### GfxChord - draw a chord

Low-level graphics
(AFL 3.0)

 SYNTAX GfxChord( x1, y1, x2, y2, x3, y3, x4, y4 ) RETURNS NOTHING FUNCTION Draws a chord (a closed figure bounded by the intersection of an ellipse and a line segment). The (x1, y1) and (x2, y2) parameters specify the upper-left and lower-right corners, respectively, of a rectangle bounding the ellipse that is part of the chord. The (x3, y3) and (x4, y4) parameters specify the endpoints of a line that intersects the ellipse. The chord is drawn by using the selected pen and filled by using the selected brush. Parameters x1 - x-coordinate of the upper left corner of the bounding rectangle y1 - y-coordinate of the upper left corner of the bounding rectangle x2 - x-coordinate of the lower right corner of the bounding rectangle y2 - y-coordinate of the lower right corner of the bounding rectangle x3 - x-coordinate of the chord's starting point. y3 - y-coordinate of the chord's starting point. x4 - x-coordinate of the chord's ending point. y4 - y-coordinate of the chord's ending point.
