X Version 11 (Release 5) XDrawImageString(3X11)
NAME
XDrawImageString, XDrawImageString16 - draw image text
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
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-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 correct
type and range but fails to match in some other
way required by the request.
