Constructor Detail

LineTo

public LineTo()

Creates a line PathCommand. Defaults to absolute.

LineTo

public LineTo(double x,
              double y)

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

Parameters:

x - the x-coordinate of the end point of the line

y - the y-coordinate of the end point of the line

LineTo

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

Creates a line PathCommand using the given coordinates.

Parameters:

x - the x-coordinate of the end point of the line

y - the y-coordinate of the end point of the line

relative - true if the command is relative

LineTo

public LineTo(LineTo command)

Creates a copy of the given line PathCommand.

Parameters:

command - the command to be copied

Method Detail

copy

public LineTo copy()

Description copied from class: PathCommand

Returns a copy of the path command.

true if equal and false otherwise

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
