DESCRIPTION

198       Each of the mlib_GraphicsDrawPolyline_*() functions  draws  a  polyline
199       connecting (x1,y1), (x2,y2), ..., and (xn,yn).
200
201
202       Each  of the mlib_GraphicsDrawPolyline_X_*() functions draws a polyline
203       in Xor mode as follows:
204
205             data[x,y] ^= c ^ c2
206
207
208
209       Each of the mlib_GraphicsDrawPolyline_A_*() functions draws a  polyline
210       with antialiasing.
211
212
213       Each  of the mlib_GraphicsDrawPolyline_B_*() functions draws a polyline
214       with alpha blending as follows:
215
216             data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
217
218
219
220       Each of the mlib_GraphicsDrawPolyline_G_*() functions draws a  polyline
221       with Gouraud shading.
222
223
224       Each  of the mlib_GraphicsDrawPolyline_Z_*() functions draws a polyline
225       with Z buffering.
226
227
228       Each of the other functions draws a polyline with a combination of  two
229       or  more  features  like  antialiasing (A), alpha blending (B), Gouraud
230       shading (G), and Z buffering (Z).
231
232
233       Note that the mlib_GraphicsDrawPolyline_*() functions  are  aliases  of
234       the mlib_GraphicsDrawLineStripSet_*() functions.
235

PARAMETERS

237       Each of the functions takes some of the following arguments:
238
239       buffer     Pointer to the image into which the function is drawing.
240
241
242       zbuffer    Pointer to the image that holds the Z buffer.
243
244
245       x          Pointer to array of X coordinates of the points.
246
247
248       y          Pointer to array of Y coordinates of the points.
249
250
251       z          Pointer to array of Z coordinates of the points.
252
253
254       npoints    Number of points in the arrays.
255
256
257       c          Color  used in the drawing, or pointer to array of colors of
258                  the points in the case of Gouraud shading.
259
260
261       c2         Alternation color.
262
263
264       a          Alpha value for blending. 0 ≤ a ≤ 255.
265
266

RETURN VALUES

268       Each of the functions returns MLIB_SUCCESS if successful. Otherwise  it
269       returns MLIB_FAILURE.
