Vector image drawing device, vector image drawing method, and recording medium

摘要

A vector image drawing device has the following configuration. A contour generation unit (104), based on vector data, generates contour data that represents the starting pixels on a scan line in a drawing area where fill-in starts, and the ending pixels where fill-in ends. An outline buffer (106) stores the number of starting or ending pixels in the contour data for fill-in for each drawn pixel. An error judgment unit (2), when storing the contour data in the outline buffer (106), determines in which pixel there is overflow in the outline buffer of contour data. A pixel position transfer unit (3) adds the numerical value of the overflow portion of a pixel that the error judgment unit (2) determined to have overflow to the numerical value of contour data that corresponds to a pixel.
