WORD Arc( SHORT xL, SHORT yT, SHORT xR, SHORT yB, SHORT r1, SHORT r2, BYTE octant );
Overview
Draws the octant arc of the beveled figure with the given centers, radii and octant mask. When octant = 0xFF and the following are true:
- xL = xR, yT = yB , r1 = 0 and r2 = z, a filled circle is drawn with a radius of z.
- radii have values (where r1 < r2), a full ring with thickness of (r2-r1) is drawn.
- xL != xR, yT != yB , r1 = 0 and r2 = 0 (where xR > xL and yB > yT) a rectangle is drawn. xL, yT specifies the left top corner and xR, yB specifies the right bottom corner.
