Renderer.GetViewTransform Method
Identifies the Matrix object that represents the object transform that was used to render ink.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)
Syntax
'Declaration
Public Sub GetViewTransform ( _
ByRef viewTransform As Matrix _
)
'Usage
Dim instance As Renderer
Dim viewTransform As Matrix
instance.GetViewTransform(viewTransform)
public void GetViewTransform(
ref Matrix viewTransform
)
public:
void GetViewTransform(
Matrix^% viewTransform
)
public function GetViewTransform(
viewTransform : Matrix
)
Parameters
viewTransform
Type: System.Drawing.Drawing2D.Matrix%The Matrix object that represents the view transform that was used to render ink.
Remarks
The transformation applies to both the points and pen width.
View transformation occurs after object transformation.
Examples
In this example, the GetViewTransform is used to obtain the current view transform matrix from the Renderer object in an InkOverlay object. Then a scaling factor of 2 in both the X and Y dimensions is applied. Finally, the SetViewTransform method is used to restore the original view transform.
' create a Matrix object and obtain the current view transform
Dim origViewTransform As Matrix = New Matrix()
mInkOverlay.Renderer.GetViewTransform(origViewTransform)
' scale the ink - this affects the view transform
mInkOverlay.Renderer.Scale(2.0F, 2.0F)
' later, you can restore the view transform back to the original
mInkOverlay.Renderer.SetViewTransform(origViewTransform)
// create a Matrix object and obtain the current view transform
Matrix origViewTransform = new Matrix();
mInkOverlay.Renderer.GetViewTransform(ref origViewTransform);
// scale the ink - this affects the view transform
mInkOverlay.Renderer.Scale(2.0f, 2.0f);
// later, you can restore the view transform back to the original
mInkOverlay.Renderer.SetViewTransform(origViewTransform);
