Abstract: A character adjustment method is used for adjusting the character so as to output the character to a second pixel matrix of an output device. The character is designed in a first pixel matrix. The method includes determining a constant, an upper density limit and a lower density limit according to at least one feature value of the output device; performing an interpolation calculation for obtaining a variation parameter according to a density of the character in the first pixel matrix, the constant, the upper density limit and the lower density limit; adjusting the character according to the variation parameter; and outputting the adjusted character to the second pixel matrix by the output device.

Abstract: A font generating system of a display includes a variable converting module, a database and a font generator. The variable converting module is used to receive a first set of font parameters and environmental parameters of the display and to generate a second set of font parameters according to the first set of font parameters and the environmental parameters of the display. The database is used to store font data of a plurality of characters. The font generator is used to generate images of the characters according to the second set of font parameters and font data of the plurality of characters.

Abstract: A special encoded string is generated according to character codes and attributes and/or colors of a plurality of characters in an original string. An alternate encoded string is generated according to the special encoded string. A layout string is generated by laying out a plurality of characters in the alternate encoded string. Then glyphs having attributes and/or colors of a plurality of characters in the layout string are rendered, and the glyphs having the attributes and/or the colors of the plurality characters of the layout string are shown on a display.

Abstract: A structural graph displaying system for generating a new structural graph by changing sub-graphs of an existent structural graph. The displaying system includes a drawing control program for controlling the drawing process of a character, a contour changing program for changing the contour of a stroke along a contour changing direction, and a graph integration program for integrating and outputting the changed contours of all strokes of a character onto a screen. The displaying system further includes a stroke table for storing a stroke ID and corresponding stroke drawing program of each stroke, and a character description file for storing various stroke parameters of each character. The character description file includes an index file and a stroke description table of each character. The index table contains a WID of each character and the addresses of the correspondent stroke description tables.

Abstract: The present invention provides a structural graph display system which makes use of central region distribution of graphic parameters to make index tables to reduce the bit number required for storing each graphic parameter. Each structural graph is formed by at least one sub-graph, and each sub-graph comprises a plurality of parameters which includes a target parameter array. The system further comprises an index table which comprises a set of reference parameter arrays. Each reference parameter array has a corresponding reference index number. The index table further has at least one special index number. Within the graphic description file, each sub-graph of a structural graph has a replacement ID for replacing the target parameter array; if the offset between the target parameter array and any reference parameter array is within a predetermining offset range, the replacement ID is formed by the reference index number of the reference parameter array and a offset array.

Abstract: The present invention provides a matrix character generation system comprising a memory for storing data and programs, a processor for executing the programs stored in the memory, and a screen for displaying matrix graphs generated by the matrix character generation system. The memory comprises a character table for recording all the strokes that form each character, a stroke table for recording the parameters of each stroke, and a graph generation program for displaying the matrix graph of each character on the screen according to the character table and the stroke table. When generating a new character, the graph generation program searches the character table for the stroke IDs of all the strokes of the character and the position of each stroke in the matrix according to the WID of the character. Then it searches the stroke table for the matrix graphic data of each stroke according to the stroke ID of each stroke.

Abstract: The present invention provides a structural graph display system which utilizes index tables and index numbers to replace repeatedly occurred graphic parameters stored in a graphic description file so that overall memory requirement for storing the graphic description file can be substantially reduced. Within the graphic description file, a plurality of structural graphs are stored. Each structural graph comprises at least one sub-graph and each sub-graph contains a plurality of sub-graph parameters for drawing the sub-graph within a target area. One of the sub-graph parameters is defined as a target parameter. An index table of the target parameter is stored in the system which comprises a set of frequently used target parameters, an index number for each frequently used target parameter, and a special index number.
