DESCRIPTION
Each of the mlib_GraphicsDrawPointSet_*() and mlib_GraphicsDrawPoly‐
point_*() functions draws a set of points at (x1,y1), (x2,y2), ..., and
(xn,yn).
Each of the mlib_GraphicsDrawPointSet_X_*() and mlib_GraphicsDrawPoly‐
point_X_*() functions draws a set of points at (x1,y1), (x2,y2), ...,
and (xn,yn) in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsDrawPointSet_B_*() and mlib_GraphicsDrawPoly‐
point_B_*() functions draws a set of points at (x1,y1), (x2,y2), ...,
and (xn,yn) with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
The mlib_GraphicsDrawPolypoint_*() functions are aliases of the
mlib_GraphicsDrawPointSet_*() functions.
PARAMETERS
Each of the functions takes some of the following arguments:
buffer Pointer to the image into which the function is drawing.
x Pointer to array of X coordinates of the points.
y Pointer to array of Y coordinates of the points.
npoints Number of points in the arrays.
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.
