Description

Each of the mlib_GraphicsFillCircle_*() functions draws a filled circle with the center at (x, y) and radius r.

Each of the mlib_GraphicsFillCircle_X_*() functions draws a filled circle in Xor mode as follows:

    data[x,y] ^= c ^ c2

Each of the mlib_GraphicsFillCircle_A_*() functions draws a filled circle with antialiasing.

Each of the mlib_GraphicsFillCircle_B_*() functions draws a filled circle with alpha blending as follows:

    data[x,y] = (data[x,y] * (255 - a) + c * a) / 255

Each of the mlib_GraphicsFillCircle_AB_*() functions draws a filled circle 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.

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.
