Class TransformedFigureTutorial
java.lang.Object
|
+--diva.canvas.tutorial.TransformedFigureTutorial
- public class TransformedFigureTutorial
- extends java.lang.Object
An example showing how to make custom figures that contain
their own AffineTransform. In the FigureTutorial class, we
showed how to make a custom figure, and how to transform the
various 2D shapes in the paint() method. Here, we will use
an AffineTransform to do the same thing. This technique is
a little more work to figure out how to do, but it probably
better if your figure has more than a couple of Shapes in it.
Transforms are a little tricky to get right, so the Diva
Canvas provides a class, TransformContext, that you need to use
to give a figure its own transform. Each instance of TransformContext
contains a single AffineTransform, and a bunch of methods that
deal with it. See the class documentation for
TransformedFigureTutorial.CloudFigure for more details.

of TransformContext to position that image. |
