摘要： The invention describes a method for reconstructing characters in a document, which are expressed in one or more fonts, to convert the characters to a different font designed to closely match characters from a plurality of fonts in an aesthetically pleasing manner. This is accomplished by first selecting a first character from the document and thereafter substituting for the first character the same character constructed from the different font and having the same width as the first character, the characters of varying widths within the different font being designed to have aesthetically pleasing relationships between their parts irrespective of width. The construction and substitution of characters of the different font for each of the characters in said document needing reconstruction is continued in the same manner until all the characters in the document needing reconstruction have been substituted, thereby creating a reconstructed document having an aesthetically pleasing relationship among the characters in the document. Thereafter the reconstructed document is stored, printed or displayed.

摘要： Method and apparatus for filtering non-text information from a page containing text, the text being associated with a color. The page is represented as an image in a first color space. The image is converted to a second color space that has a color channel closely associated with the text color. The color channel is selected and gray values are derived that correspond to text color channel values associated with cells in the image. Cells in the image having gray values of a predefined relationship with respect to predetermined threshold values are marked as text cells, and the remaining cells are identified as non-text cells. The gray values of the text and non-text cells are adjusted to increase the contrast between text and non-text information. The single-color space image may then be printed by a monochrome printer.

摘要： A graphical pattern placement technique automatically performed by a computer is disclosed. Initially, a path on an electronic document is provided and a graphical pattern is selected. Then, the graphical pattern is automatically placed along the path by a programmed computer such that the graphical pattern follows the orientation and curvature of the path.

摘要： The invention provides a method for selecting the intensity level of each of the primary colors for displaying or printing a predetermined, desired color to be composed of a specified percent of each of the primary colors. Each primary color has available a predetermined number of discrete intensity levels ranging from minimum to maximum and is to be displayed on a matrix having a predetermined number of cells. The first step in the method is to determine a desired intensity level for each primary color and to select the number of cells of the matrix which are to display that color at that intensity level. These cells of each primary color are then arranged in the matrix in a predetermined ordering to display the desired color. The sequence of the ordering is predetermined and the same for each primary color. The starting point of the sequence for one of the primary colors is fixed, but the starting point for each successive primary color is dependent upon the ending cell location of the sequence of cells for the preceeding color. Using the invention, the amount of color memory required is reduced because the number of storage cells required for storage of color selection information need only be equal to the product of the numbers of available intensity levels for each primary color.
