DESCRIPTION

199       Each  of  the  mlib_GraphicsDrawLine_*() functions draws a line between
200       (x1,y1) and (x2,y2).
201
202
203       Each of the mlib_GraphicsDrawLine_X_*() functions draws a line  between
204       (x1,y1) and (x2,y2) in Xor mode as follows:
205
206             data[x,y] ^= c ^ c2
207
208
209
210       Each  of the mlib_GraphicsDrawLine_A_*() functions draws a line between
211       (x1,y1) and (x2,y2) with antialiasing.
212
213
214       Each of the mlib_GraphicsDrawLine_B_*() functions draws a line  between
215       (x1,y1) and (x2,y2) 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_GraphicsDrawLine_G_*() functions draws a line between
222       (x1,y1) and (x2,y2) with Gouraud shading.
223
224
225       Each of the mlib_GraphicsDrawLine_Z_*() functions draws a line  between
226       (x1,y1) and (x2,y2) with Z buffering.
227
228
229       Each  of  the  other functions draws a line between (x1,y1) and (x2,y2)
230       with a combination of two or more features like antialiasing (A), alpha
231       blending (B), Gouraud 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       x1         X coordinate of the first point.
243
244
245       y1         Y coordinate of the first point.
246
247
248       z1         Z coordinate of the first point.
249
250
251       x2         X coordinate of the second point.
252
253
254       y2         Y coordinate of the second point.
255
256
257       z2         Z coordinate of the second point.
258
259
260       c          Color used in the drawing.
261
262
263       c1         Color of the first point.
264
265
266       c2         Color  of  the second point, or the alternation color in the
267                  Xor mode.
268
269
270       a          Alpha value for blending. 0 ≤ a ≤ 255.
271
272

RETURN VALUES

274       Each of the functions returns MLIB_SUCCESS if successful. Otherwise  it
275       returns MLIB_FAILURE.
