摘要： A quality level determining the extent to which each image file is compressed is automatically computed for each image file in a set to ensure that the total size of the compressed image files does not exceed a predefined limit. The compressed size of each image file is initially determined when compressed at a predefined minimum acceptable level and at a nominal level. The relative complexity of the image files is determined based upon their high frequency energy content. As a function of the image file complexity, and starting with the compressed sizes initially determined, the appropriate quality level is determined for compressing each of the image files in an iterative process that ensures the total size of the compressed image files does not exceed the predefined limit, while retaining acceptable quality. Thus, a set of image files can be compressed optimally to fit within a limited storage.

摘要： A single instruction stream multiple data steam data flow signal processor and method for implementing macro data flow control, in which a plurality of data processors have contentionless access to global memory data. Data processing tasks for the data processors, such as primitive executions together with graph scheduling processes, are developed asynchronously and in parallel from a command program and a macro data flow control graph.

摘要： An original media object, such as an image, is edited without loss of the data comprising the media object. Changes applied to the media object are defined by metadata associated with the media object. For example, metadata define the cropping of an original JPEG image without loss of the original image. The metadata from a previous editing session can be used to further revising a change to the media object. Preferably, the metadata are stored as a stream in a substorage of an object linking and embedding (OLE) file. For display purposes, and for ease of modification, an edited version of the media object is stored as another stream of data in the substorage of the OLE file. The edited version of the media object is preferably compressed and serves as an intermediate object for faster display during editing and as a surrogate if the original media object is unavailable.

摘要： Application content and system content are composited to create composited frames for display by drawing foreground application content into an application buffer, building a reconstruction buffer, drawing system user interface content on top of the foreground application content in the application buffer, and displaying a composited frame by sending the application buffer directly to display hardware for display. The reconstruction buffer contains portions of the foreground application content copied from the application buffer. When system user interface content is being updated, the reconstruction buffer is used to recreate the original foreground application content. Updated system user interface content and original foreground application content are then used to create additional composited frames for display.
