NAME
     xfd - font displayer for X

SYNOPSIS
     xfd [-options ...] -fn _f_o_n_t_n_a_m_e

OPTIONS
     _X_f_d accepts all of the standard toolkit command line options
     along with the additional options listed below:

     -fn _f_o_n_t
             This option specifies the font to be displayed.

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

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

     -start _n_u_m_b_e_r
             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 _c_o_l_o_r
             This option  specifies  the  color  to  be  used  if
             ImageText boxes are drawn.

DESCRIPTION
     The _x_f_d 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  _X_l_i_b  routine  XDrawString16).   If  the -_b_o_x option is
     given, a rectangle will  be  drawn  around  each  character,
     showing  where an ImageText16 request (used by the _X_l_i_b 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 _c_u_r_s_o_r font), some character may not  appear  in  their
     own grid cells.  The -_c_e_n_t_e_r 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 _N_e_x_t button
     at the top of the window.  To see the previous  page,  press
     _P_r_e_v.  To exit _x_f_d, press _Q_u_i_t.

     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 _x_l_s_f_o_n_t_s
     for ways to  generate  lists  of  fonts,  as  well  as  more
     detailed summaries of their metrics and properties.

     The program should skip  over  pages  full  of  non-existent
     characters.
