SYNOPSIS

DESCRIPTION
Each of the mlib_GraphicsDrawCircle_*() functions draws a circle with the center at (x, y) and radius r. Each of the mlib_GraphicsDrawCircle_X_*() functions draws a circle in Xor mode as follows: data[x,y] ^= c ^ c2 Each of the mlib_GraphicsDrawCircle_A_*() functions draws a circle with antialiasing. Each of the mlib_GraphicsDrawCircle_B_*() functions draws a circle with alpha blending as follows: data[x,y] = (data[x,y] * (255 - a) + c * a) / 255 Each of the mlib_GraphicsDrawCircle_AB_*() functions draws a 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.
