  com.livescribe.geom.Shape
      com.livescribe.geom.LineSegment

public class LineSegment
extends Shape

This class describes a line segment with the upper left and lower right points. The width and height are calculated as the difference between the X- and Y-coordinates, respectively. This is similar to a Rectangle and Ellipse.

Constructor Detail

LineSegment

public LineSegment()

Creates a new line segment having both of its points at (0,0).

LineSegment

public LineSegment(int x,
                   int y,
                   int width,
                   int height)

Creates a new line segment having the specified top left coordinate and size.

Parameters:

x - the first X-coordinate

y - the first Y-coordinate

width - the width

height - the height

LineSegment

public LineSegment(int[] v)

Creates a new line segment having the specified points. The array should contain four elements, two (X,Y) pairs.

Parameters:

v - the vertex array

Method Detail

getX

public int getX()

Returns the X-coordinate of the top left corner.

the X-coordinate of the top left corner.

getY

public int getY()

Returns the Y-coordinate of the top left corner.

Returns:

the Y-coordinate of the top left corner.

getWidth

public int getWidth()

Gets the width of this line. This is the difference between the X-coordinates.

Returns:

the line width.

getHeight

public int getHeight()

Gets the height of this line. This is the difference between the Y-coordinates.

Returns:

the line height.

setX

public void setX(int x)

Sets the X-coordinate of the top left corner.

Parameters:

x - the X-coordinate of the top left corner

setY

public void setY(int y)

Sets the Y-coordinate of the top left corner.

Parameters:

y - the Y-coordinate of the top left corner

setWidth

public void setWidth(int width)

Sets the line width.

Parameters:

width - the new width

setHeight
