DESCRIPTION
Xfd creates a window in which the characters in the named font are
displayed. 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. If the -gray option has been
supplied, the characters will be displayed using XDrawImageString using
the foreground and background colors on a gray background. This permits
determining exactly how XDrawImageString will draw any given character.
If -gray has not been supplied, the characters will simply be drawn using
the foreground color on the background color.
All the characters in the font may not fit in the window at once. To see
additional characters, click the right mouse button on the window. This
will cause the next window full of characters to be displayed. Clicking
the left mouse button on the window will cause the previous window full
of characters to be displayed. Xfd will beep if an attempt is made to go
back past the 0th character.
Note that if the font is a 8 bit font, the characters 256-511 (100-1ff in
hexidecimal), 512-767 (200-2ff in hexidecimal), ... will display exactly
the same as the characters 0-255 (00-ff in hexidecimal). Xfd by default
creates a window big enough to display 16 rows of 16 columns (totally 256
characters).
Clicking the middle button on a character will cause that character's
number to be displayed in both decimal and hexidecimal at the bottom of
the window. If verbose mode is selected, additional information about
that particular character will be displayed as well. The displayed
information includes the width of the character, its left bearing, right
bearing, ascent, and its descent. If verbose mode is selected, typing
'<' or '>' into the window will display the minimum or maximum values
respectively taken on by each of these fields over the entire font.
The font name is interpreted by the X server. To obtain a list of all
the fonts available, use xlsfonts(1).
The window stays around until the xfd process is killed or one of 'q',
'Q', ' ', or ctrl-c is typed into the Xfd window.
X DEFAULTS
Xfd uses the following X resources:
BorderWidth Set the border width of the window.
BorderColor Set the border color of the window.
ReverseVideo If ``on'', reverse the definition of foreground and
background color.
Foreground Set the foreground color.
Background Set the background color.
BodyFont Set the font to be used in the body of the window. (I.e.,
for messages, etc.) This is not the font that Xfd displays,
just the font it uses to display information about the font
being displayed.
IconName Set the name of the icon.
IconBitmap Set the file we should look in to get the bitmap for the
icon.
Title Set the title to be used.

BUGS
It should display the name of the font somewhere.
Character information displayed in verbose mode is sometimes clipped to
the window boundary, hiding it from view.
It should be rewritten to use the X toolkit.
It should skip over pages full of non-existent characters.
