Abstract: Current techniques for rendering content using data on multiple devices are generally ineffective and/or inefficient. This disclosure provides more effective and/or efficient techniques for rendering such content. The techniques optionally complement or replace other methods for rendering content.

Abstract: This disclosure is directed toward systems and methods of pre-multiplied alpha handling during image processing operations. The image processing circuitry may include hardware that enables removal and insertion of pre-multiplied alpha content into red, green, blue (RGB) pixel values during gamma and scaling operations. The division by alpha and multiplication by alpha hardware may enable removal of pre-multiplied alpha content to RGB pixel values prior to gamma operations and insertion of pre-multiplied alpha content into RGB pixel values prior to scaling operations.

Abstract: A system with a display generation component displays a user interface object overlaying a portion of video content. When display properties of the portion of the video content meets first criteria, the system displays a first variant of the user interface object, overlaying the portion of the video content, having an appearance that is based on the portion of the video content. The first variant is generated with a first range of values for a first display property of at least the portion of the video content. When the display properties of the portion of the video content meets second criteria, the system displays a second variant of the user interface object, overlaying the portion of the video content, having an appearance that is based on the portion of the video content. The second variant is generated with a third range of values for the first display property.

Abstract: An electronic device, while displaying the user interface of an application in a first mode, displays an affordance with a first appearance over a portion of the user interface, and values of display properties of the affordance change in accordance with a change in values of display properties of the portion of the user interface that underlies the affordance, in accordance with a first set of rules. Upon transitioning from displaying the user interface in the first mode to displaying the user interface in a second mode, the affordance is displayed with a second appearance, and values of display properties of the affordance change in accordance with a change in the values of display properties of the portion of the user interface that underlies the affordance, in accordance with a second set of rules that are different from the first set of rules.

Abstract: A text messaging system that allows messaging apps to send one or more layer identifiers that can specify content for a layer and Z depth of that layer relative to other layers in a text message transcript such as a sent message layer and a received message layer.

Abstract: An electronic device may include a display panel and processing circuitry. The display panel may display frames of image data having a static border that remains the same across multiple frames and a dynamic border that changes between a first frame and a second frame. The processing circuitry may apply a static gain value set from a static gain map to pixels to reduce or eliminate aliasing image artifacts along the static border. The processing circuitry may also apply a changing gain value set from a dynamic gain map to pixels to reduce or eliminate aliasing image artifacts along the dynamic border.

Abstract: The subject disclosure provides systems and methods for providing privacy-preserving social attribution for electronic devices. For example, when information is received from a contact of a user at the user's electronic device, various applications at the electronic device may later display the received information. It can be desirable to attribute the displayed information received from the contact to that contact, without exposing identifying information of the contact to the displaying application. Aspects of the subject technology include a system process that generates an image including contact information, that can be rendered in a user interface of an application, without providing the image or the contact information to the application.

Abstract: Systems, methods, and computer readable media for selectively placing an application into a reduced-priority rendering mode during system user interface (UI) operations are described. Techniques disclosed herein transition an executing (foreground) application from a synchronous render mode (having a first render priority) to an asynchronous render mode (having a second, lower, render priority) when the system moves from supporting execution of the application into displaying a system UI. In this new state, the application's UI display element (e.g., an icon or reduced size viewing window) may continue to be updated (e.g., in accordance with the lower render priority) but does not interfere with the system UI's responsiveness.

Abstract: A value of a display property of an affordance changes based a value of the same display property of a portion of content over which the affordance is displayed. The value of the display property of the affordance is constrained to vary within a second value range smaller than a first value range over which the value of the display property of the content is permitted to vary. If the change in appearance of the content meets range-switching criteria, the value of the display property of the affordance is changed within a third value range. The third value range is different from the second value range and is smaller than the first value range. If the change in appearance of the content does not meet the range-switching criteria, the value of the display property of the affordance is changed within the second value range.

Abstract: One disclosed embodiment is directed to graphics processing method for displaying a user interface. The method includes executing a plurality of graphic processing operation in a single rendering pass. The rendering pass includes several render targets. At least one of the render targets is designated as a memory-less render target. The memory-less render target is used to store intermediate data. The intermediate data is combined with the outcome of at least one other graphics processing operation to generate a combined result. The combined result is stored in the frame buffer memory for display.

Abstract: A value of a display property of an affordance changes based a value of the same display property of the portion of content over which the affordance is displayed. The value of the display property of the affordance is constrained to vary within a second value range smaller than a first value range over which the value of the display property of the content is permitted to vary. A decrease of the value of the display property of the content causes an increase of the value of the display property of the affordance based on the magnitude of the value change for the content and the second value range. An increase of the value of the display property of the content causes a decreases of the value of the display property of the affordance based on a magnitude of the value change for the content and the second value range.
