Contour detection finds the outline of a pattern piece in an image and turns it into a closed curve.
PatternScan Pro detects the contour when the piece is cut out and lies free on an even, darker surface. On an uncut multi-size sheet there is no free outline to find, and you draw the contour yourself in the editor instead.

Digitize sewing patterns without tracing.
