DESCRIPTION

64       Each of the mlib_GraphicsDrawEllipse_*()  functions  draws  an  ellipse
65       with  the center at (x, y), major semiaxis a, and minor semiaxis b. The
66       angle of the major semiaxis is t counterclockwise from the X axis.
67
68
69       Each of the mlib_GraphicsDrawEllipse_X_*() functions draws  an  ellipse
70       in Xor mode as follows:
71
72             data[x,y] ^= c ^ c2
73
74
75
76       Each  of  the mlib_GraphicsDrawEllipse_A_*() functions draws an ellipse
77       with antialiasing.
78
79
80       Each of the mlib_GraphicsDrawEllipse_B_*() functions draws  an  ellipse
81       with alpha blending as follows:
82
83             data[x,y] = (data[x,y] * (255 - alpha) + c * alpha) / 255
84
85
86
87       Each  of  the mlib_GraphicsDrawEllipse_A_*() functions draws an ellipse
88       with antialiasing and alpha blending.
89

PARAMETERS

91       Each of the functions takes some of the following arguments:
92
93       buffer    Pointer to the image into which the function is drawing.
94
95
96       x         X coordinate of the center.
97
98
99       y         Y coordinate of the center.
100
101
102       a         Major semiaxis of the ellipse.
103
104
105       b         Minor semiaxis of the ellipse.
106
107
108       t         Angle of major semiaxis in radians.
109
110
111       c         Color used in the drawing.
112
113
114       c2        Alternation color.
115
116
117       alpha     Alpha value for blending. 0 ≤ alpha ≤ 255.
118
119

RETURN VALUES

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