20100164983 | LEVERAGING GRAPHICS PROCESSORS TO OPTIMIZE RENDERING 2-D OBJECTS - 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. | 07-01-2010 |
20110310427 | PRINTING DIRECT2D-RENDERED ITEMS - Technology described herein is directed to converting display-rendering instructions (e.g., DIRECT2D) into print-rendering instructions (e.g., EMF, WMF, XPS, and SVG). For example, a request to print an item (e.g., document) is received, the item being displayable on an output device when display-rendering instructions are executed. A print render target is created that includes an instructions converter. The display-rendering instructions are routed to the print render target. The instructions converter maps the display-rendering instructions to the print-rendering instructions, which are usable to print the item. | 12-22-2011 |
20110310439 | OPTIMIZED FONT SUBSETTING FOR A PRINT PATH - Subject matter described herein is directed to providing font-rendering information (e.g., XPS file) that is usable to print a document. For example, a font file is received that defines a font type included in the document. A determination is made that a quantity of pages of the document does not exceed a subsetting-optimization threshold. When the quantity of pages does not exceed the threshold, a subsetted font file of the font type is generated. The subsetted file is provided, such as via the spool file, to a print subsystem. | 12-22-2011 |
20130063475 | SYSTEM AND METHOD FOR TEXT RENDERING - A method for text rendering that is well suited for use in a computing device with a high resolution display but a low-power graphics processing unit (GPU). The method may comprise calculating a coverage representation of the text in a format that can be efficiently processed by the GPU. As a result, the GPU may perform anti-aliasing and subsequent operations in the rendering process. Efficient processing may be achieved by providing the coverage representation in a format that allows values associated with pixels to be computed based on a byte-aligned chunk of bits in the coverage representation. Additionally, processing on the chunks may be performed using at least one lookup table. For large filtering kernels used for anti-aliasing, the lookup tables may be partitioned into portions dependent on dynamic text characteristics and those independent of the dynamic text characteristics. | 03-14-2013 |
20130088505 | CACHING COVERAGE VALUES FOR RENDERING TEXT USING ANTI-ALIASING TECHNIQUES - Techniques for calculating sub-pixel coverage values for text to be displayed, so as to enable caching of the sub-pixel coverage values. The sub-pixel coverage values may enable a linear combination of color information for the text with color information for one or more other, overlapping display elements for calculating composite color values to be used in controlling a display. Such composite color values to be used in controlling sub-pixels of a display may be calculated, in some embodiments, without performing a gamma correction process. Also described are techniques for retrieving cached sub-pixel coverage values and combining the values with color information for text and for other, overlapping display elements to calculate composite color values for sub-pixels of a display. At least one graphics processing unit (GPU) may be configured to perform operations using the sub-pixel coverage information and to calculate the composite color values for the sub-pixels. | 04-11-2013 |
