摘要： Methods, systems, and apparatus, including computer program products, for determining a complexity for a subregion of an electronic document page that includes one or more objects. In one aspect, a method includes dividing a subregion of an electronic document page into a plurality of cells, where the electronic document page includes one or more objects, the objects include one or more transparent objects, the subregion includes at least part of a transparent object, and each cell has an associated cell complexity. The method includes, for each object partly or completely located in the subregion, identifying cells that are overlapped by the object, and increasing the associated cell complexity for each of the identified cells. The method includes combining all cell complexities associated with all cells in the subregion to determine a complexity for the subregion.

摘要： The invention features a method, system, and computer program product. A source bitmap image, a destination bitmap image, a source image feature outline surrounding a source region of the source bitmap image, and a destination image feature outline surrounding a destination region of the destination bitmap image are received. A point-to-point correspondence between the source image feature outline and the destination image feature outline is generated, such that the point-to-point correspondence defines a reshaping of the source image feature outline. An interpolation surface is calculated interpolating an area of the source bitmap image that includes the source region. The interpolation surface is reshaped using the point-to-point correspondence.

摘要： Edges are detected in a raster image and generate parametric curves from the detected edges. The parametric curves are used to render a scaled version of the raster image. Some embodiments may allow edge locations within a raster image to retain a satisfactory level of sharpness when the raster image is scaled to a larger size.
