DrawQuarterArc Method [Visio 2003 SDK Documentation]

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

objRet = object.DrawQuarterArc(xBegin, yBegin, xEnd, yEnd, SweepFlag)

objRet    The new Shape object.

object   Required. An expression that returns a Master, Page, or Shape object in which to draw the new shape.

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 end point of the arc.

yEnd    Required Double. The y-coordinate of the end point of the arc.

SweepFlag    Required VisArcSweepFlags. The type of arc, concave or convex.

2003

Remarks

The begin and end points 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.

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.

Public Sub DrawQuarterArc_Example

    Dim vsoShape As Visio.Shape
    Set vsoShape = ActivePage.DrawQuarterArc(3, 3, 6, 8, visArcSweepFlagConcave)

End Sub
