Method Detail

draw

public void draw(Minnow minnow,
                 java.awt.Component comp,
                 java.awt.Graphics2D g2)

Draws the given Minnow. Fills a simple fish with gradient paint using the paths created in the construtor. The Minnow is drawn facing North in a cell of size (1,1) centered around (0,0) on the drawing surface. (All scaling/rotating has been done beforehand).

Parameters:

minnow - minnow we want to draw

comp - component on which to draw

g2 - drawing surface

draw

public void draw(Locatable obj,
                 java.awt.Component comp,
                 java.awt.Graphics2D g2,
                 java.awt.Rectangle rect)

Draw the given object. Scales and rotates the coordinate appropriately then invokes the simple draw method above that is only responsible for drawing a unit-length Minnow facing North. (Precondition: obj is a Minnow.)

Parameters:

obj - object we want to draw

comp - component on which to draw

g2 - drawing surface

rect - rectangle in which to draw
