    NAME
         xfd - display all the characters in an X font
    
    SYNOPSIS
         xfd [-options ...] -fn fontname
    
    DESCRIPTION
         The xfd utility creates a window containing the name of  the
         font  being  displayed,  a  row  of command buttons, several
         lines of text for displaying character metrics, and  a  grid
         containing  one glyph per cell.  The characters are shown in
         increasing order from left to right,  top  to  bottom.   The
         first  character displayed at the top left will be character
         number 0 unless the -start option has been supplied in which
         case  the  character  with  the  number  given in the -start
         option will be used.
    
         The characters are displayed in a grid of boxes, each  large
         enough to hold any single character in the font.  Each char-
         acter glyph is drawn using the PolyText16 request  (used  by
         the  Xlib  routine  XDrawString16).   If  the -box option is
         given, a rectangle will  be  drawn  around  each  character,
         showing  where an ImageText16 request (used by the Xlib rou-
         tine XDrawImageString16) would cause background color to  be
         displayed.
    
         The origin of each glyph is normally set so that the charac-
         ter is drawn in the upper left hand corner of the grid cell.
         However, if a glyph has a negative left bearing or an unusu-
         ally large ascent, descent, or right bearing (as is the case
         with cursor font), some character may not  appear  in  their
         own grid cells.  The -center option may be used to force all
         glyphs to be centered in their respective cells.
    
         All the characters in the font may not fit in the window  at
         once.  To see the next page of glyphs, press the Next button
         at the top of the window.  To see the previous  page,  press
         Prev.  To exit xfd, press Quit.
    
         Individual character metrics (index, width, bearings, ascent
         and  descent)  can  be displayed at the top of the window by
         clicking on the desired character.
    
         The font name displayed at the top of the window is the full
         name of the font, as determined by the server.  See xlsfonts
         for ways to  generate  lists  of  fonts,  as  well  as  more
         detailed summaries of their metrics and properties.
    
    OPTIONS
         xfd accepts all of the standard toolkit command line options
         along with the additional options listed below:
    
         -fn font
                 This option specifies  the  font  to  be  displayed.
                 This   can  also  be  set  with  the  FontGrid  font
                 resource.  A font must be specified.
    
         -box    This option indicates that a box should be displayed
                 outlining  the  area that would be filled with back-
                 ground color by an ImageText request.  This can also
                 be  set  with  the  FontGrid boxChars resource.  The
                 default is False.
    
         -center This option indicates that each glyph should be cen-
                 tered  in  its  grid.  This can also be set with the
                 FontGrid  centerChars  resource.   The  default   is
                 False.
    
         -start number
                 This option specifies the glyph index of  the  upper
                 left  hand corner of the grid.  This is used to view
                 characters at arbitrary locations in the font.  This
                 can   also   be  set  with  the  FontGrid  startChar
                 resource.  The default is 0.
    
         -bc color
                 This option  specifies  the  color  to  be  used  if
                 ImageText  boxes  are  drawn.   This can also be set
                 with the FontGrid boxColor resource.
    
         -rows numrows
                 This option specifies the  number  of  rows  in  the
                 grid.   This  can  also  be  set  with  the FontGrid
                 cellRows resource.
    
         -columns numcols
                 This option specifies the number of columns  in  the
                 grid.   This  can  also  be  set  with  the FontGrid
                 cellColumns resource.
    
    WIDGETS
         In order to specify resources, it  is  useful  to  know  the
         widgets  which compose xfd.  In the notation below, indenta-
         tion indicates hierarchical  structure.   The  widget  class
         name  is  given first, followed by the widget instance name.
         The application class name is Xfd.

    FONTGRID RESOURCES
         The FontGrid widget is an application-specific widget, and a
         subclass of the Simple widget in the Athena widget set.  The
         effects and instance names of this  widget's  resources  are
         given  in  the OPTIONS section.  Capitalize the first letter
         of the resource instance name to get the corresponding class
         name.
    
    APPLICATION SPECIFIC RESOURCES
         The instance names of the application specific resources are
         given  below.   Capitalize  the first letter of the resource
         instance name to get the corresponding  class  name.   These
         resources  are  unlikely  to  be  interesting unless you are
         localizing xfd for a different language.
    
         selectFormat
                 Specifies  a  printf-style  format  string  used  to
                 display  information  about  the selected character.
                 The  default  is   "character   0x%02x%02x   (%u,%u)
                 (%#o,%#o)".   The arguments that will come after the
                 format   string    are    char.byte1,    char.byte2,
                 char.byte1,   char.byte2,   char.byte1,  char.byte2.
                 char.byte1 is byte  1  of  the  selected  character.
                 char.byte2 is byte 2 of the selected character.
    
         metricsFormat
                 Specifies  a  printf-style  format  string  used  to
                 display  character  metrics.   The default is "width
                 %d; left %d, right %d; ascent %d, descent  %d  (font
                 %d,  %d)".   The  arguments that will come after the
                 format  string  are  the  character  metrics  width,
                 lbearing, rbearing, character ascent, character des-
                 cent, font ascent, and font descent.
    
         rangeFormat
                 Specifies  a  printf-style  format  string  used  to
                 display  the  range  of  characters  currently being
                 displayed.   The  default  is  "range:    0x%02x%02x
                 (%u,%u)  thru  0x%02x%02x  (%u,%u)".   The arguments
                 that will come after the format string are the  fol-
                 lowing  fields from the XFontStruct that is returned
                 from     opening     the      font:       min_byte1,
                 min_char_or_byte2,   min_byte1,   min_char_or_byte2,
                 max_byte1,       max_char_or_byte2,       max_byte1,
                 max_char_or_byte2.
    
         startFormat
                 Specifies  a  printf-style  format  string  used  to
                 display information about the character at the upper
                 left corner of the font grid.  The default is "upper
                 left: 0x%04x (%d,%d)".  The arguments that will come
                 after the format string are the new  character,  the
                 high  byte of the new character, and the low byte of
                 the new character.
    
         nocharFormat
                 Specifies a printf-style format  string  to  display
                 when  the  selected  character  does not exist.  The
                 default is "no  such  character  0x%02x%02x  (%u,%u)
                 (%#o,%#o)".   The arguments that will come after the
                 format string are the same as for  the  selectFormat
                 resource.
