International Classification:

G06T011/00

US Classification:

358462000

Abstract:

Systems and methods of identifying and processing complex text are provided. If a presentation data stream contains a complex text string, a preselected control in the presentation data stream is inserted before the complex text string. A first parameter has a value indicating a control type for controlling processing of complex text, and a second parameter takes one or more values for enabling and disabling the processing of complex text. In processing complex text, responsive to a first predetermined type of control in a presentation data stream, if the first type of complex text processing is enabled, this processing is applied to a complex text string succeeding the first predetermined type of control in the presentation data stream. The first predetermined type of control includes a first parameter represented by a corresponding value for controlling the first type of complex text processing.

US Classification:

345467000, 358001110

Abstract:

Methods and systems for rendering code points on a presentation device with layout processing performed outside the presentation device. In one aspect, a layout processor translates one or more code points into a sequence of one or more glyph indices and corresponding positioning information. The glyph indices and corresponding positioning information may be included within a PTOCA control sequence. The glyph indices may be used by the presentation device to directly locate a corresponding glyph image in a font. The positioning information defines positioning of each glyph image so identified. Features and aspects hereof allow efficient layout of complex text in which glyph images and positioning may be dynamically determined in accordance with context or other attributes. The processing burden of such layout processing is removed from the presentation device without significantly increasing data transmission bandwidth between the presentation engine and external system utilizing the layout processor.

US Classification:

395150

Abstract:

A computer system for rendering text is provided. A keyboard is used to enter characters into the computer system. A character code corresponding to each entered character is generated. A particular font is chosen from a font table stored in memory. The font table contains a number of different fonts, with each font having a number of glyph indexes corresponding to a number of different glyphs. A character can have a plurality of different glyph indexes for a particular font. A processor maps the character code to a glyph index according to the selected font and later processes the glyph index. The glyph corresponding to the processed glyph index is then displayed.
