VC6.0 implement drawing functions, including basic graphics: linear (numerical differential method, the dotted line method, Bresenham line drawing algorithm), round and oval (midpoint drawcircle, Bresenham circle algorithm, Ellipse generating algorithm), area filling ( Edge filling algorithm, the seed filling algorithm, round and oval fill, pattern fill), cutting, line width and line treatment. There are simple graphic change, as well as the realization of simple curves and surfaces, etc.
