m:Nullable<float> -> unit
function BeginFigure(
x : double,
y : double,
z : Nullable<double>,
m : Nullable<double>
)
参数
- x
类型：System.Double
A double that specifies the x-coordinate of the starting endpoint of a geometry instance.
- y
类型：System.Double
A double that specifies the y-coordinate of the starting endpoint of a geometry instance.
- z
类型：System.Nullable<Double>
A double that specifies the z-coordinate of the starting endpoint of a geometry instance. Is Nullable.
- m
类型：System.Nullable<Double>
A double that specifies the measure for the point. Is Nullable.
注释
A geometry instance can be drawn with a single stroke of a pen.
Use this method together with the EndFigure() method.
