Stroke.Rotate Method

Rotates the Stroke object around a center point.

Namespace:  Microsoft.Ink
Assembly:  Microsoft.Ink (in Microsoft.Ink.dll)

Syntax

'Declaration
Public Sub Rotate ( _
    degrees As Single, _
    point As Point _
)
'Usage
Dim instance As Stroke 
Dim degrees As Single 
Dim point As Point

instance.Rotate(degrees, point)
public void Rotate(
    float degrees,
    Point point
)
public:
void Rotate(
    float degrees, 
    Point point
)
public function Rotate(
    degrees : float, 
    point : Point
)

Parameters

  • degrees
    Type: System.Single

    The degrees by which to rotate clockwise.

  • point
    Type: System.Drawing.Point

    The point—in ink space coordinates—around which to rotate.

Examples

In this example, each selected Stroke of an InkOverlay object is rotated clockwise 60 degrees. The rotation occurs around the center of the ink control.

Dim inkControl As Control = mInkOverlay.AttachedControl
' get the center of the ink control 
Dim centerPt As Point = New Point(inkControl.Width / 2, inkControl.Height / 2)
Using g As Graphics = inkControl.CreateGraphics()
    ' convert center point to ink space coordinates
    mInkOverlay.Renderer.PixelToInkSpace(g, centerPt)
End Using 
For Each S As Stroke In mInkOverlay.Selection
    S.Rotate(60.0F, centerPt)
Next
Control inkControl = mInkOverlay.AttachedControl;
// get the center of the ink control
Point centerPt = new Point(inkControl.Width / 2, inkControl.Height / 2);
using (Graphics g = inkControl.CreateGraphics())
{
    // convert center point to ink space coordinates
    mInkOverlay.Renderer.PixelToInkSpace(g, ref centerPt);
}
foreach (Stroke S in mInkOverlay.Selection)
{
    S.Rotate(60.0f, centerPt);
}
