Class CubicCurve2D.Double

public double ctrlx1

The x coordinate of the curve’s first control point.

public double ctrlx2

The x coordinate of the curve’s second control point.

public double ctrly1

The y coordinate of the curve’s first control point.

public double ctrly2

The y coordinate of the curve’s second 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 CubicCurve2D 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 cx1,
              double cy1,
              double cx2,
              double cy2,
              double x2,
              double y2)

Constructs a new CubicCurve2D 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.

cx1 - the x coordinate of the curve’s first control point.

cy1 - the y coordinate of the curve’s first control point.

cx2 - the x coordinate of the curve’s second control point.

cy2 - the y coordinate of the curve’s second 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 points. As the illustration below shows, the invisible control points may cause the bounds to be much larger than the area that is actually covered by the curve.
