XDrawImageString(3)			  XLIB FUNCTIONS		      XDrawImageString(3)

NAME
       XDrawImageString, XDrawImageString16 - draw image text

SYNTAX
       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);

ARGUMENTS
       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.

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

DESCRIPTION
       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:

       overall-width

       The height is:

       font-ascent + font-descent

       The overall-width, font-ascent, and font-descent are as would be returned by XQueryTextEx-
       tents 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-
       Solid.

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

       Both functions use these GC components: plane-mask, foreground, background, font, subwin-
       dow-mode, clip-x-origin, clip-y-origin, and clip-mask.

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