Параметры

objectTransform
Тип: System.Drawing.Drawing2D.Matrix%
The Matrix object that represents the geometric transformation values—rotation, scaling, shear, and reflection—to use to transform the stroke coordinates within the ink space.

Заметки

The transformation applies to the points, but not the pen width.

Object transformation occurs before view transformation.

Примеры

In this example, the GetObjectTransform is used to obtain the current object 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. Because false is passed to the applyOnPenWidth parameter, the width of the Ink is not scaled. Finally, the SetObjectTransform method is used to restore the original object transform.

' create a Matrix object and obtain the current object transform
Dim origObjectTransform As Matrix = New Matrix()
mInkOverlay.Renderer.GetObjectTransform(origObjectTransform)
' scale the ink (without scaling the ink width)- this affects the object transform
mInkOverlay.Renderer.Scale(2.0F, 2.0F, False)
' later, you can restore the object transform back to the original
mInkOverlay.Renderer.SetObjectTransform(origObjectTransform)

// create a Matrix object and obtain the current object transform
Matrix origObjectTransform = new Matrix();
mInkOverlay.Renderer.GetObjectTransform(ref origObjectTransform);
// scale the ink (without scaling the ink width)- this affects the object transform
mInkOverlay.Renderer.Scale(2.0f, 2.0f, false);
// later, you can restore the object transform back to the original
mInkOverlay.Renderer.SetObjectTransform(origObjectTransform);
