01. PHOTO DIGITIZER
The photo digitizer can automatically extract the pattern contour, using precise Bezier curves, can identify corners and mark it as reference points, can identify different type of notches (marked or cutted), internal points and internal lines. By convention, the longest internal line found will be declared as grain axis. When the patterns are created inside the office,it is usefull to respect some standard marking procedures, avoiding any manual adjustement of the digitizing results.
