Constructor Detail

LineToVertical

public LineToVertical()

Creates a vertical line PathCommand. Defaults to absolute.

LineToVertical

public LineToVertical(double y)

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

Parameters:

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

LineToVertical

public LineToVertical(double y,
              boolean relative)

Creates a vertical line PathCommand using the given coordinates.

Parameters:

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

relative - true if the command is relative

LineToVertical

public LineToVertical(LineToVertical vertical)

Creates a copy of the given vertical line PathCommand.

Parameters:

vertical - the command to be copied

Method Detail

copy

public LineToVertical 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

getY

public double getY()

Returns the y-coordinate of the end point of the command.

Returns:

the y-coordinate of the end point of the command

nearEqual

public boolean nearEqual(PathCommand command)

Description copied from class: PathCommand

Determines equality of two commands using rounded values.

Specified by:

setY

public void setY(double y)

Sets the y-coordinate of the end point of the command.

Parameters:

y - the y-coordinate of the end point of the command

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 PathCommand

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
