IInkRenderer::SetViewTransform
4/8/2010
Sets the IInkTransform object that represents the view transform that is used to render ink for the IInkRenderer object.
Syntax
HRESULT SetViewTransform(
[in] IInkTransform *viewTransform
);
Parameters
viewTransform
The IInkTransform object that represents the geometric transformation — rotation, scaling, shear, and reflection — values to use to transform the stroke coordinates within the ink space.A NULL value for the viewTransform parameter correlates to the identity transform.
Return Value
| HRESULT value | Description |
|---|---|
S_OK |
Success. |
E_POINTER |
A parameter contained an invalid pointer. |
E_INVALIDARG |
viewTransform does not point to a compatible IInkTransform object. |
E_INK_EXCEPTION |
An exception occurred inside the method. |
Remarks
The transformation applies to both the points and pen width. The pen width is calculated by multiplying the specified pen width (or default of 53, if unspecified) by the square root of the determinant of the view transform.
To retrieve the view transform, use IInkRenderer::GetViewTransform.
View transformation occurs after object transformation. For more information, see IInkRenderer::SetObjectTransform.
