mediaLib Library Functions         mlib_GraphicsDrawCircle(3MLIB)



DESCRIPTION
     Each of the mlib_GraphicsDrawCircle_*()  functions  draws  a
     circle with the center at (x, y) and radius r.


     Each of the mlib_GraphicsDrawCircle_X_*() functions draws  a
     circle in Xor mode as follows:

           data[x,y] ^= c ^ c2



     Each of the mlib_GraphicsDrawCircle_A_*() functions draws  a
     circle with antialiasing.


     Each of the mlib_GraphicsDrawCircle_B_*() functions draws  a
     circle with alpha blending as follows:

           data[x,y] = (data[x,y] * (255 - a) + c * a) / 255



     Each of the mlib_GraphicsDrawCircle_AB_*() functions draws a
     circle with antialiasing and alpha blending.

PARAMETERS
     Each of the functions takes some of the following arguments:

     buffer    Pointer to the image into which  the  function  is
               drawing.


     x         X coordinate of the center.


     y         Y coordinate of the center.


     r         Radius of the arc.


     c         Color used in the drawing.


     c2        Alternation color.


     a         Alpha value for blending. 0 < a < 255.
