IInkRenderer::GetViewTransform
4/8/2010
Gets the IInkTransform object that represents the IInkRenderer's view transform.
Syntax
HRESULT GetViewTransform(
[in] IInkTransform *viewTransform
);
Parameters
- viewTransform
Gets the matrix that represents the geometric transformation — rotation, scaling, shear, and reflection — values to use to transform the stroke coordinates within the ink space. The transformation applies to both the points and pen width. View transformation occurs after object transformation.
Return Value
| HRESULT value | Description |
|---|---|
S_OK |
Success. |
E_POINTER |
A parameter contained an invalid pointer. |
E_INK_EXCEPTION |
An exception occurred inside the method. |
Remarks
Any translations applied to this transform should be in ink space units (1 unit = .01mm).
Adjusting the view transform is analogous to adjusting the zoom factor on the ink rendering.
To set the view transform, use IInkRenderer::SetViewTransform.
View transformation occurs after object transformation. For more information, see IInkRenderer::GetObjectTransform.
