A Canvas is an area on the screen to which Pictures can be drawn.

Determines where the center of the canvas is located.

The Frame specifies how to create a Canvas.

Utilities for rendering with Java2D

Write an animation as an animated GIF. The GIF file format doesn't support transparency to the degree we need to faithfully render Java2d images. In particular it doesn't support semi-transparent redraw. As a result we just fill with the background color on each frame, if the background is set.

Determines how the Canvas handles drawing multiple Pictures. The default is to clear the Canvas with the Frame 's background color every time a new picture is rendered. Alternatively a different color can be specified. This allows one to blend together pictures while keeping a constant background.
