Constructor Detail

MoveTo

public MoveTo()

Creates a move PathCommand. Defaults to absolute.

MoveTo

public MoveTo(double x,
      double y)

Creates a move PathCommand using the given coordinates. Defaults to absolute.

Parameters:

x - the x-coordinate of the current point

y - the y-coordinate of the current point

MoveTo

public MoveTo(double x,
      double y,
      boolean relative)

Creates a move PathCommand using the given coordinates.

Parameters:

x - the x-coordinate of the current point

y - the y-coordinate of the current point

relative - true if the command is relative

MoveTo

public MoveTo(MoveTo command)

Creates a copy of the given move PathCommand.

Parameters:

command - the command to be copied

Method Detail

copy

public MoveTo copy()

Description copied from class: PathCommand

Returns a copy of the path command.

Specified by:

copy in class PathCommand

Returns:

a copy of the path command

nearEqual

public boolean nearEqual(PathCommand command)

Description copied from class: PathCommand

Determines equality of two commands using rounded values.

Specified by:

nearEqual in class PathCommand

Parameters:

command - the command to compare

Returns:

true if equal and false otherwise

toAbsolute

public void toAbsolute(PrecisePoint currentPoint,
              PrecisePoint movePoint)

Description copied from class: PathCommand

Converts the path commands to absolute coordinates using the given frame of reference and the last move.

Overrides:

toAbsolute in class EndPointCommand

Parameters:

currentPoint - frame of reference

movePoint - last move point

toCurve

public List<PathCommand> toCurve(PrecisePoint currentPoint,
                        PrecisePoint movePoint,
                        PrecisePoint curvePoint,
                        PrecisePoint quadraticPoint)

Description copied from class: PathCommand

Converts the PathCommand to a CurveTo command. If a MoveTo no conversion takes place, but the current move point is updated.

Specified by:

toCurve in class PathCommand

Parameters:

currentPoint - the current point of the path

movePoint - the frame of reference for the path

curvePoint - the frame of reference for the Bézier

quadraticPoint - the beginning of the last quadratic curve

Returns:

the converted command

toString

public String toString()

Overrides:

toString in class Object

appendTo

public void appendTo(StringBuilder build)

Specified by:

appendTo in class PathCommand
