Abstract: A method for rendering a page, including: obtaining an electronic document (ED) identifying a main object and multiple shadow parameters; determining a main bounding box surrounding the main object on the page; creating a main brush including the main object; calculating a shadow bounding box based on the main bounding box and at least one of the multiple shadow parameters; creating a shadow brush by applying a shadow transformation matrix to the main brush, where the shadow transformation matrix maps the main object to a shadow defined by the multiple shadow parameters; inserting, into a main display list for the page, a set of instructions to: paint the shadow bounding box with the shadow brush; and paint the main bounding box with the main brush.

Abstract: Methods for utilizing existing typesetting applications to render documents specified in a markup language that may include objects not supported by the typesetting application are presented. In some embodiments, the method comprises parsing the document to identify objects not natively supported by the typesetting application and extract information including bounding box information pertaining to the identified objects. The typesetting application may be invoked and provided with bounding box information for the identified objects and with instructions to disregard the identified objects. The output of the typesetting application is parsed to determine layout information that corresponds to the identified objects and the identified objects may be processed using the corresponding layout information. In some embodiments, the methods disclosed may permit the use of the TeX typesetting application with documents specified in OOXML.

Abstract: Systems and methods for managing data in complex containers permit atomic addition of a plurality of data items to the containers. Each data item can occupy contiguous memory locations, although the plurality of data items may be mutually discontiguous. The method comprises creating a package object, which comprises an externally accessible array of pointer and associated integers. Each pointer points to the start of a memory location holding a distinct data item and the associated integer represents the size of the data item referenced by the pointer. A function associated with an external interface of the container determines a quantity of memory to hold the plurality of data items and invokes an externally accessible write function in the package object to add the plurality of individual data items to the container at specified locations if there is adequate memory available to hold the plurality of data items.
