SYNTAX

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

       XDrawImageString16(display, d, gc, x, y, string, length)
             Display *display;
             Drawable d;
             GC gc;
             int x, 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 rela-
                 tive to the origin of the specified drawable and
                 define the origin of the first character.


DESCRIPTION

       The XDrawImageString16 function is similar to XDrawIm-
       ageString 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

       Both functions use these GC components: plane-mask, fore-
       ground, background, font, subwindow-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 cor-
                 rect type and range but fails to match in some
                 other way required by the request.
