XDrawImageString(3)		XLIB FUNCTIONS		   XDrawImageString(3)

       XDrawImageString, XDrawImageString16 - draw image text

       int XDrawImageString(Display *display, Drawable d, GC gc, int x, int y,
	      char *string, int length);

       int XDrawImageString16(Display *display, Drawable d, GC gc, int x, int
	      y, XChar2b *string, int length);

       d	 Specifies the drawable.

       display	 Specifies the connection to the X server.

       gc	 Specifies the GC.

       length	 Specifies the number of characters in the string argument.

       string	 Specifies the character string.

       y	 Specify the x and y coordinates, which are relative to the
		 origin of the specified drawable and define the origin of the
		 first character.

       The XDrawImageString16 function is similar to XDrawImageString except
       that it uses 2-byte or 16-bit characters.  Both functions also use both
       the foreground and background pixels of the GC in the destination.

       The effect is first to fill a destination rectangle with the background
       pixel defined in the GC and then to paint the text with the foreground
       pixel.  The upper-left corner of the filled rectangle is at:

       [x, y - font-ascent]

       The width is:


       The height is:

       font-ascent + font-descent

       The overall-width, font-ascent, and font-descent are as would be
       returned by XQueryTextExtents using gc and string.  The function and
       fill-style defined in the GC are ignored for these functions.  The
       effective function is GXcopy, and the effective fill-style is Fill‐

       For fonts defined with 2-byte matrix indexing and used with XDrawIm‐
       ageString, each byte is used as a byte2 with a byte1 of zero.

       Both functions use these GC components: plane-mask, foreground, back‐
       ground, font, subwindow-mode, clip-x-origin, clip-y-origin, and clip-

       XDrawImageString and XDrawImageString16 can generate BadDrawable,
       BadGC, and BadMatch errors.

		 A value for a Drawable argument does not name a defined Win‐
		 dow or Pixmap.

       BadGC	 A value for a GContext argument does not name a defined GCon‐

       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
