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 characters, of the rectangles that bound the
       character glyph image drawn in the foreground color, rela
       tive to a constant origin.  See XmbTextExtents and XwcTex_
       tExtents for detailed semantics.

       The max_logical_extent member gives the maximum extent,
       over all drawable characters, of the rectangles that spec
       ify 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 mini
       mum interline spacing and the minimum area that must be
       allowed in a text field to draw a given number of arbi
       trary 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.
