Abstract: Systems, methods, and computer-readable media are disclosed for dynamic color adjustment of electronic content. In one embodiment, a system may determine a first background color corresponding to a color theme for use in presentation of electronic content, the color theme further specifying a first text color for displaying text. The system may convert the first text color to hue-saturation-value (HSV) color space, and modify a brightness component of the first text color to generate a second text color. The system may determine a first contrast ratio between the second text color and the first background color, and determine that the first contrast ratio satisfies a first threshold contrast ratio. The system may display the electronic content using the first background color, the electronic content including text having the second text color.

Abstract: Disclosed are techniques and systems to detect a layout of a source document. A process may include receiving content from a first page and a second page of the source document, designating sections in each page along a first direction of the page, and assigning similar sections to a group. For the group, the process may proceed by dividing sections for each page into discrete portions associated with 2D coordinate areas, and identifying sets of 2D coordinate areas for the discrete portions that contain content. The number of times each portion contains some content may be compared to a threshold to determine a layout of the group of sections.

Abstract: In some examples, a computing device may receive a content item for formatting, the content item including at least one scalable object to be rendered with a portion of content during presentation of the content item on an electronic device. The computing device may convert a complex shape element in the scalable object to at least one path command that includes a sequence of one or more paths that correspond to the complex shape element. The computing device may format the at least one path command for parsing by a content parser of the electronic device. Further, the computing device may associate the at least one path command with the portion of content so that the at least one path command will be rendered in place of rendering information for the scalable object that was originally included with the content item.

Abstract: Some implementations include identifying conflicts between multiple layers of supplementary content associated with a digital work (e.g., an electronic book). For individual conflicts between layers of supplementary content at one or more locations within the digital work, conflicts between layers may be resolved in favor of a higher priority layer. Upon resolution of the conflict, information associated with the higher priority layer for supplementing content at a particular location in the digital work may be determined. A visual identifier of the higher priority layer may be displayed along with content associated with the digital work at the particular location.

Abstract: A method and system to provide fonts for electronic publications is described. An example method includes receiving a request for an electronic publication from a user device, retrieving a font identifier of a font from the electronic publication, providing the electronic publication to the user device, determining, based on the font identifier, that at least one font file of the font is not stored on the user device, and providing the at least one font file of the font to the user device.
