SYNOPSIS

       #include <mlib.h>

       mlib_status mlib_GraphicsDrawCircle_8(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 r, mlib_s32 c);

       mlib_status mlib_GraphicsDrawCircle_32(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 r, mlib_s32 c);

       mlib_status mlib_GraphicsDrawCircle_X_8(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 r, mlib_s32 c, mlib_s32 c2);

       mlib_status mlib_GraphicsDrawCircle_X_32(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 r, mlib_s32 c, mlib_s32 c2);

       mlib_status mlib_GraphicsDrawCircle_A_8(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 r, mlib_s32 c);

       mlib_status mlib_GraphicsDrawCircle_A_32(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 r, mlib_s32 c);

       mlib_status mlib_GraphicsDrawCircle_B_8(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 r, mlib_s32 c, mlib_s32 a);

       mlib_status mlib_GraphicsDrawCircle_B_32(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 r, mlib_s32 c, mlib_s32 a);

       mlib_status mlib_GraphicsDrawCircle_AB_8(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 r, mlib_s32 c, mlib_s32 a);

       mlib_status mlib_GraphicsDrawCircle_AB_32(mlib_image *buffer, mlib_s16 x, mlib_s16 y, mlib_s32 r, mlib_s32 c, mlib_s32 a);

       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.

       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.

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