Each of the mlib_GraphicsDrawPolyline_*() functions draws a polyline connecting (x1,y1), (x2,y2), ..., and (xn,yn). Each of the mlib_GraphicsDrawPolyline_X_*() functions draws a polyline in Xor mode as follows: data[x,y] ^= c ^ c2 Each of the mlib_GraphicsDrawPolyline_A_*() functions draws a polyline with antialiasing. Each of the mlib_GraphicsDrawPolyline_B_*() functions draws a polyline with alpha blending as follows: data[x,y] = (data[x,y] * (255 - a) + c * a) / 255 Each of the mlib_GraphicsDrawPolyline_G_*() functions draws a polyline with Gouraud shading. Each of the mlib_GraphicsDrawPolyline_Z_*() functions draws a polyline with Z buffering. Each of the other functions draws a polyline with a combination of two or more features like antialiasing (A), alpha blending (B), Gouraud shading (G), and Z buffering (Z). Note that the mlib_GraphicsDrawPolyline_*() functions are aliases of the mlib_GraphicsDrawLineStripSet_*() functions. Each of the functions takes some of the following arguments: buffer Pointer to the image into which the function is drawing. zbuffer Pointer to the image that holds the Z buffer. x Pointer to array of X coordinates of the points. y Pointer to array of Y coordinates of the points. z Pointer to array of Z coordinates of the points. npoints Number of points in the arrays. c Color used in the drawing, or pointer to array of colors of the points in the case of Gouraud shading. c2 Alternation color. a Alpha value for blending. 0 <= a <= 255. Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
