XFD(1)                      X Version 11(Release 5)                      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, 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 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 background color to be displayed.

      The origin of each glyph is normally set so that the character 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 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 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 displayed 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.
