“Author” refers to any designer, engineer, programmer, technical writer or other person who contributed to the Font Software. “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. “Original Version” refers to the collection of Font Software components as distributed by the Copyright Holder(s). “Reserved Font Name” refers to any names specified as such after the copyright statement(s). This may include source files, build scripts and documentation. “Font Software” refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives. The fonts and derivatives, however, cannot be released under any other type of license. 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 OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. 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. SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007 This license is copied below, and is also available with a FAQ at: The below example instructs user agents to place the "A" and "V" characters closer together than the standard distance between characters.This Font Software is licensed under the SIL Open Font License, Version 1.1. Each carries references to at least two characters (attributes u1 and u2) and an attribute k that determines how much the distance between those characters should be decreased. Two more elements can be defined inside font: and. Again, you can use arbitrary SVG to define the glyph, which allows for great effects in supporting user agents. If you also specify the lang attribute on a glyph, you can further restrict it to certain languages (represented by xml:lang on the target) exclusively. It defines the unicode code point represented by this glyph. The actual glyphs are then defined by elements. For simple glyphs, however, you can add a d attribute - this defines a shape for the glyph exactly like how standard SVG paths work. You can use literally any other SVG elements in here, even, or. It also shows how glyphs are created: By adding any graphical SVG content inside. This defines what should be displayed if a certain glyph is not found in the font and if there are no fallback mechanisms. The above example states that if the renderer has a local font available named "Super Sans Bold", it should use this instead.įollowing is a element. You can point to external sources for font declarations by means of its children and. Its child, the element, corresponds to CSS' src descriptor in declarations. All following attributes are rendering instructions for the font layout engine for example, how much of the glyphs' overall heights are ascenders. The font-weight and font-style attributes have the same purpose as the equivalent descriptors in CSS. In the example above, the first and most important to be defined is font-family, the value of which can then be referenced in CSS and SVG font-family properties. It defines basic properties of the final font such as weight, style, etc. The element is the SVG equivalent of the CSS declaration. There are several accompanying attributes that help further define the basic glyph-box layout. The value 1000 sets a reasonable value to work with. The horiz-adv-x attribute determines how wide a character is on average compared to the path definitions of the single glyphs. This bears an id attribute, to enable it to be referenced via a URI (see below). glyph-orientation-horizontal Deprecated.
