap graphics, with each having advantages and disadvantages in specific situations.
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.
In computer graphics, rasterisation or rasterization is the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image. The rasterized image may then be displayed on a computer display, video display or printer, or stored in a bitmap file format. Rasterization may refer to the technique of drawing 3D models, or the conversion of 2D rendering primitives such as polygons, line segments into a rasterized format.
Ghostscript is a suite of software based on an interpreter for Adobe Systems' PostScript and Portable Document Format (PDF) page description languages. Its main purposes are the rasterization or rendering of such page description language files, for the display or printing of document pages, and the conversion between PostScript and PDF files.
A typeface is a design of letters, numbers and other symbols, to be used in printing or for electronic display. Most typefaces include variations in size, weight, slope, width, and so on. Each of these variations of the typeface is a font.
Arial is a sans-serif typeface and set of computer fonts in the neo-grotesque style. Fonts from the Arial family are included with all versions of Microsoft Windows from Windows 3.1 on, some other Microsoft software applications, Apple's macOS and many PostScript 3 computer printers. The typeface was designed in 1982, by Robin Nicholas and Patricia Saunders, for Monotype Typography. Each of its characters has the same width as that character in the popular typeface Helvetica; the purpose of this design is to allow a document designed in Helvetica to be displayed and printed with the intended line-breaks and page-breaks without a Helvetica license. Because of their almost identical appearances, both Arial and Helvetica have commonly been mistaken for each other.
Courier is a monospaced slab serif typeface. The typeface was designed by Howard "Bud" Kettler (1919–1999). Initially created for IBM's typewriters, it has been adapted for use as a computer font, and versions of it are installed on most desktop computers.
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.
In computer graphics, image tracing, raster-to-vector conversion or raster vectorization is the conversion of raster graphics into vector graphics.
Font hinting is the use of mathematical instructions to adjust the display of an outline font so that it lines up with a rasterized grid. At low screen resolutions, hinting is critical for producing clear, legible text. It can be accompanied by antialiasing and subpixel rendering for further clarity.
Apple's Macintosh computer supports a wide variety of fonts. This support was one of the features that initially distinguished it from other systems.
Scantext was a professional code-driven digital typesetting system popular in the 1980s, rendered obsolete by the popularity of the personal computer and desktop publishing software. It was developed and built by Scangraphic, a division of Dr. Böger Duplomat Apparate GmbH & Co. KG, based in Wedel near Hamburg, Germany.
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.
Typefaces, fonts, and their glyphs raise intellectual property considerations in copyright, trademark, design patent, and related laws. The copyright status of a typeface and of any font file that describes it digitally varies between jurisdictions. In the United States, the shapes of typefaces are not eligible for copyright but may be protected by design patent. Typefaces can be protected in other countries, including the United Kingdom, Germany, and France, by industrial design protections that are similar to copyright or design patent in that they protect the abstract shapes. Additionally, in the US and some other countries, computer fonts, the digital instantiation of the shapes as vector outlines, may be protected by copyright on the computer code that produces them. The name of a typeface may also be protected as a trademark.
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.
URW Type Foundry GmbH is a type foundry based in Hamburg, Germany. The foundry has its own library with more than 500 font families. The company specializes in customized corporate typefaces and the development of non-Latin fonts. It has been owned by Monotype Imaging since May 2020.
Peter Karow is a German entrepreneur, inventor and software developer. He holds several patents in the field of desktop publishing and is known for his work on computer fonts. He contributed with several books and patents to the development of operating systems for computers. He is recognized as the inventor of outline computer fonts.
