XDrawPoint(3X11) XDrawPoint(3X11)NAMEXDrawPoint, XDrawPoints, XPoint - draw points and points structureSYNOPSISXDrawPoint(display, d, gc, x, y) Display *display; Drawable d; GC gc; int x, y; XDrawPoints(display, d, gc, points, npoints, mode) Display *display; Drawable d; GC gc; XPoint *points; int npoints; int mode;ARGUMENTSSpecifies the drawable. Specifies the connection to the X server. Specifies the GC. Specifies the coordinate mode. You can pass Coord- ModeOrigin or CoordModePrevious. Specifies the number of points in the array. Specifies an array of points. Specify the x and y coordi- nates where you want the point drawn.DESCRIPTIONThe XDrawPoint function uses the foreground pixel and function components of the GC to draw a single point into the specified drawable; XDrawPoints draws multiple points this way. 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. Both functions use these GC components: function, plane-mask, foreground, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask. XDrawPoint can generate BadDrawable, BadGC, and BadMatch errors. XDrawPoints can generate BadDrawable, BadGC, BadMatch, and BadValue errors.STRUCTURESThe XPoint structure contains: typedef struct { short x, y; } XPoint; All x and y members are signed integers. The width and height members are 16-bit unsigned integers. You should be careful not to generate coordinates and sizes out of the 16-bit ranges, because the protocol only has 16-bit fields for these values.DIAGNOSTICSA value for a Drawable argument does not name a defined Window or Pixmap. A value for a GContext argument does not name a defined GCon- text. An InputOnly window is used as a Drawable. Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the request. 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 alterna- tives can generate this error.SEE ALSOXDrawArc(3X11), XDrawLine(3X11), XDrawRectangle(3X11) Xlib -- C Language X Interface XDrawPoint(3X11)
