DESCRIPTION




SunOS 5.11           Last change: 2 Mar 2007                    4






mediaLib Library Functions       mlib_GraphicsDrawPolyline(3MLIB)



     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 combina-
     tion  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.

PARAMETERS
     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.

mediaLib Library Functions       mlib_GraphicsDrawPolyline(3MLIB)



     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 shad-
                ing.


     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.

ATTRIBUTES
     See attributes(5) for descriptions of the  following  attri-
     butes:
