 Name

    xfd - font displayer for X

 Syntax

    xfd [-options ...] -fn fontname

 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 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.


 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 charac-
    ters 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 char-
    acter, 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.

 Known limitations

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