Shape.FitCurve Method (Visio)

Published: July 16, 2012

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.

Version Added: Visio 4.1

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

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.
