Abstract: Methods and computer-readable media for displaying two-dimensional objects on a display device are disclosed. Rendering requests are received from an application to render two-dimensionally modeled graphics to a display device. Primitive geometries of drawing calls of the rendering requests are tessellated into sequences of triangles. The vertices of the triangles are mapped to a vertex buffer along with an index to identify associated constant data. Batching operations store and communicate calls and mapped data to a graphics processing unit by way of a three-dimensional rendering application program interface. Constant data associated with the mapped data are indexed and appended together in a constant buffer, thereby allowing drawing calls to be coalesced. A staging buffer and a staging texture are provided for batching text anti-aliasing operations. Shader fragments are precompiled and organized by way of a predetermined lookup table.

Abstract: An improved system and method for an extensible metadata architecture for digital images is provided. Executable software code may be operably coupled to a metadata query reader and a metadata query writer for requesting operations for manipulating metadata in an image file. The metadata query reader may be operably coupled to a decoder having a block reader for identifying metadata blocks in an image file and associating a metadata reader with each metadata block. Each metadata reader may then enumerate the metadata in the metadata block associated with that metadata reader. The metadata query writer may be operably coupled to an encoder having a block writer for associating a metadata writer with each metadata block to be written to an image file. Each metadata writer may then write metadata in the metadata block associated with that metadata writer.

Abstract: An improved system and method for an extensible codec architecture for digital images is provided. Executable software code may be operably coupled to a codec manager for requesting imaging operations to be performed on a digital image. The codec manager may receive the request to perform an imaging operation on the digital image and may select an imaging component, such as a codec, from one or more imaging components registered in the computer system for performing an imaging operation on the digital image. An arbitration manager may include functionality for requesting enumeration of the operations an imaging component may perform on a particular digital image. One or more pixel format converters may then convert the pixel format in the digital image to a pixel format supported by an imaging component installed on the system.
