A method for displaying characters on a screen or printer, particularly kanji characters. The structure of the character is represented by stems and counters, both vertical and horizontal, the counters being the spaces between stems. The character is then adjusted to be displayed. Either the horizontal or vertical counters are grouped into a first chain of counters. The non-integral counter widths of this chain are adjusted in relation to the other counter widths within the chain, selected count...

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, t...

The method of displaying multitone images beginning with a grayscale original image capable of displaying a specific number of gray levels, which includes the steps of: (1) selecting a plurality of colors from the image, one for each of the multitones, each having a color value; (2) selecting a plurality of transfer functions, one for each of the selected colors; (3) converting each of the shades of gray, using the respective color values and the transfer functions, into a new color value; and (...

Method for displaying characters with improved legibility at relatively low resolution by modifying the center point fill method and displaying additional pixels as needed to maintain connectivity and avoid dropout problems. Additional pixels are turned on as needed where a black section of the character crosses the midline between two adjacent horizontal or vertical pixel centers. If the intersections of a black section of a character with a midline is entirely within one pixel which is not oth...

A user interface (UI) may be used in specifying spatial relationships between graphical elements in a graphics environment with drawing or graphical element manipulating functions. The UI interacts with the operating system through an application shell. A document engine, a graphics engine, and a constraint engine are coupled between the UI and operating system. A user may create a distribution frame with an area on a page of a document and a set of elements may be specified to be automatically ...

The present invention removes restrictions on the maximum data transfer rate provided by the Centronics.RTM. and PC-compatible parallel interface (i.e., standard parallel interface). Further, the present invention retains complete compatibility with the standard parallel port and peripheral device cable. With the present invention, a computer (i.e., host) is able to send data through a standard parallel port at a high rate by eliminating the Busy handshaking signal. Further, one to three Input/O...

A method and apparatus for reducing storage requirements for display data on a computer system. Data objects to be displayed are organized into display lists and each data object includes an object type, such as text, graphic, and image. The data objects are rasterized into an uncompressed band buffer and divided into non-intersecting bitmap regions each identified with one or more object types. Each non-empty region is assigned a compression algorithm dependent upon the type of the region and s...

Disclosed is a text justification program (20) that runs on a computer (22) in accordance with the invention. The text justification program provides an improved method for justifying text by introducing random character modifications throughout the text so that characters modified for justification purposes do not stand out.

A computer-implemented apparatus and method for generating an output digital font from a base font and one or more font descriptor files. In one example, the method involves, the steps of retrieving from memory a file containing instructions and data for a generic base font; retrieving from memory a font descriptor file containing specifications for operating upon the base font to produce the desired output font; and then generating the output font by performing operations upon the base font in ...

A reader for displaying an electronic document stored 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) ...
