Function GraLine() Foundation
Draws a straight line or a portion of a polygon.
GraLine( [<oPS>], [<aStartPoint>], <aEndPoint> ) --> lSuccess
The return value of GraLine() is .T. (true) if the line was drawn, otherwise it is .F. (false). If the return value is .F., the cause of error can be determined using GraError().
The function GraLine() is a graphic primitive which draws a line in a presentation space. In order to draw a line, two points must be specified. If the first point <aStartPoint> is not specified, the line begins at the current pen position. Various line types are available (solid, dashed, dotted, etc.). Line types must be selected before output of the line by calling the function GraSetAttrLine(). After GraLine() returns, the pen is positioned at <aEndPoint>.
