Renderer.Rotate Method

Applies a rotation to the view transform.

Definition

Visual Basic .NET	Public Sub Rotate( _ ByVal degrees As Single, _ ByVal point As Point _ )
C#	public void Rotate( float degrees, Point point );
Managed C++	public: void Rotate( float *degrees, Point *point );

Parameters

degrees	System.Single. The degrees by which to rotate clockwise.
point	System.Drawing.Point. The point—in ink space coordinates—around which to rotate.

Examples

[C#]

This C# example saves the current view transform matrix from the Renderer object in the InkCollector object, theInkCollector, and then applies a rotation of 60 degrees to it around the center of the Ink object.

using System.Drawing.Drawing2D;
...
Matrix theOldMatrix = new Matrix();
theInkCollector.Renderer.GetViewTransform(ref theOldMatrix);
Rectangle bounds = theInkCollector.Ink.GetBoundingBox();
Point center = new Point((bounds.Left + bounds.Right) / 2,
    (bounds.Top + bounds.Bottom) / 2);
theInkCollector.Renderer.Rotate(60.0f, center);
...
                

[VB.NET]

This Microsoft® Visual Basic® .NET example saves the current view transform matrix from the Renderer object in the InkCollector object, theInkCollector, and then applies a rotation of 60 degrees to it around the center of the Ink object.

Imports System.Drawing.Drawing2D
...
Dim theOldMatrix As New Matrix()
theInkCollector.Renderer.GetViewTransform(theOldMatrix)
Dim bounds As Rectangle = theInkCollector.Ink.GetBoundingBox()
Dim center As Point = new Point((bounds.Left + bounds.Right) / 2,
    (bounds.Top + bounds.Bottom) / 2)
theInkCollector.Renderer.Rotate(60.0, center)
