mediaLib Library Functions mlibGraphicsDrawPolygon(3MLIB)
DESCRIPTION
Each of the mlibGraphicsDrawPolygon*() functions draws a
polygon enclosing (x1,y1), (x2,y2), ..., and (xn,yn).
Each of the mlibGraphicsDrawPolygonX*() functions draws a
polygon in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlibGraphicsDrawPolygonA*() functions draws a
polygon with antialiasing.
Each of the mlibGraphicsDrawPolygonB*() functions draws a
polygon with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) ] c * a) / 255
Each of the mlibGraphicsDrawPolygonG*() functions draws a
polygon with Gouraud shading.
Each of the mlibGraphicsDrawPolygonZ*() functions draws a
polygon with Z buffering.
Each of the other functions draws a polygon with a combina-
tion of two or more features like antialiasing (A), alpha
blending (B), Gouraud shading (G), and Z buffering (Z).
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 the array of X coordinates of the ver-
tices.
y Pointer to the array of Y coordinates of the ver-
tices.

z Pointer to the array of Z coordinates of the ver-
tices.
npoints Number of vertices 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 MLIBSUCES if successful.
Otherwise it returns MLIBFAILURE.
