Resultantly manual drawing gradually is phased out, for those designers who have no prior experience in the computer operation are concerned, they need to have a kind of two-dimensional graphical tool. Graphics editor system arose to the request for designing planar figures for people who have little knowledge in computer.This paper describes the development process of this system what is studied for the foundation, utilize object-oriented method to analyze, design with computer figure, and adopt Visual C ++ 6.0 as the developing platform. All these have been finished after 1 month or so. It designs to be two-dimensional graphical software with diverse function which operates simply, easy to study, mutual interface friendly graphics editor system and has satisfied some figure users at present with the new demand as well.The following main functions have been realized in this application: It can draw various figures, such as dot, line, circle, arc, parabola and curve, modify them and comprehensive editing. Figure editor includes translation, mirroring, rotating and some similar operations. Comprehensive drawing includes drawing polygon (sealed and arbitrary polygon), round tangent line, round circle contact, line circle contact, some circle contacts and so forth. Meanwhile obtain the point of intersect...
