XDrawRectangle(3X11)        X Version 11(Release 5)        XDrawRectangle(3X11)


NAME
      XDrawRectangle, XDrawRectangles, XRectangle - draw rectangles and
      rectangles structure

SYNTAX
      XDrawRectangle(display, d, gc, x, y, width, height)
            Display *display;
            Drawable d;
            GC gc;
            int x, y;
            unsigned int width, height;

      XDrawRectangles(display, d, gc, rectangles, nrectangles)
            Display *display;
            Drawable d;
            GC gc;
            XRectangle rectangles[];
            int nrectangles;

ARGUMENTS
      d         Specifies the drawable.

      display   Specifies the connection to the X server.

      gc        Specifies the GC.

      nrectangles
                Specifies the number of rectangles in the array.

      rectangles
                Specifies an array of rectangles.

      width
      height    Specify the width and height, which specify the dimensions of
                the rectangle.

      x
      y         Specify the x and y coordinates, which specify the upper-left
                corner of the rectangle.

DESCRIPTION
      The XDrawRectangle and XDrawRectangles functions draw the outlines of the
      specified rectangle or rectangles as if a five-point PolyLine protocol
      request were specified for each rectangle:

            [x,y] [x+width,y] [x+width,y+height] [x,y+height] [x,y]

      For the specified rectangle or rectangles, these functions do not draw a
      pixel more than once.  XDrawRectangles draws the rectangles in the order
      listed in the array.  If rectangles intersect, the intersecting pixels
      are drawn multiple times.

      Both functions use these GC components: function, plane-mask, line-width,
      line-style, cap-style, join-style, fill-style, subwindow-mode, clip-x-
      origin, clip-y-origin, and clip-mask.  They also use these GC mode-
      dependent components: foreground, background, tile, stipple, tile-
      stipple-x-origin, tile-stipple-y-origin, dash-offset, and dash-list.

      XDrawRectangle and XDrawRectangles can generate BadDrawable, BadGC, and
      BadMatch errors.

STRUCTURES
      The XRectangle structure contains:

      typedef struct {
           short x, y;
           unsigned short width, height;
      } XRectangle;

      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.

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.
