Detailed Description

Abstract Device Context.

A Device Context is used to maintain the state of the graphics drawing system. Defining your drawing code in terms of the Abstract Device Context allows the drawing commands to be rendered on different types of surfaces, such as windows and images (FXDCWindow), or on paper (FXDCPrint). WYSYWYG may be obtained by using the same identical drawing code in your application regardless of the actual device surface being utilized.
