/*
 * LineStyles illustrates how to set the style when drawing lines using the FSSolidLine
 * class. This example also illustrates the rounded line end and join styles displayed 
 * when a line is rendered by the Flash Player and how the styles can be changed by
 * drawing thin rectangles to represent line segments.
 *
 * To run this example, type the following on a command line:
 *
 *     java LineStyles [--resultDir path]
 *
 * where
 *
 *       resultDir is the directory where the Flash file generated by the example is
 *       written to.
 *
 * The lines and shapes are drawn by specifying the coordinates in pixels. The
 * Transform.COORDINATES_ARE_PIXELS flag controls whether the units are specified in 
 * pixels (true) or twips (false). Similarly the width of a line is controlled by 
 * the Transform.LINE_WIDTHS_ARE_PIXELS flag.
 *
 * To provide the fine degree of control required to draw line segments using rectangles
 * the methods on classes that take coordinates or line widths support an optional argument,
 * direct, which when true, allows the values supplied to be specified in twips overriding 
 * the COORDINATES_ARE_PIXELS and LINE_WIDTHS_ARE_PIXELS flags.
