Shape.FitCurve method (Visio)

  • Article

Reduces the number of geometry segments in a shape or shapes by replacing them with similar spline, arc, and line segments that approximate the paths of the initial segments. Typically, this reduces the number of segments in the shape.

Syntax

expression. FitCurve( _Tolerance_ , _Flags_ )

expression A variable that represents a Shape object.

Parameters

Name Required/Optional Data type Description
Tolerance Required Double How closely the resulting paths must match the shape's original paths.
Flags Required Integer Flags that influence how the shape is drawn.

Return value

Nothing

Remarks

The FitCurve method of a Selection object optimizes each of the shapes in the selection. It does not combine the selected shapes into a single shape.

The paths resulting from the FitCurve method fall within the given tolerance of the initial paths. Tolerance should be in internal drawing units (inches). To match the initial paths exactly, specify a tolerance of zero (0).

The Flags argument is a bitmask that specifies options for optimizing the paths. Its value should either be zero or a combination of one or more of the following values.

Constant Value Description
visSplinePeriodic &H1 Produce periodic splines if appropriate.
visSplineDoCircles &H2 Recognize circular segments in the shape(s) and generate circular arcs instead of spline rows for those segments.
visSplineAbrupt &H4 Break the resulting splines whenever an abrupt change of direction or curvature in a path is detected.
