ID2D1SimplifiedGeometrySink::BeginFigure method

Starts a new figure at the specified point.

Syntax

void BeginFigure(
  D2D1_POINT_2F     startPoint,
  D2D1_FIGURE_BEGIN figureBegin
);

Parameters

startPoint

Type: D2D1_POINT_2F

The point at which to begin the new figure.

figureBegin

Type: D2D1_FIGURE_BEGIN

Whether the new figure should be hollow or filled.

Return Value

This method does not return a value.

Remarks

If this method is called while a figure is currently in progress, the interface is invalidated and all future methods will fail.

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);
    }
}
