XDrawText(3X11)		XLIB FUNCTIONS	  XDrawText(3X11)

NAME
       XDrawText, XDrawText16, XTextItem, XTextItem16 - draw
       polytext text and text drawing structures

SYNTAX
       XDrawText(display, d, gc, x, y, items, nitems)
	     Display *display;
	     Drawable d;
	     GC gc;
	     int x, y;
	     XTextItem *items;
	     int nitems;

       XDrawText16(display, d, gc, x, y, items, nitems)
	     Display *display;
	     Drawable d;
	     GC gc;
	     int x, y;
	     XTextItem16 *items;
	     int nitems;

ARGUMENTS
       d	 Specifies the drawable.

       display	Specifies the connection to the X server.

       gc	Specifies the GC.

       items	Specifies an array of text items.

       nitems	Specifies the number of text items in the array.

       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 XDrawText16 function is similar to XDrawText except
       that it uses 2-byte or 16-bit characters.  Both functions
       allow complex spacing and font shifts between counted
       strings.

       Each text item is processed in turn.  A font member other
       than None in an item causes the font to be stored in the
       GC and used for subsequent text. A text element delta
       specifies an additional change in the position along the x
       axis before the string is drawn. The delta is always
       added to the character origin and is not dependent on any
       characteristics of the font.  Each character image, as
       defined by the font in the GC, is treated as an additional
       mask for a fill operation on the drawable.  The drawable
       is modified only where the font character has a bit set to
       1.  If a text item generates a BadFont error, the previous

       text items may have been drawn.

       For fonts defined with linear indexing rather than 2-byte
       matrix indexing, each XChar2b structure is interpreted as
       a 16-bit number with byte1 as the most significant byte.

       Both functions use these GC components: function, plane-
       mask, fill-style, font, 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, and tile-stipple-y-origin.

       XDrawText and XDrawText16 can generate BadDrawable,
       BadFont, BadGC, and BadMatch errors.

STRUCTURES
       The XTextItem and XTextItem16 structures contain:

       typedef struct {
	    char *chars;	     /* pointer to string */
	    int nchars;		/* number of characters */
	    int delta;		/* delta between strings */
	    Font font;		/* Font to print it in, None don't change */
       } XTextItem;

       typedef struct {
	    XChar2b *chars;	  /* pointer to two-byte characters */
	    int nchars;		/* number of characters */
	    int delta;		/* delta between strings */
	    Font font;		/* font to print it in, None don't change */
       } XTextItem16;

       If the font member is not None, the font is changed before
       printing and also is stored in the GC.  If an error was
       generated during text drawing, the previous items may have
       been drawn.  The baseline of the characters are drawn
       starting at the x and y coordinates that you pass in the
       text drawing functions.

       For example, consider the background rectangle drawn by
       XDrawImageString.  If you want the upper-left corner of
       the background rectangle to be at pixel coordinate (x,y),
       pass the (x,y + ascent) as the baseline origin coordinates
       to the text functions.  The ascent is the font ascent, as
       given in the XFontStruct structure.  If you want the
       lower-left corner of the background rectangle to be at
       pixel coordinate (x,y), pass the (x,y - descent + 1) as
       the baseline origin coordinates to the text functions.
       The descent is the font descent, as given in the
       XFontStruct structure.

DIAGNOSTICS
       BadDrawable
		 A value for a Drawable argument does not name a

		 defined Window or Pixmap.

       BadFont	A value for a Font or GContext argument does not
		 name a defined Font.

       BadGC	A value for a GContext argument does not name a
		 defined GContext.

       BadMatch An InputOnly window is used as a Drawable.
