IXpsOMObjectFactory::CreateMatrixTransform method (xpsobjectmodel.h)
Creates an IXpsOMMatrixTransform interface that specifies an affine matrix transform.
Syntax
HRESULT CreateMatrixTransform(
[in] const XPS_MATRIX *matrix,
[out, retval] IXpsOMMatrixTransform **transform
);
Parameters
[in] matrix
The initial matrix to be assigned to the transform.
[out, retval] transform
A pointer to the new IXpsOMMatrixTransform interface.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the table that follows. For information about XPS document API return values that are not listed in this table, see XPS Document Errors.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
matrix or transform is NULL. |
Remarks
The transform specified by this matrix can be applied to the transform property of other XPS objects.
The code example that follows illustrates how this method is used to create a new interface.
IXpsOMMatrixTransform *newInterface;
// The following value is defined outside of
// this example.
XPS_MATRIX newMatrix;
// Note the implicit requirement that CoInitializeEx
// has previously been called from this thread.
hr = CoCreateInstance(
__uuidof(XpsOMObjectFactory),
NULL,
CLSCTX_INPROC_SERVER,
_uuidof(IXpsOMObjectFactory),
reinterpret_cast<LPVOID*>(&xpsFactory)
);
if (SUCCEEDED(hr))
{
hr = xpsFactory->CreateMatrixTransform (
&newMatrix,
&newInterface);
if (SUCCEEDED(hr))
{
// use newInterface
newInterface->Release();
}
xpsFactory->Release();
}
else
{
// evaluate HRESULT error returned in hr
}
