Title: Character string clip processing system
Inventor: ITO TAKAHIRO
IPC: G06F3/153
Filed: 1988-05-11
Abstract: PURPOSE:To perform the clip processing of a character string outside a display area by performing the clip processing of the character string for a character string frame reference point prior to the display processing of the character string. CONSTITUTION:A graphic form and character display device is equipped with a function for enlargement and coordinate transformation for character vector coordinate values outputted by a character pattern generating device and a function for the clip processing of respective coordinate points after the coordinate transformation, and a means which performs the clip processing of the character string outside the display area by making a clip decision on the character string with character string frame segments is provided. Namely, a character string frame vector is generated before character codes are converted into character coordinate vectors to decide whether or not the corresponding character string is in the display area, and when the character string is all outside the display area, the command processing of the character string is finished without converting the respective character codes into the character coordinate vectors. Consequently, the clip processing of the character string outside the display area is speeded up.
