Abstract: Systems, methods, and computer-readable media are disclosed for dynamic contrast adjustment for glyph rendering. Example methods may include rendering a first glyph associated with a font in a first font size, increasing a first contrast of the first glyph in the first font size by adjusting a first grayscale value associated with the first glyph in the first font size to generate an adjusted first grayscale value, and storing the adjusted first grayscale value in a grayscale mapping table associated with the font, the grayscale mapping table comprising a default grayscale value for the first glyph in a second font size. Example methods may include generating a font file comprising the first glyph and the grayscale mapping table.

Abstract: In some examples, additional content is provided with the main content of a content item presented on an electronic device. For instance, an occurrence of an event may call for presentation of an additional content portion concurrently with the main content of the content item. The additional content portion may interact with other additional content portions, the main content portion, and/or user inputs. In some cases, the additional content portion can be implemented by one or more plug-in modules having designated roles for providing respective different types of additional content. Accordingly, some examples provide a cross-platform module that receives events, selects one or more plug-ins in response to a received event, and causes the one or more plug-ins to perform a desired action for rendering and compositing additional content portions or features to be presented with the main content of a content item.

Abstract: Some examples include testing of software able to render a content item on a display of an electronic device. The testing may include capturing images of rendered portions of a content item and comparing the captured images with previously obtained reference images that have been verified to be correctly rendered. The testing techniques can be applied to conversion software that converts digital content items from one format to another and/or testing of the converted content items themselves. Additionally, content presentation software that displays digital content items on an electronic device, such as by interacting with rendering software, may also be tested using a similar technique.
Abstract translation: 一些例子包括测试能够在电子设备的显示器上呈现内容项的软件。 测试可以包括捕获内容项目的渲染部分的图像，并将捕获的图像与先前获得的被验证为正确渲染的参考图像进行比较。 测试技术可以应用于将数字内容项从一种格式转换到另一种格式的转换软件和/或转换的内容项本身的测试。 此外，还可以使用类似的技术来测试在电子设备上显示数字内容项目的内容呈现软件，例如通过与呈现软件交互。

Abstract: A processing device in a user device receives an electronic document comprising text in a first font of a plurality of fonts and a hint tag set comprising a suggested order of hint types for the first font, wherein a first hint type is arranged in the suggested order according to a corresponding quality score for the first hint type, the quality score indicating how closely characters from a simulated presentation of the text match a predefined presentation of the characters. The processing device determines a hint type for the first font from the suggested order of hint types and according to a capability of the user device and utilizes the hint type for a presentation of the text of the electronic document.

Abstract: A rendering optimizer captures content engagement feedback associated with a first interval during which electronic content is presented with a first set of rendering parameter values. The rendering optimizer adjusts at least one rendering parameter value of the first set of rendering parameter values by a step amount in a first direction to create a second set of rendering parameter values and captures content engagement feedback associated with a second interval during which the electronic content is presented with the second set of rendering parameter values. The rendering optimizer further adjusts the rendering parameter values to determine they result in an improvement in reading immersion.

Abstract: Some examples include segmenting text of a content item to include a plurality of segments or words. For instance, a module for segmenting a content item using a context-based segmenter into a plurality of segments, identifying segment boundary hints stored in the content item, and adjusting segments of the plurality of segments based on the identified segment boundary hints. Some additional examples include inserting segment boundary hints into a content item. For instance a module that segments the content item using a first segmenter and a second segmenter and inserting segment boundary hints into the content item where the results of the first and second segmenter differ.
