Abstract
The present invention is a character image generation system for generating outline font based on character information and displaying the outline font on a display with a prescribed number of pixels. The character image generation system subdivides a curve expressed by character outline information corresponding to inputted character information, calculates the difference between coordinates at each end of the subdivided curve, compares the difference with a predetermined threshold value and sequentially calculates coordinates for each pixel, based on this comparison result.
Claims20
A character image generation system for generating outline font based on character information including a character code and font information and displaying the outline font on a display with a prescribed number of pixels, comprising:
- an acquisition unit for obtaining the character information;
- a character outline information storage unit for storing character outline information corresponding to the character information;
- a subdivision unit for subdividing a curve expressed by the character outline information;
- a difference calculation unit for calculating a difference between coordinates at each end of the subdivided curve;
- a comparison unit for comparing the difference with a predetermined threshold value;
- and
- an outline coordinate calculation unit for sequentially calculating coordinates for each of the pixels, based on a result of the comparison and specifying the coordinates as the coordinates of an outline of each pixel.
A storage medium on which is recorded a character image generation program for enabling a computer to execute a process of generating outline font, based on character information including a character code and font information and displaying the outline font on a display with a prescribed number of pixels comprising:
- an acquiring process for obtaining the character information;
- an subdivision process for obtaining the character information from a character outline information storage unit for storing character outline information corresponding to the character information and subdividing a curve expressed by the character outline information;
- an difference calculation process for calculating a difference between coordinates at each end of the subdivided curve;
- a comparison process for comparing the difference with a predetermined threshold value;
- and
- an outline coordinate calculation process for sequentially calculating coordinates for each pixel, based on a result of the comparison and specifying the coordinates as the coordinates of an outline of each pixel.
