157 Specifies the drawable.
159 Specifies the connection to the X server.
163 Specifies the coordinate mode.
167 .ZN CoordModePrevious .
169 Specifies the number of points in the array.
170 .IP \fInsegments\fP 1i
171 Specifies the number of segments in the array.
173 Specifies an array of points.
174 .IP \fIsegments\fP 1i
175 Specifies an array of segments.
186 Specify the points (x1, y1) and (x2, y2) to be connected.
190 function uses the components of the specified GC to
191 draw a line between the specified set of points (x1, y1) and (x2, y2).
192 It does not perform joining at coincident endpoints.
195 does not draw a pixel more than once.
196 If lines intersect, the intersecting pixels are drawn multiple times.
200 function uses the components of the specified GC to draw
201 npoints\-1 lines between each pair of points (point[i], point[i+1])
205 It draws the lines in the order listed in the array.
206 The lines join correctly at all intermediate points, and if the first and last
207 points coincide, the first and last lines also join correctly.
210 does not draw a pixel more than once.
211 If thin (zero line-width) lines intersect,
212 the intersecting pixels are drawn multiple times.
213 If wide lines intersect, the intersecting pixels are drawn only once, as though
216 protocol request were a single, filled shape.
218 treats all coordinates as relative to the origin,
220 .ZN CoordModePrevious
221 treats all coordinates after the first as relative to the previous point.
225 function draws multiple, unconnected lines.
229 line between (x1, y1) and (x2, y2).
230 It draws the lines in the order listed in the array of
232 structures and does not perform joining at coincident endpoints.
235 does not draw a pixel more than once.
236 If lines intersect, the intersecting pixels are drawn multiple times.
238 All three functions use these GC components:
239 function, plane-mask, line-width,
240 line-style, cap-style, fill-style, subwindow-mode,
241 clip-x-origin, clip-y-origin, and clip-mask.
244 function also uses the join-style GC component.
245 All three functions also use these GC mode-dependent components:
246 foreground, background, tile, stipple, tile-stipple-x-origin,
247 tile-stipple-y-origin, dash-offset, and dash-list.
272 short x1, y1, x2, y2;
276 All x and y members are signed integers.
277 The width and height members are 16-bit unsigned integers.
278 You should be careful not to generate coordinates and sizes
279 out of the 16-bit ranges, because the protocol only has 16-bit fields
284 A value for a Drawable argument does not name a defined Window or Pixmap.
287 A value for a GContext argument does not name a defined GContext.
292 window is used as a Drawable.
295 Some argument or pair of arguments has the correct type and range but fails
296 to match in some other way required by the request.
299 Some numeric value falls outside the range of values accepted by the request.
300 Unless a specific range is specified for an argument, the full range defined
301 by the argument's type is accepted. Any argument defined as a set of
302 alternatives can generate this error.
