XFD(1)                                                     XFD(1)


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,  sev-
       eral 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 bot-
       tom.  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 character 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  routine  XDrawImageString16)  would cause back-
       ground color to be displayed.

       The origin of each glyph is normally set so that the char-
       acter  is  drawn in the upper left hand corner of the grid
       cell.  However, if a glyph has a negative left bearing  or
       an  unusually  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  respec-
       tive 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 pressing 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.

       -box    This option indicates that a box  should  be  dis-
               played  outlining  the  area  that would be filled
               with background color by an ImageText request.

       -center This option indicates that each  glyph  should  be
               centered in its grid.

       -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.  The default is 0.

       -bc color
               This option specifies the  color  to  be  used  if
               ImageText boxes are drawn.

X DEFAULTS
       To be written.

       characters.
