mediaLib Library Functions            mlib_GraphicsDrawArc(3MLIB)



     mlib_status mlib_GraphicsDrawArc_AB_32(mlib_image *buffer, mlib_s16 x,
          mlib_s16 y, mlib_s32 r, mlib_f32 t1, mlib_f32 t2, mlib_s32 c,
          mlib_s32 a);


DESCRIPTION
     Each of the mlib_GraphicsDrawArc_*() functions draws an  arc
     with the center at (x, y), radius r, start angle t1, and end
     angle t2.


     Each of the mlib_GraphicsDrawArc_X_*()  functions  draws  an
     arc in Xor mode as follows:

           data[x,y] ^= c ^ c2



     Each of the mlib_GraphicsDrawArc_A_*()  functions  draws  an
     arc with antialiasing.


     Each of the mlib_GraphicsDrawArc_B_*()  functions  draws  an
     arc with alpha blending as follows:

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



     Each of the mlib_GraphicsDrawArc_AB_*() functions  draws  an
     arc 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.


     t1        Start angle of the arc in radians.

     t2        End angle of the arc in radians.


     c         Color used in the drawing.


     c2        Alternation color.


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


RETURN VALUES
     Each of the functions returns  MLIB_SUCCESS  if  successful.
     Otherwise it returns MLIB_FAILURE.
