The line drawing processor, in line drawing processing method

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of facilitating execution of precise area separation based on a drawn line.;SOLUTION: The line drawing processor 100 includes a core line extraction part 21 for extracting a core line CL1 from a line drawing, a terminal point extraction part 22 for extracting a terminal point TP1 of the core line CL1, and an extension direction determining part 24 for determining an injection direction SD injected from the terminal point TP1, based on a drawing direction DD of the core line CL1 continued up to the terminal point, and a curving direction CD for curving an extension direction ED injected along the injection direction SD, to a prescribed direction, as the extension directions ED of extending an extension line EL from the terminal point TP1.;COPYRIGHT: (C)2012,JPO&INPIT
