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 XWIN 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 rela-
          tive to the origin of the specified drawable and
          define the origin of the first character.

DESCRIPTION

The XDrawImageString16 function is similar to XDrawImage-
String 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:

XWIN 3.0               Last change: 9/1/88                 .ie t

     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 Bad-
Drawable, 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.
