Abstract
The present invention provides a method and a system for pixelating a vector graphic into an image. First, a vector graphic defined by an arbitrary curve boundary is approximated as a vector graphic of a Manhattan structure, and then a fast algorithm is used to pixelate the approximate Manhattan vector graphic into a two-dimensional image. A process of moving quadrant planes to superimpose on vertices of the vector graphic is replaced with convolution of an image resulting from a template rectangle image and Dirac pulse functions of the vertices of the vector graphic, and a pixelated image of this vector graphic is obtained through convolution of the template rectangle and a sparse image composed of Dirac pulses located at the positions of the vertices of the vector graphic.
