Method Detail

paint

void paint(java.awt.Graphics2D g,
           java.awt.geom.AffineTransform worldToScreen,
           double w,
           double h,
           T object)

Perform the painting operations for the given object on the given Graphics.

See Painter.paint(Graphics2D, AffineTransform, double, double) for more information about how the Graphics object is handled among painters.

Parameters:

g - The Graphics used for painting

worldToScreen - The world-to-screen transform. This transform encapsulates the translation, rotation and scaling of the viewer to which this painter belongs.

w - The width of the area, in screen coordinates, in which this painter operates. This is the screen size of the viewer to which this painter belongs.

h - The height of the area, in screen coordinates, in which this painter operates. This is the screen size of the viewer to which this painter belongs.

object - The object to paint. One has to assume that this object may be null, in which case the painting operation will usually be skipped.
