Embodiment Construction

[0020] As noted above, aspects of the present disclosure relate to systems, apparatus, methods, and computer-readable media for obtaining and processing fonts in an online web environment. A font as used herein may refer to a collection of characters in a typeface. In one or more examples, a font may refer to the set of all characters defined for that particular typeface. A user may upload font files to a web server in a font file format that may only be compatible with one or more specific types of applications, such as web browsers. Therefore, the web server can generate the second font file in another font file format compatible with other types of application programs and web browsers. Alternatively, users can upload font files in multiple font file formats rather than asking the web server to generate font files in other formats. Using a web server, the browser can obtain font files in the appropriate format. This allows users to use a variety of styles and fonts in th...

Abstract

The present invention provides reduced glyph font files. Documents that are created using a particular font often do not include all glyphs defined for the font. Accordingly, to reduce the amount of bandwidth needed to obtain the font used to create the document over a network, a font file may be created that includes a reduced set of glyphs. In one or more examples, the font file might only include the glyphs used in the document being viewed. Reduced glyph font files may be generated on-the-fly and / or cached for quick retrieval at a later time.

Description

technical field [0001] Aspects of the present disclosure relate to the creation and distribution of reduced glyph font files. Background technique [0002] Web documents such as web pages can use a variety of fonts to convey style and enhance aesthetics. In many instances, a web browser or user agent utilized to view a web document may not be equipped to view the document because the corresponding fonts are not loaded on the system. Therefore, the user agent, or the device on which the user agent operates, may need to obtain fonts over the network. Some font files can be large and therefore require significant transfer bandwidth. Font files generally include definition information for all glyphs, whether or not the glyphs are used by web documents. This represents a waste of bandwidth, since data is also transmitted to the user agent device when it is not needed. Contents of the invention [0003] A simplified summary is presented below to provide a basic understanding...
