Embodiment
In vector font, a Chinese character constitutes to discharge curve by many, a stroke to discharge curve formation Chinese character, and the demonstration of a Chinese character stroke is exactly a demonstration to discharge curve, therefore to realize the demonstration of the tight cunning of Chinese character, just must analyzing to single to discharge curve.
The present invention specifically may further comprise the steps:
1) font is converted to vector font, each stroke of vector font is one to discharge curve;
2) distinguish on the extracted vector curve and the unique point of vectorial extra curvature;
3) unique point on discharge curve is converted into data point, the unique point of vectorial extra curvature is converted into data point according to the Bei Saier curve;
