Font
A font is a set of glyphs (images) representing the characters from a particular character set in a particular typeface. In professional typography the term typeface is not interchangeable with the word font, which is defined as a given alphabet and its associated characters in a single size. For example, 8-point Caslon is one font, and 10-point Caslon is another. Historically, fonts came in specific sizes determining the size of characters, and in quantities of sorts or number of each letter provided. The design of characters in a font took into account all these factors.
As the range of typeface designs increased and requirements of publishers broadened over the centuries, fonts of specific weight (blackness or lightness) and stylistic variants—most commonly "regular" or roman as distinct to italic, as well as condensed—have led to font families, collections of closely related typeface designs that can include hundreds of styles. A font family is typically a group of related fonts which vary only in weight, orientation, width, etc, but not design. For example, Times is a font family, whereas Times Roman, Times Italic and Times Bold are individual fonts making up the Times family. Font families typically include several fonts, though some, such as Helvetica, may consist of dozens of fonts. Helvetica, Century Schoolbook, and Courier are examples of three widely distributed typefaces.
DocFamily supports different font formats, such as True Type Fonts (PDF, PostScript), Adobe Type-1 Fonts (PDF, PostScript), Raster-Fonts (AFP only) and Outline Fonts (AFP only).
