Shape.DrawQuarterArc method (Visio)
Creates a new shape whose path consists of an elliptical arc defined by the two points and the flag passed in as arguments.
Syntax
expression. DrawQuarterArc( _xBegin_ , _yBegin_ , _xEnd_ , _yEnd_ , _SweepFlag_ )
expression A variable that represents a Shape 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.
Public Sub DrawQuarterArc_Example
Dim vsoShape As Visio.Shape
Set vsoShape = ActivePage.DrawQuarterArc(3, 3, 6, 8, visArcSweepFlagConcave)
End Sub
