Low-level graphics
(AFL 3.0)


SYNTAX GfxPolygon( x1, y1, x2, y2, ... )
RETURNS NOTHING
FUNCTION Draws a polygon consisting of two or more points (vertices) connected by lines, using the current pen. The system closes the polygon automatically, if necessary, by drawing a line from the last vertex to the first.

This function takes variable number of arguments and accepts up to 12 points (24 arguments = 12 co-ordinate pairs). The number of arguments must be even as each pair represents (x,y) co-ordinates of the vertex.

The polygon is filled with current brush and outline is painted with current pen.

Parameters:

  • x1 - x co-ordinate of first point
  • y1 - y co-ordinate of first point
  • x2 - x co-ordinate of second point
  • y2 - y co-ordinate of second point
  • ...
  • x12 - x co-ordinate of 12th point
  • y12 - y co-ordinate of 12th point
