xfd(1) X Version 11 (25 October 1988) xfd(1)
NAME
xfd - displays fonts for X
SYNOPSIS
xfd [-options ...] -fn fontname
DESCRIPTION
The xfd program opens a window and displays the characters
in the font you specify with the -fn argument. The
characters are shown in increasing order from left to right,
top to bottom. The first character displayed at the top
left is character number 0 unless you specify a different
character number with the -start option.
The characters are displayed in a grid of boxes, each large
enough to hold any single character in the font. If you
specify the -gray option, the characters are displayed using
XDrawImageString using the foreground and background colors
on a gray background. This allows xfd to determine exactly
how XDrawImageString draws any given character. If you do
not specify -gray, xfd draws the characters using the
foreground color on the background color.
All characters in a given font may not fit in the window at
once. To see additional characters, click the right mouse
button on the window. This causes the next window of
characters to be displayed. Clicking the left mouse button
on the window causes the previous window of characters to be
displayed. If you make an attempt to go back past the 0th
character, xfd beeps.
Note that if the font is an eight-bit font, the characters
256-511 (100-1ff in hexidecimal), 512-767 (200-2ff in
hexidecimal), and so on, display exactly the same as the
characters 0-255 (00-ff in hexidecimal). By default, xfd
creates a window big enough to display 16 rows of 16 columns
(totalling 256 characters).
Clicking the middle button on a character displays that
character's number in both decimal and hexidecimal at the
bottom of the window.
If you select verbose (-verbose) mode, additional
information about that particular character is displayed as
well. The displayed information includes the width of the
character, its left bearing, right bearing, ascent, and
descent. In verbose mode, you can also type < or > anywhere
in the window to display the minimum or maximum values of
the font's left bearing, right bearing, ascent, and descent.
The font name is interpreted by the X server. To obtain a
list of all the fonts available, use xlsfonts(1).
