  • Method and system for registering binary data
    Patent number: 7603407
    Abstract: Systems, methods, and products provided for facilitating the reuse of data blocks. In one implementation, a registration server receives request data objects from programs that request use of a data block. When the data block is not already registered with the registration server, the registration server registers the data block, for example in a list of registration data objects. A registration handle object is returned to the requesting program and provides a reference to the resources for accessing the data block. The present invention facilitates efficient use of resources in connection with multiple requests for a data block because resources needed for handling the binary data block are not duplicated.

  • Method and structure for generating output data of a digital image including a transparent object
    Patent number: 7236642
    Abstract: A method for generating output data for a transparent object in a digital image creates a plurality of image areas. The plurality of image areas covers a total area of the transparent object in the digital image. Each image area covers a different portion of the transparent object. The method combines information of the transparent object covered by an image area with information of a background image of the digital image also covered by the image area. The background image does not include the transparent object.
