CHARACTER GRAPHIC INPUTTING METHOD FOR GRAPHIC PROCESSOR

摘要

PROBLEM TO BE SOLVED: To simply input a larger amount of characters written on a graphic such as a map with an attribute expressing its geometric shape in an easy-to-see state. SOLUTION: At the time of defining a character graphic by a graphic processor with a graphic processing function, a rotary rectangle 22 in a space occupied by a displayed character graphic is designated by two points expressing the bottom edge of the rectangle 22 and one point on an opposed edge, character data of a character graphic are inputted to obtain attribute information expressing the geometric shape of a character graphic from this rotary rectangle and the number of character data to prepare character graphic data according to this attribute information. The plotting direction of the character graphic is made horizontal when an angle formed by the bottom edge of the rectangle 22 with a horizon is not larger than 45 deg. but made vertical when the angle is larger than 45 deg..
