Renderer.SetViewTransform Method

Artículo
12/12/2007

Sets the Matrix object that represents the view transform that is used to render ink.

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

Syntax

'Declaration
Public Sub SetViewTransform ( _
    viewTransform As Matrix _
)
'Usage
Dim instance As Renderer
Dim viewTransform As Matrix

instance.SetViewTransform(viewTransform)

public void SetViewTransform (
    Matrix viewTransform
)

public:
void SetViewTransform (
    Matrix^ viewTransform
)

public void SetViewTransform (
    Matrix viewTransform
)

public function SetViewTransform (
    viewTransform : Matrix
)

Not applicable.

Parameters

viewTransform
The Matrix object that represents the geometric transformation values—rotation, scaling, shear, and reflection—to use to transform the ink from ink space coordinates to logical device context coordinates.

Remarks

The transformation applies to both the points and the pen width.

View transformation occurs after object transformation.

Example

This C# example scales the ink in an InkOverlay object, theInkOverlay, by a factor of 1.5. The example gets the current view transform matrix from the Renderer object, applies the scaling, and then sets it as the Renderer object's new view transform. Note that the pen width also increases by a factor of 1.5.

using System.Drawing.Drawing2D;
...
private void ZoomBy150percent()
        {
            Matrix transformation = new Matrix();
            theInkOverlay.Renderer.GetViewTransform(ref transformation);
            transformation.Scale(1.5f, 1.5f);
            theInkOverlay.Renderer.SetViewTransform(transformation);
        }
