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, relative to a constant origin.  See
       XmbTextExtents and XwcTextExtents for detailed semantics.

       The max_logical_extent member gives the maximum extent, over all draw-
       able characters, of the rectangles that specify minimum spacing to
       other graphical features, relative to a constant origin.	 Other graph-
       ical 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 num-
       ber 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.
