DESCRIPTION

57       Each  of  the mlib_GraphicsDrawCircle_*() functions draws a circle with
58       the center at (x, y) and radius r.
59
60
61       Each of the mlib_GraphicsDrawCircle_X_*() functions draws a  circle  in
62       Xor mode as follows:
63
64             data[x,y] ^= c ^ c2
65
66
67
68       Each of the mlib_GraphicsDrawCircle_A_*() functions draws a circle with
69       antialiasing.
70
71
72       Each of the mlib_GraphicsDrawCircle_B_*() functions draws a circle with
73       alpha blending as follows:
74
75             data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
76
77
78
79       Each  of  the  mlib_GraphicsDrawCircle_AB_*()  functions draws a circle
80       with antialiasing and alpha blending.
81

PARAMETERS

83       Each of the functions takes some of the following arguments:
84
85       buffer    Pointer to the image into which the function is drawing.
86
87
88       x         X coordinate of the center.
89
90
91       y         Y coordinate of the center.
92
93
94       r         Radius of the arc.
95
96
97       c         Color used in the drawing.
98
99
100       c2        Alternation color.
101
102
103       a         Alpha value for blending. 0 ≤ a ≤ 255.
104
105

RETURN VALUES

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