          mlib_s16 y, mlib_s32 c, mlib_s32 c2);


     mlib_status mlib_GraphicsDrawPoint_B_8(mlib_image *buffer, mlib_s16 x,
          mlib_s16 y, mlib_s32 c, mlib_s32 a);


     mlib_status mlib_GraphicsDrawPoint_B_32(mlib_image *buffer, mlib_s16 x,

DESCRIPTION
     Each of the  mlib_GraphicsDrawPoint_*()  functions  draws  a
     point at (x,y) in color c.


     Each of the mlib_GraphicsDrawPoint_X_*() functions  draws  a
     point at (x,y) in Xor mode as follows:

           data[x,y] ^= c ^ c2



     Each of the mlib_GraphicsDrawPoint_B_*() functions  draws  a
     point at (x,y) with alpha blending as follows:

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

mediaLib Library Functions          mlib_GraphicsDrawPoint(3MLIB)



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 point.


     y         Y coordinate of the point.


     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.
