DESCRIPTION

198       Each of the mlib_GraphicsDrawLineSet_*() functions draws a set of lines
199       connecting  (x1,y1)  with  (x2,y2),  (x3,y3)  with  (x4,y4),  ...,  and
200       (xn-1,yn-1) with (xn,yn).
201
202
203       Each of the mlib_GraphicsDrawLineSet_X_*() functions  draws  a  set  of
204       lines in Xor mode as follows:
205
206             data[x,y] ^= c ^ c2
207
208
209
210       Each  of  the  mlib_GraphicsDrawLineSet_A_*()  functions draws a set of
211       lines with antialiasing.
212
213
214       Each of the mlib_GraphicsDrawLineSet_B_*() functions  draws  a  set  of
215       lines with alpha blending as follows:
216
217             data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
218
219
220
221       Each  of  the  mlib_GraphicsDrawLineSet_G_*()  functions draws a set of
222       lines with Gouraud shading.
223
224
225       Each of the mlib_GraphicsDrawLineSet_Z_*() functions  draws  a  set  of
226       lines with Z buffering.
227
228
229       Each  of the other functions draws a set of lines with a combination of
230       two or more features like antialiasing (A), alpha blending (B), Gouraud
231       shading (G), and Z buffering (Z).
232

PARAMETERS

234       Each of the functions takes some of the following arguments:
235
236       buffer     Pointer to the image into which the function is drawing.
237
238
239       zbuffer    Pointer to the image that holds the Z buffer.
240
241
242       x          Pointer to array of X coordinates of the points.
243
244
245       y          Pointer to array of Y coordinates of the points.
246
247
248       z          Pointer to array of Z coordinates of the points.
249
250
251       npoints    Number  of  points in the arrays. npoints must be a multiple
252                  of 2.
253
254
255       c          Color used in the drawing, or pointer to array of colors  of
256                  the points in the case of Gouraud shading.
257
258
259       c2         Alternation color.
260
261
262       a          Alpha value for blending. 0 ≤ a ≤ 255.
263
264

RETURN VALUES

266       Each  of the functions returns MLIB_SUCCESS if successful. Otherwise it
267       returns MLIB_FAILURE.
