摘要： Described is a method and system in which storyboard objects coordinate the animation of multiple elements and/or media displayed on a computer graphics display. Storyboards relate properties of elements in an element tree to a timeline, such that the properties associated with a storyboard are animated/play together as a group by starting, stopping, seeking or pausing the storyboard. Triggers, such as controlled by user interaction with the displayed information, including property triggers that change values in response to a state change, and event triggers that fire events, may cause the storyboard to start, stop, pause and seek. Storyboards may be used in XAML-based programs, and may be directly associated with elements, or indirectly associated with elements via styles. Complex properties and changeables are supported. Media playback may be controlled via storyboards, and thereby coordinated with other media playback and/or animations.

摘要： A visual tree structure as specified by a program is constructed and maintained by a visual system's user interface thread. As needed, the tree structure is traversed on the UI thread, with changes compiled into change queues. A secondary rendering thread that handles animation and graphical composition takes the content from the change queues, to construct and maintain a condensed visual tree. Static visual subtrees are collapsed, leaving a condensed tree with only animated attributes such as transforms as parent nodes, such that animation data is managed on the secondary thread, with references into the visual tree. When run, the rendering thread processes the change queues, applies changes to the condensed trees, and updates the structure of the animation list as necessary by resampling animated values at their new times. Content in the condensed visual tree is then rendered and composed. Animation and a composition communication protocol are also provided.

摘要： The present invention is directed to a system and method for a unified composition engine that, in general, combines previously separate composition services. The unified composition engine provides a composition service used both in-process in conjunction with application programming interfaces (API's) and on the desktop as the desktop compositor.

摘要： Described is a method and system in which timing intervals are generated from clock properties, and used to interpolate values for smooth animation. A high-level component maintains a set of clocks related to animated objects and/or linear media in a scene graphs. The clocks correspond to clock properties received from an application program. The clocks are processed into event lists at the higher level, from which timing interval data is generated and passed to a low-level component. The low-level component, which generally operates at a faster rate than the high-level component, uses the timing interval data to rapidly calculate current values for an animated object. Interaction, such as to pause an animation or resume a paused animation, causes the high-level component to re-compute the event list and regenerate new animation intervals for affected clocks. The new animation intervals are passed and used by the lower-level component.

摘要： In aspects, a class hierarchy is defined that provides definitions of methods for operating on at least bitmaps and vector graphics. A software developer may instantiate an object according to a class definition of the class hierarchy and assign it to any variable (e.g., a control's property) having a type of an ancestor class of the class. The object may be associated with an image internally represented as bitmap, vector graphics, or some other representation. The control does not need to be aware of how the image is represented. Rather, to draw an image associated with the object, a draw method associated with the object may be called.

摘要： Described is an adaptive scheduler associated with a desktop window manager that dynamically controls the rate at which graphics frames are composed. Values corresponding to performance when composing a frame are measured, and the frame composition rate is adjusted as necessary based on the values. The measured data is sampled to provide smooth adjustments. The sampled data is evaluated as to whether the current frame rate is too slow, too fast, or acceptable. If too slow, the frame rate may increased relative to the refresh rate, while if too fast, the frame rate is decreased relative to the refresh rate. In one implementation, the frame rate is too fast if a count of missed frames achieves a missed threshold value, or if a count of late frames achieves a late threshold value. The frame rate is too slow if a count of early frames exceeds an early threshold value.
摘要翻译：描述了与桌面窗口管理器相关联的自适应调度器，其动态地控制组合图形帧的速率。测量与构成帧时的性能对应的值，根据该值根据需要调整帧合成率。测量的数据被采样以提供平滑的调整。评估采样数据是否当前帧速率太慢，太快或可接受。如果太慢，帧速率可能相对于刷新率增加，而如果太快，则帧速率相对于刷新率降低。在一个实现中，如果错过的帧的计数达到错过的阈值，或者如果后期帧的计数达到迟到的阈值，则帧速率太快。如果早期帧的计数超过早期阈值，则帧速率太慢。
