6.8  dc<%>

A dc<%> object is a drawing context for drawing graphics and text. It represents output devices in a generic way; e.g., a canvas has a drawing context, as does a printer.

The drawing methods, such as draw-rectangle, accept real number values as arguments, but the results are only well-defined when the drawing coordinates are in the range -16383 to 16383. This restriction applies to the coordinates both before and after offsets and scaling factors are applied.
