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.
摘要翻译：本发明通常涉及一种用于选择使用标记语言文档将多个预先存在的字体分组到单个字体系或“虚拟字体”中的字体的方法。标记语言文档包括关于使用家庭内单个字体的条件的规则。这允许例如字体开发者以有效的方式创建使用若干预先存在的字体的国际字体。

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.
摘要翻译：描述了一种系统和方法，通过该系统和方法，可以以作者选择的粒度级别在计算机显示器上呈现的文本元素（例如，包括字符或字形的文本的段落，行或任何子集）可以单独地或集体地动画化。文本的动画可以通过直接编码（例如，标记）来设置动画属性，或者通过在渲染之前通过指定在文本相关数据上执行的动画代码来指定。动画的文本可能是静态的，或者在运行时从外部源动态获取。动画文本作为一个整体与文本对象中相同元素的其他文本保持一致，直到生成单独的字形的处理级别运行，并且与每个字形运行相关联的动画变换将被动画化。还描述了一种支持文本动画的API。

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.
摘要翻译：一种用于文本呈现的方法，其非常适合于具有高分辨率显示器但是低功耗图形处理单元（GPU）的计算设备。该方法可以包括以可由GPU有效处理的格式来计算文本的覆盖表示。结果，GPU可以在渲染过程中执行抗锯齿和后续操作。可以通过以覆盖表示中基于字节对齐的位的块来计算允许与像素相关联的值的格式来提供覆盖表示来实现高效处理。另外，可以使用至少一个查找表来执行块上的处理。对于用于抗锯齿的大型过滤内核，查找表可以分为依赖于动态文本特征的部分，也可以分为独立于动态文本特征的部分。

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： 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.
