Overview

The Draw Module provides an implementation of PostScript type drawing. By grouping lines, curves and moves using a user-defined co-ordinate system, they can be manipulated as one object. This object is called a path.

A path can be manipulated in a manner of different ways. A comprehensive list of options is provided below:

• Rotation, scaling and translation of the path
• Thickness of a line
• Description of dots and dashes for a line
• Joins between lines can be mitred, round or bevelled
• Leading or trailing ends of a line can have the following shapes; butt, round, squared or triangled
• Filling of arbitrary shapes
• Fill the interior of a shape

A path can be manipulated directly on screen or in memory using different sets of SWIs.
