画线：
ID2D1RenderTarget::DrawLine
virtual void DrawLine(
D2D1_POINT_2F point0,//起点
D2D1_POINT_2F point1,//终点
[in] ID2D1Brush *brush,
FLOAT strokeWidth = 1.0f,//线条粗细
[in, optional] ID2D1StrokeStyle *strokeStyle = NULL//可省略
) = 0;
椭圆：
struct D2D1_ELLIPSE {
D2D1_POINT_2F point;
FLOAT radiusX;
FLOAT radiusY;
};
矩形：
圆角矩形：
struct D2D1_ROUNDED_RECT {
D2D1_RECT_F rect;
FLOAT radiusX;
FLOAT radiusY;
};
画轮廓：
ID2D1RenderTarget::DrawEllipse
void DrawEllipse(
[ref] const D2D1_ELLIPSE &ellipse,
[in] ID2D1Brush *brush,
FLOAT strokeWidth = 1.0f,
[in, optional] ID2D1StrokeStyle *strokeStyle = NULL
);
ID2D1RenderTarget::DrawRectangle
void DrawRectangle(
[ref] const D2D1_RECT_F &rect,
[in] ID2D1Brush *brush,
FLOAT strokeWidth = 1.0f,
[in, optional] ID2D1StrokeStyle *strokeStyle = NULL
);
ID2D1RenderTarget::DrawRoundedRectangle
void DrawRoundedRectangle(
[ref] const D2D1_ROUNDED_RECT &roundedRect,
[in] ID2D1Brush *brush,
FLOAT strokeWidth = 1.0f,
[in, optional] ID2D1StrokeStyle *strokeStyle = NULL
);
填充：
ID2D1RenderTarget::FillEllipse
void FillEllipse(
[ref] const D2D1_ELLIPSE &ellipse,
[in] ID2D1Brush *brush
);
ID2D1RenderTarget::FillRectangle
void FillRectangle(
[ref] const D2D1_RECT_F &rect,
[in] ID2D1Brush *brush
);
ID2D1RenderTarget::FillRoundedRectangle
void FillRoundedRectangle(
[ref] const D2D1_ROUNDED_RECT &roundedRect,
[in] ID2D1Brush *brush
);
