Abstract
The field of the invention is that of graphical libraries providing graphical functions used for the drawing of symbologic images. One of the fields of favored application is the generation of symbologic images for the piloting of aircraft. The object of the invention is to propose a method of graphical generation of a colored vector surrounded by a dark contour (H) on a background likewise colored as a single drawing, making it possible to preserve the function of antialiasing. The method uses two different mixing laws dependent on the position of the pixel of the vector with respect to the central axis of the vector. This method presents the following advantages:
