    摘要: Described is a system and method by which text elements to be rendered on a computer display (e.g., paragraph, line or any subset of text including a character or glyph) may be individually or collectively animated, at an author-selected level of granularity. Animation of text may be specified by setting animation properties via direct coding (e.g., in markup) or by specifying animation code to execute on text-related data, just prior to rendering. The text to animate may be static, or dynamically obtained at runtime from an external source. The text to animate is maintained as a whole with other text of the same element, in a text object, until a processing level that produces separate glyph runs, with an animation transform associated with each glyph run to be animated. Also described is an API that supports text animation.

    摘要: A method for developing a writing system analyzer. In one implementation, a writing system may be represented in syntax-directed translation. The syntax-directed translation representation of the writing system may be compiled to generate a writing system analyzer. In one implementation, the writing system may be represented in syntax-directed translation by creating an environment using header files with one or more declarations in source code form and formulating one or more rules for representing the writing system using the declarations.

    摘要: A method for displaying an input string of character codes as a sequence of glyphs. In one implementation, an ordered list of instructions for transforming an input string of character codes may be generated using syntax-directed translation. The ordered list of instructions may be executed to generate a sequence of glyph indices. A sequence of glyphs corresponding to the sequence of glyph indices may be displayed.

    摘要: The invention is generally directed to a method for selecting a font that uses a mark-up language document to group together multiple pre-existing fonts into a single font family or “virtual font.” The mark-up language document includes rules regarding the conditions under which individual fonts within the family are to be used. This permits, for example, a font developer to create, in an efficient manner, an international font using several preexisting fonts.

    摘要: A method for text rendering that is well suited for use in a computing device with a high resolution display but a low-power graphics processing unit (GPU). The method may comprise calculating a coverage representation of the text in a format that can be efficiently processed by the GPU. As a result, the GPU may perform anti-aliasing and subsequent operations in the rendering process. Efficient processing may be achieved by providing the coverage representation in a format that allows values associated with pixels to be computed based on a byte-aligned chunk of bits in the coverage representation. Additionally, processing on the chunks may be performed using at least one lookup table. For large filtering kernels used for anti-aliasing, the lookup tables may be partitioned into portions dependent on dynamic text characteristics and those independent of the dynamic text characteristics.

    摘要: Techniques for calculating sub-pixel coverage values for text to be displayed, so as to enable caching of the sub-pixel coverage values. The sub-pixel coverage values may enable a linear combination of color information for the text with color information for one or more other, overlapping display elements for calculating composite color values to be used in controlling a display. Such composite color values to be used in controlling sub-pixels of a display may be calculated, in some embodiments, without performing a gamma correction process. Also described are techniques for retrieving cached sub-pixel coverage values and combining the values with color information for text and for other, overlapping display elements to calculate composite color values for sub-pixels of a display. At least one graphics processing unit (GPU) may be configured to perform operations using the sub-pixel coverage information and to calculate the composite color values for the sub-pixels.
