Abstract

본 발명은 도트 매트릭스 칼라 프린터에서 칼라문자의 외곽에 윤곽문자를 중첩시켜 인자하므로서 문자 또는 문구의 강조와 인자형태의 다양성을 확보할 수 있도록 한 윤곽 칼라문자의 인자방법에 관한 것으로 종래의 도트 매트릭스 칼라 프린터에서는 인자되는 문자의 칼라가 단일하고 인자 형태 또는 가변성이 결여되어 있으므로 강조하고자 하는 문자 또는 문구의 표현이 어려운 단점을 해결하기 위한 것이다.The present invention relates to a method of printing an outline color character in which a dot matrix color printer superimposes the outline character on the outer edge of the color character and prints, thereby ensuring the emphasis of the character or phrase and the diversity of the printing form. In the printer, the color of the character to be printed is a single color and lacks the form or variability of the printing.

본 발명은 인자할 문자의 폰트데이타를 이미지 버퍼내에서, 상,하,좌,우로 1비트씩 시프트시키고 논리합 및 배타적 논리합의 편집처리를 하여 외곽 윤곽문자를 구성한후 이 외곽 윤곽문자를 원래의 폰트데이타에 의한 문자에 중첩시켜 인자하므로서 윤곽부가 이루어진 칼라문자를 인자할수 있도록하여 원고의 내용중 강조부분의 용이한 식별과 인자형태의 다양성을 확보할 수 있도록 한 것으로 도트 매트릭스 칼라프린터에 적용한다.According to the present invention, the font data of the character to be printed is shifted by one bit up, down, left, and right in the image buffer, and the outer contour is formed by editing the logical sum and the exclusive logical sum, and then the outer contour is converted into the original font. It prints by superimposing the text by the data so that it can print the color character with the outline, so that it is possible to easily identify the highlighting part of the manuscript and the diversity of the printing form. It is applied to the dot matrix color printer.

Claims

A first process of decoding the font data corresponding to the character to be printed from the font ROM 2 and storing it in the image buffer, and then shifting the font data stored in the image buffer by one bit each up, down, left, and right to perform an OR operation. Thereafter, a second process of constructing the outer contour character by performing exclusive OR with the original font data in the first process, and then printing the original font data stored in the image buffer as color 1 and obtaining the outer contour character obtained in the second process And a third process of superimposing and printing on the characters printed by the original font data without line transfer to color 2.
