摘要： Embodiments enable a graphics processor to more efficiently process graphics and compositing processing commands. In certain embodiments, a client application submits client graphics commands to a graphics driver. The client in certain embodiments can notify a window server that client graphics commands have been submitted. In response, the window server can generate compositing processing commands and provide these commands to the graphics driver. Advantageously, a graphics processor can execute the client graphics commands while the window server generates compositing processing commands. As a result, processing resource can be used more efficiently.

摘要： Techniques to generate partial display updates in a buffered window system in which arbitrary visual effects are permitted to any one or more windows (e.g., application-specific window buffers) are described. Once a display output region is identified for updating, the buffered window system is interrogated to determine which regions within each window, if any, may effect the identified output region. Such determination considers the consequences any filters associated with a window impose on the region needed to make the output update.

摘要： A method of constructing a repair path around a non-available component in a data communications network is described. The data communications network has, as components, nodes and links therebetween defining a network topology. The non-available component is a member of a shared risk group of components commonly renderable non-available. The method comprises the step, performed at a repairing node, of identifying as a repair target a neighbour component of the non-available component. The method further comprises the step of constructing a repair network topology omitting the shared risk group. The method further comprises the step of constructing a repair path to the repair target in the repair topology.

摘要： A window manager process hosts proxy window objects created by an application in a window manager display structure. A process in a device creates a local proxy view object within a window manager display structure for the window manager process. The process registers an identifier for a remote proxy window object which corresponds to an application display structure. The application controls processing of data used by the application. The process assigns the identifier for the remote proxy window object to the local proxy view object in the window manager display structure to create a composite display structure and renders the composite display structure to display an image on a display device. The image corresponds to the objects of the application display structure represented by the remote proxy window object. The window manager process controls rendering of the composite display structure.

摘要： This invention is directed to a system for processing media in an electronic device. An application operative to request the display of one or more graphics elements may be implemented on the electronic device. The application may identify graphics elements for display and organize the graphics elements in a layer tree for processing and display by a render server (e.g., a core animation render server). To coordinate the processing of graphics elements of the application or of several applications, the electronic device may include a media server operative to receive media from the application and generate an image queue that includes video frames of the media. The render server may associate a slot ID with each image queue, while the media server may provide the slot ID to the application for inclusion in the layer tree. When the render server reaches a slot ID in the layer tree, the render server may identify and display the associated image queue.

摘要： The application programming interface operates in an environment with user interface software interacting with multiple software applications or processes in order to synchronize animations associated with multiple views or windows of a display of a device. The method for synchronizing the animations includes setting attributes of views independently with each view being associated with a process. The method further includes transferring a synchronization call to synchronize animations for the multiple views of the display. In one embodiment the synchronization call includes the identification and the number of processes that are requesting animation. The method further includes transferring a synchronization confirmation message when a synchronization flag is enabled. The method further includes updating the attributes of the views from a first state to a second state independently. The method further includes transferring a start animation call to draw the requested animations when both processes have updated attributes.
