Detailed Description

Draw adapter interface used for drawing eVision objects and results.

The interface contains various primitives to draw images and various shapes (line, rectangle, ellipse, polygon). It draws the contours of shapes using a EPen and fills the inside of a shape with a EBrush. It has a default pen (EDrawAdapter.Pen) and default brush (EDrawAdapter.Brush) but they can be overridden using the optional pen and brush arguments of shape primitives. If no default pen and brush are set and no optional pen and brush are specified when calling a shape primitives, the shape will not be drawn. For the "Fill" primitives, no pen will result in no contours being drawn around the shape and no brush is equivalent to the corresponding "Draw" primitive.
