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 specified 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 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 FillSolid.

       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, subwindow-mode, clip-x-ori-
       gin, 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.
