DESCRIPTION
Each of the mlib_GraphicsFillArc_*() functions draws a filled arc with the center at (x, y), radius r, start angle t1, and end angle t2.
Each of the mlib_GraphicsFillArc_X_*() functions draws a filled arc in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsFillArc_A_*() functions draws a filled arc with antialiasing.
Each of the mlib_GraphicsFillArc_B_*() functions draws a filled arc with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
Each of the mlib_GraphicsFillArc_AB_*() functions draws a filled arc 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.
r Radius of the arc.
t1 Start angle of the arc in radians.
t2 End angle of the arc in radians.
c Color used in the drawing.
c2 Alternation color.
a Alpha value for blending. 0 <= a <= 255.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
