XFontSetExtents(3X11)	       XLIB FUNCTIONS		XFontSetExtents(3X11)



NAME
  XFontSetExtents - XFontSetExtents structure

STRUCTURES
  The XFontSetExtents structure contains:

  typedef struct {
       XRectangle max_ink_extent;/* over all drawable characters */
       XRectangle max_logical_extent;/* over all drawable characters */
  } XFontSetExtents;

  The XRectangle structures used to return font set metrics are the usual
  Xlib screen-oriented rectangles with x, y giving the upper left corner, and
  width and height always positive.

  The max_ink_extent member gives the maximum extent, over all drawable char-
  acters, of the rectangles that bound the character glyph image drawn in the
  foreground color, relative to a constant origin.  See XmbTextExtents and
  XwcTextExtents for detailed semantics.

  The max_logical_extent member gives the maximum extent, over all drawable
  characters, of the rectangles that specify minimum spacing to other graphi-
  cal features, relative to a constant origin.	Other graphical features
  drawn by the client, for example, a border surrounding the text, should not
  intersect this rectangle.  The max_logical_extent member should be used to
  compute minimum interline spacing and the minimum area that must be allowed
  in a text field to draw a given number of arbitrary characters.

  Due to context-dependent rendering, appending a given character to a string
  may change the string's extent by an amount other than that character's
  individual extent.
