Constructor Detail

Point

public Point(double x,
     double y)

Initializes a point with its coordinates and a default drawing color (strong gray).

Parameters:

x - the x coordinate (in the map reference).

y - the y coordinate (in the map reference).

Point

public Point(double x,
     double y,
     java.awt.Color dc)

Initializes a point with its coordinates and drawing color.

Parameters:

x - the x coordinate (in the map reference).

y - the y coordinate (in the map reference).

dc - the drawing color.

Method Detail

setSize

public void setSize(int size)

Sets the size of the symbol to display.

Parameters:

size - the size (in pixels).

setShape

public void setShape(int shape)

Sets the symbol to display (see the shape constants).

Parameters:

shape - the symbol to display (cross, circle, square...).

draw

public void draw(java.awt.Graphics2D g2d,
        CoordinateConverter converter)

Description copied from interface: GraphicalPrimitive

The function that draws the primitive

Specified by:

draw in interface GraphicalPrimitive

Parameters:

g2d - the Graphics2D object on which the shape must be drawn.

converter - the coordinate converter used to convert the primitive's coordinates into the screen (hence Graphics2D) coordinates.

getX

public double getX()

Gets the x coordinate of the point.

Returns:

the x coordinate (in the map reference).

getY

public double getY()

Gets the y coordinate of the point.

Returns:

the y coordinate (in the map reference).

getBoundingBox

public BoundingBox getBoundingBox()

Description copied from interface: GraphicalPrimitive

Computes the bounding box of the graphical primitive.

Specified by:

getBoundingBox in interface GraphicalPrimitive

Returns:

the bounding box of the primitive.
