XFontSetExtents(3X11)

NAME
  XFontSetExtents - XFontSetExtents structure

DESCRIPTION
  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
  characters, of the rectangles that bound the character glyph image drawn in
  the foreground color, relative to a constant origin.	See
  XmbTextExtents(3X11) and XwcTextExtents(3X11) 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
  graphical 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.
