Member Function Documentation

void CanvasPoint::draw (  Graphics    g )  [inline, virtual]
 

Draw CanvasObject on 'g', using internal CCS values.

Reimplemented from CanvasObject. 

00060     {
00061         setupDrawMode(g);
00062         if (!getTransformOK()) {
00063             transformICStoCCS();
00064         }
00065         g.fillRect(getX1Ccs(), getY1Ccs(), getWidthCcs(), getHeightCcs());
00066     }

Object CanvasPoint::clone (    )  [inline, virtual]

00072         if (hasNoColor) {
00073             color = NO_COLOR;

Resize CanvasObject to width 'w' and height 'h'.

Parameters are assumed Image Coordinate System values.

Reimplemented from ScribbleObject.
