摘要： Disclosed are methods, apparatus (1) and computer readable media for rendering at least one graphic object (80, 90) described by at least one edge (82-86, 92-98) into a raster pixel image (78) having a plurality of scan lines and a plurality of pixel locations on each scan line. For each scan line, coordinates of intersection of those edges of the objects that intersect the scan line are determined in a predetermined order. This is preferably achieved by processing edge records (418) using a number of buffers (402, 404,406, 412,420, 422) thereby enabling efficient sorting of edge intersections into order. For each adjacent pair of edge intersections, information (530) associated with the corresponding object is examined to determining a set of active objects (508, 510) for a span of pixel locations between the corresponding pair of edge intersections. For each span of pixel locations, the corresponding set of active objects is used to determine (600) a value for each of the locations within the span. The information may include one or more of a fill count, a clip count and other factors. A compositing model accommodating opacity is also disclosed, as are stack operations used to facilitate rendering and other features which contribute to fast processing of image components.

摘要： A method and apparatus for displaying color for selection is disclosed. The method includes the steps of displaying a currently selected color in a first predefined area and displaying a series of blend areas each containing a blend from a first blend color to a second blend color, and at least one of the blend colors being substantially the same as the currently selected color. Preferably, each of the second colors is a predetermined distance in a color space from the currently selected color. The first predefined area may be located in a central area and each of the blend areas may be located around the central area and the at least one of the blend color in the blend area being located substantially closest to the central area. The blend areas are located radially around the central area. The color space is preferably the CIE L*a*b* color space and the blends are substantially continuous in the CIE L*a*b* color space. In an alternate embodiment, there is disclosed a method and apparatus for generating colors for selection of a color by a user. The method comprises the steps of (a) selecting a first color, (b) generating a plurality of color blends, each having the selected first color at one end of the corresponding blend and a second color at an opposite end of the blend wherein the second colors are related to the first color and each other by predetermined characteristics, and (c) displaying the selected first color and the plurality of blends. The blends are radially configured around the selected first color dependent on one of the characteristics with each blend having the corresponding selected first color at the one end positioned adjacent to the selected first color. The plurality of second colors is generated dependent upon one of the predetermined characteristics being a radial distance from the selected first color in a color space. A further step involves, once interation of steps (a), (b) and (c) has been completed, mapping a palette image using the plurality of blends corresponding to the resultant selected first color.

摘要： A method determines a color at a plurality of locations in a region of overlap of a first graphic element and a second graphic element, with each graphic element having a color value and a partial opacity value defined at each location. The method includes the steps of determining a transfer color as a combination of the color value of the first graphic element and the color value of the second graphic element, with the transfer color being independent of the opacity values of each element, and determining a first color value of a set of possible color values. At least one color value in the set of possible color values is derived from the transfer color, and another color value in the set of possible color values is derived from the color value of at least one of the first graphical element and the second graphical element. Additional steps include selecting the first color value from the set of possible color values to determine the color at a first selected location in the region of overlap, and determining a second color value from the set of possible color values, and selecting the second color value for a second selected location in the region of overlap. The selection of the first and second color values is at least dependent upon the partial opacity value of the first or second graphical elements.

摘要： An anti-tampering method for processing documents is disclosed. The method comprises, in regard to an encoding step, the steps of resolving (in a step 2303) in regard to an N-level image to be recorded, a pixel of the image into a major component having N possible values, selecting (in the step 2303) a pattern element depending upon the major component and the position of the pixel in the image, and recording the selected pattern element (in a step 2308) onto a transfer medium. In regard to a corresponding decoding step the method comprises extracting (in a step 2405) from the recorded document, a retrieved pattern element for said pixel, determining a pattern element (in a step 2407) depending upon a major component extracted from the retrieved pattern element and the position of the pixel on the recorded document, and comparing (in a step 2409) the retrieved pattern element and the said determined pattern element.

摘要： A system, method and language for compositing or creating images is disclosed. The images typically comprise a plurality of graphical elements each including color and opacity information. The system utilizes operators having the graphical elements as operands in which the operators combine the operands according to a function defined by the operators, the color information, and the opacity information, to produce new graphical elements. One part of the system includes interpreting the language by parsing and executing a sequence of statements and forming an expression tree the nodes of which comprise the graphical elements. Instructions are then derived from the tree. Another part permits the compositing of opaque graphical elements and associated clipping operations. Bounding box method are used for locating active areas of graphical elements from the nodes. Manipulation of the expression tree is used to reduce the expected execution time of the compositing commands. An architecture is disclosed for implementing the system.

摘要： The present invention provides a method and apparatus for displaying a grouped structure (23) in a computer graphics image. This involves providing at least one selection tag (18) for the grouped structure. A group display mode is used so that, when a selection tar (18) of the grouped structure is selected, portions (25,26) of the structure of the group structured are determined. The portions (25,26) of the structure of the grouped structure (23) are then displayed. Preferably, the displayed portions (25,26) initially comprise a top level portion (25) of the grouped structure (23). This further involves displaying further levels (26) of the grouped structure (23). Preferably, the displayed portions of the structure are displayed in a tree format. Optionally, the tree format includes nodes (25,26) denoting part of the grouped structure (23). This involves providing means for selecting a current node (26) within the tree format and displaying at least the child nodes (27,28), if any, of the current node (26), upon selection of the current node (26). Optionally, a sub-portion of the displayed portions of the structure can be selected and interactive access can be provided to the selected sub-portion.

摘要： A method of creating a series of font characters (101) on a computer system (150) is disclosed. A series of font outlines (111) and source artwork (112); a series of manipulation tools (116) for the manipulation of aspects of the outlines and artwork. Such an arrangement provides for the creation of substantially arbitrarily complex font structures from the outlines, artwork and manipulation tools. A series of font characters is then formed through the application of the complex font structures to each of a base font outline in the series of font characters. Preferably, the complex font structures can comprise a graphical expression tree of operations (120) to be performed in the creation of a font and the tree includes an outline of a font character. The manipulation tools can include tools for distorting, replacing or compositing the outline of a font and can further include the tools for the application of morphological and non-morphological effects to the font outlines. A data structure for such font creation is also disclosed which includes records (90-97) of attributes of glyphs used to form the outlines including their shape, color, opacity and where appropriate compositing or blending with graphic object or pixel-based images.
