    Abstract: The present invention displays text within a region by identifying text boxes within the region. To identify the text boxes, the invention uses scan lines that are spaced at intervals that are smaller than the text height of the text to be placed in the boxes. These scan lines are combined to identify the full text boxes. Additionally, under the invention, a region is transformed before text boxes are generated for the region. The transform is an inverse of a text transform that is applied to the text placed in the region. This allows rotated and skewed text to be placed in the region. The invention also facilitates displaying a single text string across several disjointed regions.

    Abstract: A system and method for editing images. Each image editing operation is described by a few parameters. Multiple users can share image processing changes by sharing a few set of parameters instead of the whole bitmaps of the images. An Editing List describes the parameters defining the image changes. The size of Editing List is very small and is ideal for network transmission and collaboration. Image Editing Lists are independent of the images themselves. By decoupling the Image Editing Lists from the original bitmap images, other advantages are obtained. For instance, the same Editing List can be applied to other images and also to multiple images at the same time. Rendering of the modified images can be performed at a later time and only when necessary. In case of collaborative editing, the transmission time is reduced drastically.

    Abstract: An image storage and processing method constructs, clips, fills, and combines arbitrary 2-dimensional shapes in an advanced graphics system. The method supports processing of anti-aliased images by compressing the image into a novel AlphaRegion data structure. AlphaRegion encodes into the data structure both the partially transparent as well as the fully opaque alpha values of an image according to rectangular bands. A band is a contiguous series of scan lines that have the same pattern of alpha values in a single direction. AlphaRegion encoding results in a more compact representation than possible in a conventional bitmap, but without losing the anti-aliasing features. AlphaRegion can be constructed either by supersampling sub-scan lines of an image, from the scan lines of a gray-scale image, from an existing conventional 1-bit Region or alpha mask buffer, or directly from a scan-line conversion of a geometric shape. AlphaRegion stores image data into three arrays, yInfo, xInfo and alphaData. Methods provided with AlphaRegion include rendering methods for filling or clipping the area on the drawing surface and methods for combining two AlphaRegions using boolean combination operators OR, AND, XOR, SUBTRACT, or SUBTRACT_FROM.

    Abstract: The present invention provides a method, apparatus and computer-readable medium for providing high quality substantially visually error-free conversion of color images. The method maps the color values to an expanded colorspace to represent substantially all colors without perceptible visual error and labels an image determined by the mapped color values as an expanded colorspace image. Thus, the present invention may be utilized to provide a linear color management system. In a 16 bit color data value system, transparency/opaqueness information may be stored, and premultiplied or premultiplied and normalized values may be used for blending.

    Abstract: The present invention provides a method and apparatus for rendering images on a computer screen. Under the invention, a portion of a base image is described using a path. The path is then transformed using a non-affine transform to produce a transformed path. The transformed path is then rendered onto the computer screen. Another aspect of the present invention is a method and apparatus for rendering curves of any order and any dimension. In particular, the present invention provides a means for converting a function of any order and any dimension that describes one segment of a curve into a function that describes a different sized segment or an adjoining segment.

    Abstract: A system and method is described for manipulating text relative to a curved reference line in order to transform a character, rendered in a particular font, to generate a warped character with the degree of warping reflecting the local curvature of the curved reference line. The curvature of the reference line is reflected in the nature of quadilaterals, i.e., quads, generated for a corresponding rectangle on a straight reference line. The coordinates of the corners of the quad provide the parameters to carry out the transformation. Such rendering improves the appearance of the text and provides a method that modifies available fonts in a flexible fashion without the need to generate new fonts.
