Functions
 
Name 
Description 
 
Arc 
Draws the octant arc of the beveled figure with the given centers, radii and octant mask. When octant = 0xFF and the following are true:
  1. xL = xR, yT = yB , r1 = 0 and r2 = z, a filled circle is drawn with a radius of z.
  2. radii have values (where r1 < r2), a full ring with thickness of (r2-r1) is drawn.
  3. 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,... more 
 
DrawArc 
This renders an arc with from startAngle to endAngle with the thickness of r2-r1. The function returns 1 when the arc is rendered successfuly and returns a 0 when it is not yet finished. The next call to the function will continue the rendering. 
 
Bevel 
Draws a beveled figure on the screen. When x1 = x2 and y1 = y2, a circular object is drawn. When x1 < x2 and y1 < y2 and rad (radius) = 0, a rectangular object is drawn. 
 
FillBevel 
Draws a filled beveled figure on the screen. For a filled circular object x1 = x2 and y1 = y2. For a filled rectangular object radius = 0.
