mediaLib Library Functions        mlib_GraphicsDrawEllipse(3MLIB)



     mlib_status mlib_GraphicsDrawEllipse_AB_32(mlib_image *buffer, mlib_s16 x,
          mlib_s16 y, mlib_s32 a, mlib_s32 b, mlib_f32 t, mlib_s32 c,
          mlib_s32 alpha);


DESCRIPTION
     Each of the mlib_GraphicsDrawEllipse_*() functions draws  an
     ellipse  with  the  center  at (x, y), major semiaxis a, and
     minor semiaxis b. The angle of the major semiaxis is t coun-
     terclockwise from the X axis.


     Each of the mlib_GraphicsDrawEllipse_X_*()  functions  draws
     an ellipse in Xor mode as follows:

           data[x,y] ^= c ^ c2



     Each of the mlib_GraphicsDrawEllipse_A_*()  functions  draws
     an ellipse with antialiasing.


     Each of the mlib_GraphicsDrawEllipse_B_*()  functions  draws
     an ellipse with alpha blending as follows:

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



     Each of the mlib_GraphicsDrawEllipse_A_*()  functions  draws
     an ellipse 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.


     a         Major semiaxis of the ellipse.


     b         Minor semiaxis of the ellipse.

     t         Angle of major semiaxis in radians.


     c         Color used in the drawing.


     c2        Alternation color.


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


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