Description
XDrawPoints()
draws multiple points the same way
XDrawPoint() draws one point.
CoordModeOrigin
treats all coordinates as relative to the origin,
and
CoordModePrevious
treats all coordinates after the first as relative to the previous point.
XDrawPoints()
draws the points in the order listed in the array.
This function uses these GC components: function,
plane-mask,
foreground,
subwindow-mode,
clip-x-origin,
clip-y-origin,
and
clip-mask.
XDrawPoints()
can generate
BadDrawable ,
BadGC ,
BadMatch ,
and
BadValue
errors.
Diagnostics
| BadDrawable
| A value for a Drawable argument does not name a
defined Window or Pixmap.
|
| BadGC
| A value for a GContext
argument does not name a defined
GContext.
|
| BadMatch
| An
InputOnly
window is used as a Drawable.
|
| BadMatch
| Some argument or pair of arguments has the correct type and range but fails
to match in some other way required by the request.
|
| BadValue
| Some numeric value falls outside the range of values accepted by the request.
Unless a specific range is specified for an argument, the full range defined
by the argument's type is accepted. Any argument defined as a set of
alternatives can generate this error.
