PointF 结构

定义

表示在二维平面中定义点的浮点 x 和 y 坐标的有序对。Represents an ordered pair of floating-point x- and y-coordinates that defines a point in a two-dimensional plane.

注解

若要将PointF转换Point为, 请Point.Round使用Point.Truncate或。To convert a PointF to a Point, use Point.Round or Point.Truncate.

构造函数

PointF(Single, Single)

用指定坐标初始化 PointF 类的新实例。Initializes a new instance of the PointF class with the specified coordinates.

字段

Empty

表示 PointF 类的、成员数据未被初始化的新实例。Represents a new instance of the PointF class with member data left uninitialized.

属性

IsEmpty

获取一个值,该值指示此 PointF 是否为空。Gets a value indicating whether this PointF is empty.

X

获取或设置此 PointF 的 x 坐标。Gets or sets the x-coordinate of this PointF.

Y

获取或设置此 PointF 的 y 坐标。Gets or sets the y-coordinate of this PointF.
