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 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.
