.SH ARGUMENTS
.IP \fId\fP 1i
Specifies the drawable.
.IP \fIdisplay\fP 1i
Specifies the connection to the X server.
.IP \fIgc\fP 1i
Specifies the GC.
.IP \fIlength\fP 1i
Specifies the number of characters in the string argument.
.IP \fIstring\fP 1i
Specifies the character string.
.IP \fIx\fP 1i
.br
.ns
.IP \fIy\fP 1i
Specify the x and y coordinates, which are relative to the
origin of the specified drawable
and define the origin of the first character.
.SH DESCRIPTION
The
.B XDrawImageString16
function is similar to
.B 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.
.LP
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:
.LP
.EX
[x, y \- font-ascent]
.EE
.LP
The width is:
.LP
.EX
overall-width
.EE
.LP
The height is:
.LP
.EX
font-ascent + font-descent
.EE
.LP
The overall-width, font-ascent, and font-descent
are as would be returned by
.B XQueryTextExtents
using gc and string.
The function and fill-style defined in the GC are ignored for these functions.
The effective function is
.BR GXcopy ,
and the effective fill-style is
.BR FillSolid .
.LP
For fonts defined with 2-byte matrix indexing
and used with
.BR XDrawImageString ,
each byte is used as a byte2 with a byte1 of zero.
.LP
Both functions use these GC components:
plane-mask, foreground, background, font, subwindow-mode, clip-x-origin,
clip-y-origin, and clip-mask.
.LP
.B XDrawImageString
and
.B XDrawImageString16
can generate
.BR BadDrawable ,
.BR BadGC ,
and
.B BadMatch
errors.
.SH DIAGNOSTICS
.TP 1i
.B BadDrawable
A value for a Drawable argument does not name a defined Window or Pixmap.
.TP 1i
.B BadGC
A value for a GContext argument does not name a defined GContext.
.TP 1i
.B BadMatch
An
.B InputOnly
window is used as a Drawable.
.TP 1i
.B 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.
