Each of the mlib_GraphicsFillEllipse_*() functions draws a filled ellipse with the center at (x, y), major semiaxis a, and minor semiaxis
b. The angle of the major semiaxis is t counterclockwise from the X axis.
Each of the mlib_GraphicsFillEllipse_X_*() functions draws a filled ellipse in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsFillEllipse_A_*() functions draws a filled ellipse with antialiasing.
Each of the mlib_GraphicsFillEllipse_B_*() functions draws a filled ellipse with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - alpha) + c * alpha) / 255
Each of the mlib_GraphicsFillEllipse_A_*() functions draws a filled ellipse 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.
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.
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
