Patent ID: 7554552

Claim:
A method of generating at least one colored vector surrounded by a dark contour on a colored background, comprising: displaying a colored vector surrounded by a dark contour on a colored background on a matrix screen of a display device composed of pixels; and setting the color of the pixels using three colorimetric components, wherein each colorimetric component of each pixel of the vector is proportional to either a first mixing law or a second mixing law; wherein the first mixing law is applied when the distance from the center of the pixel to the center of the vector is less than a distance d LIMIT representative of the thickness of the vector, the first mixing law based on a colorimetric component representative of the color of the vector and a first transparency law dependent on said distance from the center of the pixel to the center of the vector; and wherein the second mixing law is applied when the distance from the center of the pixel to the center of the vector is greater than the distance d LIMIT representative of the thickness of the vector, the second mixing law comprising a sum of: the first mixing law; an additional function depending on a colorimetric component representative of the color of the background and a second transparency law dependent on said distance from the center of the pixel to the center of the vector.
