XDrawImageString, XDrawImageString16 \- draw image text
.SH SYNTAX
.HP
int XDrawImageString\^(\^Display *\fIdisplay\fP\^, Drawable \fId\fP\^, GC
\fIgc\fP\^, int \fIx\fP\^, int \fIy\fP\^, char *\fIstring\fP\^, int

.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.
.ds Xy , which are relative to the origin of the specified drawable \
and define the origin of the first character
.IP \fIx\fP 1i
.br
.ns
.IP \fIy\fP 1i
Specify the x and y coordinates\*(Xy.
.SH DESCRIPTION
The
.ZN XDrawImageString16
function is similar to
.ZN 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
.Ds
[x, y \- font-ascent]
.De
.LP
The width is:
.LP
.Ds
overall-width
.De
.LP
The height is:
.LP
.Ds
font-ascent + font-descent
.De
.LP
The overall-width, font-ascent, and font-descent
are as would be returned by 
.ZN XQueryTextExtents 
using gc and string.
The function and fill-style defined in the GC are ignored for these functions. 
The effective function is 
.ZN GXcopy ,
and the effective fill-style is
.ZN FillSolid .
.LP
For fonts defined with 2-byte matrix indexing
and used with
.ZN 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
.ZN XDrawImageString
and
.ZN XDrawImageString16
can generate
.ZN BadDrawable ,
.ZN BadGC ,
and
.ZN BadMatch 
errors.
.SH DIAGNOSTICS
.TP 1i
.ZN BadDrawable
A value for a Drawable argument does not name a defined Window or Pixmap.
.TP 1i
.ZN BadGC
A value for a GContext argument does not name a defined GContext.
.TP 1i
.ZN BadMatch
An
.ZN InputOnly
window is used as a Drawable.
.TP 1i
.ZN 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.
