Class QuadCurve2D.Double

public double ctrlx

The x coordinate of the curve’s control point.

public double ctrly

The y coordinate of the curve’s control point.

public double x1

The x coordinate of the curve’s start point.

public double x2

The x coordinate of the curve’s end point.

public double y1

The y coordinate of the curve’s start point.

public double y2

The y coordinate of the curve’s end point.

public Double()

Constructs a new QuadCurve2D that stores its coordinate values in double-precision floating-point format. All points are initially at position (0, 0).

public Double(double x1,
              double y1,
              double cx,
              double cy,
              double x2,
              double y2)

Constructs a new QuadCurve2D that stores its coordinate values in double-precision floating-point format, specifying the initial position of each point.

Parameters:

x1 - the x coordinate of the curve’s start point.

y1 - the y coordinate of the curve’s start point.

cx - the x coordinate of the curve’s control point.

cy - the y coordinate of the curve’s control point.

x2 - the x coordinate of the curve’s end point.

y2 - the y coordinate of the curve’s end point.

public Rectangle2D getBounds2D()

Determines the smallest rectangle that encloses the curve’s start, end and control point. As the illustration below shows, the invisible control point may cause the bounds to be much larger than the area that is actually covered by the curve.

Specified by:
