Kamaelia Cat logo renderer

Renderer for the topology viewer framework that renders a Kamaelia cat logo to the top left corner on rendering pass 10.

Example Usage

Create a topology viewer component that also renders 'ExtraWindowFurniture' to the display surface:

TopologyViewer( extraDrawing = ExtraWindowFurniture(),
                ...
              ).activate()

How does it work?

Instances of this class provide a render() generator that renders a Kamaelia cat logo at coordinates (8,8) to the specified pygame surface. The cat logo is scaled so its longest dimension (width or height) is 64 pixels.

Rendering is performed by the generator, returned when the render() method is called. Its behaviour is that needed for the framework for multi-pass rendering that is used by TopologyViewer.

The generator yields the number of the rendering pass it wishes to be next on next. Each time it is subsequently called, it performs the rendering required for that pass. It then yields the number of the next required pass or completes if there is no more rendering required.

An setOffset() method is also implemented to allow the particles coordinates to be offset. This therefore makes it possible to scroll the particles around the display surface.

See TopologyViewer for more details.
