參數
- x
型別：System.Double
A double that specifies the x-coordinate of the starting endpoint in a geometry figure.
- y
型別：System.Double
A double that specifies the y-coordinate of the starting endpoint in a geometry figure.
- z
型別：System.Nullable<Double>
A double that specifies the z-coordinate of the starting endpoint in a geometry figure. Is Nullable.
- m
型別：System.Nullable<Double>
A double that specifies the measure for the point. Is Nullable.
實作
IGeometrySink.BeginFigure(Double, Double, Nullable<Double>, Nullable<Double>)
備註
Figure is a geometric object that can be drawn with a single stroke of a pen.
Method must be used together with the EndFigure() method.
