in single-precision floating-point format.
|
Float(float x1, float y1, float cx, float cy, float x2, float y2) - Constructs a new QuadCurve2D that stores its coordinate values
in single-precision floating-point format, specifying the
initial position of each point.
|
Rectangle2D | getBounds2D() - Determines the smallest rectangle that encloses the
curve’s start, end and control point.
|
Point2D | getCtrlPt() - Returns the curve’s control point.
|
double | getCtrlX() - Returns the x coordinate of the curve’s control
point.

ctrlx
public float ctrlx
The x coordinate of the curve’s control point.
ctrly
public float ctrly
The y coordinate of the curve’s control point.
x1
public float x1
The x coordinate of the curve’s start point.
x2
public float x2
The x coordinate of the curve’s end point.
y1
public float y1
The y coordinate of the curve’s start point.
y2
public float y2
The y coordinate of the curve’s end point.
Float
public Float()
Constructs a new QuadCurve2D that stores its coordinate values
in single-precision floating-point format. All points are
initially at position (0, 0).
Float
public Float(float x1,
float y1,
float cx,
float cy,
float x2,
float y2)
Constructs a new QuadCurve2D that stores its coordinate values
in single-precision floating-point format, specifying the
initial position of each point.
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.
getBounds2D
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.
