XwcTextExtents()														  XwcTextExtents()

Name
  XwcTextExtents - compute the extents of internationalized wide-character text.

Synopsis
  int XwcTextExtents(font_set, string, num_wchars, overall_ink_return,
  overall_logical_return)
	XFontSet font_set;
	wchar_t *string;
	int num_wchars;
	XRectangle *overall_ink_return;
	XRectangle *overall_logical_return;

Arguments
  font_set  Specifies the font set.

  string    Specifies the character string.

  num_wchars
	    Specifies the number of characters in the string argument.

  overall_ink_return
	    Returns the overall ink dimensions.

  overall_logical_return
	    Returns the overall logical dimensions.

Returns
  The escapement in pixels.

Availability
  Release 5 and later.

Description
  XwcTextExtents()  sets  the components of the specified overall_ink_return and overall_logical_return arguments to the overall bounding box
  of the string's image, and the overall logical bounding box of the string's image plus inter-line and inter-character spacing.  It  returns
  the  value  returned by XwcTextEscapement().	The returned metrics are relative to the drawing origin of the string, using the fonts loaded
  for the specified font set.

  If the overall_ink_return argument is  non-NULL,  it	is  set  to  the  bounding  box  of  the  string's  character  ink.   Note  that  the
  overall_ink_return   for   a	 non-descending   horizontally	 drawn	Latin  character  is  conventionally  entirely	above  the  baseline,
  that is, overall_ink_return.height <= -overall_ink_return.y.	The overall_ink_return for a nonkerned character is entirely at  and  to  the
  right  of  the  origin,  that  is,  overall_ink_return.x  >=	0.   A	character  consisting  of  a  single  pixel  at the origin would have
  overall_ink_return fields y = 0, x = 0, width = 1, and height = 1.

  If the overall_logical_return argument is non-NULL, it is set to the bounding box which provides minimum spacing to  other  graphical  fea-
  tures for the string.  Other graphical features, for example, a border surrounding the text, should not intersect this rectangle.

  When	the  XFontSet  has  missing  charsets,	metrics for each unavailable character are taken from the default string returned by XCreate-
  FontSet() so that the metrics represent the text as it will actually be drawn.  The behavior for an invalid codepoint is undefined.

Structures
     typedef struct {
	 short x, y;
	 unsigned short width, height;
     } XRectangle;
