Print2CAD OCR 2013 - 66
When vectorizing (OCR function not active), a polyline gets drawn along the middle of
a pixel trace or the outline of a pixel area and iteratively smoothed. Then the polyline
gets recognized as a circle, ellipse or spline.
Using the OCR procedure, a pixel image gets recognized or discarded as a symbol based
on its shape.
