NAME
     mlibGraphicsDrawPoint,            mlibGraphicsDrawPoint8,
     mlibGraphicsDrawPoint32,       mlibGraphicsDrawPointX8,
     mlibGraphicsDrawPointX32,     mlibGraphicsDrawPointB8,
     mlibGraphicsDrawPointB32 - draw point

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlibstatus mlibGraphicsDrawPoint8(mlibimage *buffer, mlibs16 x,
          mlibs16 y, mlibs32 c);


     mlibstatus mlibGraphicsDrawPoint32(mlibimage *buffer, mlibs16 x,
          mlibs16 y, mlibs32 c);


     mlibstatus mlibGraphicsDrawPointX8(mlibimage *buffer, mlibs16 x,
          mlibs16 y, mlibs32 c, mlibs32 c2);


     mlibstatus mlibGraphicsDrawPointX32(mlibimage *buffer, mlibs16 x,
          mlibs16 y, mlibs32 c, mlibs32 c2);


     mlibstatus mlibGraphicsDrawPointB8(mlibimage *buffer, mlibs16 x,
          mlibs16 y, mlibs32 c, mlibs32 a);


     mlibstatus mlibGraphicsDrawPointB32(mlibimage *buffer, mlibs16 x,
          mlibs16 y, mlibs32 c, mlibs32 a);


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


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

           data[x,y] ^= c ^ c2



     Each of the mlibGraphicsDrawPointB*() 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          mlibGraphicsDrawPoint(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  MLIBSUCES  if  successful.
     Otherwise it returns MLIBFAILURE.
