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.
