public class PureGraphics
extends java.awt.Graphics

Pure Graphics - a Graphics with no ties to any AWT native nonsense. Currently only implemented for Images -- you can draw an Image, but you can't do most of the normal painting/filling operations. Someday I'll implement diagonal line-drawing, polygon-filling, etc. Note that drawLine() works, but only if the line is vertical or horizontal :-)

Method Detail

create

public java.awt.Graphics create()
Create a new Graphics Object based on this one.

Specified by:
create in class java.awt.Graphics

translate

public void translate(int x,
                      int y)
Translates the origin of the graphics context to the point (x, y) in the current coordinate system. Modifies this graphics context so that its new origin corresponds to the point (x, y) in this graphics context's original coordinate system. All coordinates used in subsequent rendering operations on this graphics context will be relative to this new origin.

Specified by:
translate in class java.awt.Graphics
Parameters:
x - the x coordinate.
y - the y coordinate.
Since:
JDK1.0
