– Check self-overlapping contours
This function checks whether there are intersections within one contour.
No parameter is needed.
– Check double points Control/Anchor
This function checks whether there are control points very close to anchor
points. This can be part of the design but it can also indicate a digitization
error. Especially if the control point is located on the wrong side of the
anchor point the curve can be very problematic for further conversions. If
the point is within the double point parameter tolerance it will be shifted to
the position of the anchor point.
– Check tangent continuity
This function checks whether two curve sections have tangent continuity at
their joining anchorpoint. If the angle is less than 15 degrees the program
will make the transition continuous by shifting the control point positions.
This function should be used with care and controlled afterwards!
– Check peaks
This function checks whether there are sharp angles within the data. They
can be a design feature, but in many cases it indicates a problem. A peak
parameter is needed.
– Check empty contours
This function checks whether there are contours with area 0 (zero) in the
data. They are simply recognized by having less than 4 digitizations. No
parameter is needed for this function.
– Check zigzags
This function checks another class of problems which might arise from
either digitization errors or from editing mistakes. Zigzags are sequences
of anchor points which form acute angles of opposite direction. A double
point parameter is needed.
– Check sequence of points
This function corrects errors in the sequence of points which prevents
correct showing of the characters. This can for instance occur after the
interpolation of be databases.
