IPC: G09G5/24
Filed: 1992-03-04
Abstract: PURPOSE:To increase the drawing speed of a stroke character by outputting the component values of vectors constituting the stroke character as constants to a dot generating means. CONSTITUTION:A stroke character generator 20 is composed of a processor 24 and a dot generator 26. The processor 24 specify a stroke character corresponding to a code being input, and outputs the component values of vectors constituting the character to the dot generator 26 as constants. The dot generator 26 generates the coordinate values of respective dots corresponding to the constant values in the same way as a conventional dot generator. That is, the processor 24 specifies the stroke character corresponding to the code being input, and supplies the respective component values to the dot generator 26 as the constants, being different from a conventional processor which calculates the respective component values based on the coordinate values of the starting points and the terminating points of the vectors.

Title: Smoothing process method for graphic data
Inventor: NAKAYAMA AKIHIRO
IPC: G05B19/4097
Filed: 1989-02-28
Abstract: PURPOSE:To attain a smoothing process in a form faithful to an original drawing by recording the data on an approximate line after obtaining the approximate line or an approximate circular arc by the least squares method for each approximate section based on the middle points between all apexes adjacent to each other in the approximate sections and then after obtaining the coordinates of an intersecting point between an approximate line satisfying the set conditions and its adjacent approximate section. CONSTITUTION:An approximate section deciding part 2 decides an approximate section based on the read graphic data and a vector changing pattern. A middle point calculating part 3 obtains the middle points between all apexes adjacent to each other in the obtained approxi mate section. A straight line/circular arc approximating part 4 obtains an approximate straight line or an approximate circular arc by the minimum square method based on each middle point. An approximate line evaluating part 5 shortens the approximate section and repeats this process to decide an approximate line that satisfies the set conditions if the set conditions are not satisfied. Then a data writing part 7 records the data on the approximate line together with the coordinates of an intersecting point between the approximate line satisfying the set conditions and that of an adjacent approximate section. Thus a smoothing process faithful to an original drawing is attained with no averaging carried out between apexes of a graphic.
