ID2D1SimplifiedGeometrySink::Close method

Closes the geometry sink, indicates whether it is in an error state, and resets the sink's error state.

Syntax


virtual HRESULT Close() = 0;

Parameters

This method has no parameters.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

Do not close the geometry sink while a figure is still in progress; doing so puts the geometry sink in an error state. For the close operation to be successful, there must be one EndFigure call for each call to BeginFigure.

After calling this method, the geometry sink might not be usable. Direct2D implementations of this interface do not allow the geometry sink to be modified after it is closed, but other implementations might not impose this restriction.

Examples

The following example creates an ID2D1PathGeometry, retrieves a sink, and uses it to define an hourglass shape.


ID2D1GeometrySink *pSink = NULL;




// Create a path geometry.
if (SUCCEEDED(hr))
{
    hr = m_pD2DFactory->CreatePathGeometry(&m_pPathGeometry);

    if (SUCCEEDED(hr))
    {
        // Write to the path geometry using the geometry sink.
        hr = m_pPathGeometry->Open(&pSink);

        if (SUCCEEDED(hr))
        {
            pSink->BeginFigure(
                D2D1::Point2F(0, 0),
                D2D1_FIGURE_BEGIN_FILLED
                );

            pSink->AddLine(D2D1::Point2F(200, 0));

            pSink->AddBezier(
                D2D1::BezierSegment(
                    D2D1::Point2F(150, 50),
                    D2D1::Point2F(150, 150),
                    D2D1::Point2F(200, 200))
                );

            pSink->AddLine(D2D1::Point2F(0, 200));

            pSink->AddBezier(
                D2D1::BezierSegment(
                    D2D1::Point2F(50, 150),
                    D2D1::Point2F(50, 50),
                    D2D1::Point2F(0, 0))
                );

            pSink->EndFigure(D2D1_FIGURE_END_CLOSED);

            hr = pSink->Close();
        }
        SafeRelease(&pSink);
    }
}
