All Implemented Interfaces:

Shape, Serializable, Cloneable

public class RelativeGeneralPath
extends Object
implements Shape, Cloneable, Serializable

GeneralPath decorator that adjusts all shape pathing according to specified bounds and orientation. It is used to simplify shape construction code whenever bounds and/or orientation have to be taken into account

Constructor Detail

RelativeGeneralPath

public RelativeGeneralPath(Rectangle bounds)

Constructs new RelativeGeneralPath.

Parameters:

bounds - additional bounds

RelativeGeneralPath

public RelativeGeneralPath(Rectangle bounds,
                           boolean ltr)

Constructs new RelativeGeneralPath.

Parameters:

bounds - additional bounds

Method Detail

moveTo

public final void moveTo(float x,
                         float y)

Adds a point to the path by moving to the specified coordinates.

Parameters:

x - X coordinate

y - Y coordinate

lineTo

public final void lineTo(float x,
                         float y)

Adds a point to the path by drawing a straight line from the current coordinates to the new specified coordinates.

Parameters:

x - X coordinate

y - Y coordinate

quadTo

public final void quadTo(float x1,
                         float y1,
                         float x2,
                         float y2)

Adds a curved segment, defined by two new points, to the path by drawing a Quadratic curve that intersects both the current coordinates and the specified coordinates (x2,y2), using the specified point (x1,y1) as a quadratic parametric control point.

Parameters:

x1 - X coordinate of the quadratic control point

y1 - Y coordinate of the quadratic control point

x2 - X coordinate of the final end point

y2 - Y coordinate of the final end point

curveTo

public final void curveTo(float x1,
                          float y1,
                          float x2,
                          float y2,
                          float x3,
                          float y3)

Adds a curved segment, defined by three new points, to the path by drawing a Bezier curve that intersects both the current coordinates and the specified coordinates (x3,y3), using the specified points (x1,y1) and (x2,y2) as Bezier control points. All coordinates are specified in float precision.

Parameters:

x1 - X coordinate of the first Bezier control point

y1 - Y coordinate of the first Bezier control point

x2 - X coordinate of the second Bezier control point

y2 - Y coordinate of the second Bezier control point

x3 - X coordinate of the final end point

y3 - Y coordinate of the final end point

closePath

public final void closePath()

Closes the current subpath by drawing a straight line back to the coordinates of the last moveTo. If the path is already closed then this method has no effect.

orientX

protected float orientX(float x)

Returns X coordinate oriented according to ltr orientation.

Parameters:

x - X coordinate to orient

Returns:

X coordinate oriented according to ltr orientation
