摘要： Methods and apparatus, including computer program apparatus and systems, for processing text that includes coded (character based) and noncoded (image based) representations of text. The invention includes deriving a correction factor from a coded representation of a second unit of text and an original noncoded representation of the second unit of text, and modifying a representation of a first unit of text in accordance with the correction factor, where a common font typeface is attributed to both the first and second units. The collection factor can be calculated by rendering a coded representation of the second unit of text in the font typeface to generate a rendered representation, calculating a reference ratio from the rendered representation and an optical density of an original noncoded representation of the second unit of text, and inverting the reference ratio to calculate the correction factor. Where the first unit of text includes a word, the optical density of the word can be adjusted by modifying a bitmap representation of the word, where pixels are added to, or removed from, the bitmap, or the bitmap is left unchanged, according to the value of the correction factor.

摘要： Method and apparatus rendering a two-dimensional resolution-dependent raster image as applied to a three-dimensional surface modeled object. The rendering may be performed by digital electronics, a programmed computer processor, or a combination of them. Rendering includes mapping the 2-D raster image to a portion of a 2-D parametric map of a 3-D object, rendering the 3-D object as a 2-D vector resolution-independent output, and mapping the mapped raster image from the 2-D parametric map to a 2-D output space. Embodiments may include one or more of the following features. The raster and vector output is mapped to a 2-D display space. A clipping path is established for the raster image and mapped to the 2-D parametric map and to the 2-D display space. The raster image is edited and masked while displayed on a display of the 2-D parametric map. The vector output and raster output are integrated to generate a final output including both vector and raster data. The final output is sent to a printing device and rasterized by the printing device.

摘要： A method and system for compositing graphical images, wherein an advanced adjustment layer may be applied during a compositing process to a set of image layers 1 ... n , or to any subordinate subset of such image layers. One or more adjustment layers are applied to an intermediate merged image, generated by compositing previous image layers, and the adjusted result is stored as a temporary image. The temporary image is then in turn composited with the intermediate merged image. Any remaining image layers are then composited in with the intermediate merged image to generate a final merged image. The invention allows a user to apply a vast array of effects without requiring significant new knowledge on the part of the user. For example, if there are "A" adjustments and "T" transfer modes, the present invention allows AxT effects which leverage existing knowledge of the user of only A+T functions.

摘要： A computer-implemented method traps an edge in a color page described by page data, independently of the output device. The method comprises identifying, based on page data for a color page, an edge and first and second adjacent regions having the edge as a common boundary. defining a clip region, including the edge and at least part of one of the first and the second regions, and generating and storing device-independent trap data representing the clip region for use by an unspecified output device for trapping the edge. A page trapped by the method for output on an unspecified output device includes trap data for at least one edge represented in the page, the trap data for each edge comprising edge data, defining the edge, adjacent region data, describing a first and a second adjacent region sharing the edge as a common boundary, and clip region data, defining a clip region including the edge and at least part of the first or the second adjacent regions.

摘要： A method and apparatus for tracking invalidation information in tiled pixel image representations that combines the concept of an invalidation rectangle with the concept of invalid tile flags. A pixel is considered as being possibly invalid if and only if it lies within the invalidation rectangle and the tile containing that pixel is flagged as invalid. In accordance with the present invention, to invalidate an area, the implementing program generates an invalidation rectangle so that it bounds the area and the previous invalidation rectangle (if not empty), and also sets the invalid tile flags in the tiles overlapping that area. To validate an area A within an image, the inventive method performs the following steps: Define area B as the intersection of the area A to be validated with the invalidation rectangle. If area B is empty, the process is done: no pixels in area A are invalid. If area B is not empty, then determine which tiles intersect area B. For each tile intersecting area B, if the tile is marked as valid, and more tiles need to be processed, get the next tile that intersects area B. If all tiles have been processed, the process is done. If a tile is marked invalid, then define area C as the intersection of the area covered by the tile with the invalidation rectangle. Then validate area C by recalculating all of the pixels in area C, and clear the invalid flag for that tile. If more tiles need to be processed, the next tile is fetched. Otherwise, the process is done: no pixels in any area C - and hence in area A - are invalid.
