Master.DrawQuarterArc Method

  • Article
Visio Automation Reference

Creates a shape whose path consists of an elliptical arc defined by the two points and the flag passed in as arguments.

Version Information
 Version Added:  Visio 2003

Syntax

expression.DrawQuarterArc(xBegin, yBegin, xEnd, yEnd, SweepFlag)

expression   A variable that represents a Master object.

Parameters

Name Required/Optional Data Type Description
xBegin Required Double The x-coordinate of the begin point of the arc.
yBegin Required Double The y-coordinate of the begin point of the arc.
xEnd Required Double The x-coordinate of the endpoint of the arc.
yEnd Required Double The y-coordinate of the endpoint of the arc.
SweepFlag Required VisArcSweepFlags The type of arc, concave or convex.

Return Value
Shape

Remarks

The begin and endpoints define the bounding rectangle of the arc, and the SweepFlag argument determines which of the two possible arcs within the bounding rectangle is drawn. The bounding rectangle is always aligned to the page coordinate system; that is, the x-axis of the ellipse is parallel to the x-axis of the page.

The following possible values for the SweepFlag argument are declared in VisArcSweepFlags in the Visio type library.

Constant Value Description

visArcSweepFlagConcave

0

Concave arc

visArcSweepFlagConvex

1

Convex arc

If SweepFlag is visArcSweepFlagConcave, the line joining the center of the ellipse to the arc sweeps through decreasing angles; if it is visArcSweepFlagConvex, it sweeps through increasing angles.

Example

This Microsoft Visual Basic for Applications (VBA) macro shows how to use the DrawQuarterArc method to draw a concave arc on the drawing page.
