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： 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.

摘要： A reader for displaying an electronic document provided in a predetermined format and allowing articles of the document to be read in the direction of their content information flow. The reader includes a selector to select an article of the document to be read. A displayer displays a first portion of the article in a manner which promotes comfortable viewing, and a navigator permits the display of the next and remaining sequential portions of the article in content flow (or reverse content flow) order. Preferably, the displayer pans and zooms, as necessary, to position the article portion in an article viewing window. A method for viewing electronic documents on a digital computer includes the steps of storing in the memory of the digital computer an electronic document, selecting an article to be displayed on an output device of the digital computer in an article view, displaying at least a portion of the article in the article viewing mode on the output device, and using an input device of the digital computer to cause a display of additional portions of the article to be displayed on the output device in the article viewing mode. These additional portions of the article are determined, at least in part, by predefined article sections and section links of the document so that the thread of the article can be followed in forward and reverse directions.

摘要翻译：本发明提供了一种用于选择每种原色的强度水平的方法，用于显示或打印由每种原色的指定百分比组成的预定的期望颜色。每种原色都具有从最小到最大值的预定数量的离散强度级别，并且将被显示在具有预定数量的单元格的矩阵上。该方法的第一步是确定每个原色的期望强度水平，并选择要在该强度水平显示该颜色的矩阵的单元数。然后将每种原色的这些单元以预定的顺序排列在矩阵中以显示所需的颜色。顺序的顺序是预先确定的，对于每种基色都是相同的。原色之一的序列的起始点是固定的，但是每个连续原色的起始点取决于前面颜色的单元格序列的结束单元格位置。使用本发明，由于存储颜色选择信息所需的存储单元的数量仅需要等于每个原色的可用强度级数的乘积，因此减少了所需的色彩存储量。
