DESCRIPTION

204       Each of the mlib_GraphicsFillPolygon_*() functions draws a filled poly‐
205       gon enclosing (x1,y1), (x2,y2), ..., and (xn,yn).
206
207
208       Each  of  the  mlib_GraphicsFillPolygon_X_*()  functions draws a filled
209       polygon in Xor mode as follows:
210
211             data[x,y] ^= c ^ c2
212
213
214
215       Each of the mlib_GraphicsFillPolygon_A_*()  functions  draws  a  filled
216       polygon with antialiasing.
217
218
219       Each  of  the  mlib_GraphicsFillPolygon_B_*()  functions draws a filled
220       polygon with alpha blending as follows:
221
222             data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
223
224
225
226       Each of the mlib_GraphicsFillPolygon_G_*()  functions  draws  a  filled
227       polygon with Gouraud shading.
228
229
230       Each  of  the  mlib_GraphicsFillPolygon_Z_*()  functions draws a filled
231       polygon with Z buffering.
232
233
234       Each of the other functions draws a filled polygon with  a  combination
235       of  two  or  more  features  like antialiasing (A), alpha blending (B),
236       Gouraud shading (G), and Z buffering (Z).
237

PARAMETERS

239       Each of the functions takes some of the following arguments:
240
241       buffer     Pointer to the image into which the function is drawing.
242
243
244       zbuffer    Pointer to the image that holds the Z buffer.
245
246
247       x          Pointer to the array of X coordinates of the vertices.
248
249
250       y          Pointer to the array of Y coordinates of the vertices.
251
252
253       z          Pointer to the array of Z coordinates of the vertices.
254
255
256       npoints    Number of vertices in the arrays.
257
258
259       c          Color used in the drawing, or pointer to array of colors  of
260                  the points in the case of Gouraud shading.
261
262
263       c2         Alternation color.
264
265
266       a          Alpha value for blending. 0 ≤ a ≤ 255.
267
268

RETURN VALUES

270       Each  of the functions returns MLIB_SUCCESS if successful. Otherwise it
271       returns MLIB_FAILURE.
