NAME
xfd - font displayer for X
SYNOPSIS
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 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.
