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 PolyTextl6 request (used by
the Xlib routine XDrawString16). If the - box option is given, a
rectangle will be drawn around each character, showing where an ImageTextl6 request (used
by the Xlib routine XDrawImageStringl6) 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 clicking 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.
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. This can also be set with the FontGrid
font resource. A font must be specified.
- box
This option indicates that a box should be displayed outlining the area that would be
filled with background color by an ImageText request. This can also be set with the
FontGrid boxChars resource. The default is False.
- center
This option indicates that each glyph should be centered in its grid. This can also be
set with the FontGrid centerChars resource. The default is False.
- 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. This can also be set with the
FontGrid startChar resource. The default is 0.
- bc color
This option specifies the color to be used if ImageText boxes are drawn. This can also
be set with the FontGrid boxColor resource.
- rows numrows
This option specifies the number of rows in the grid. This can also be set with the
FontGrid cellRows resource.
- columns numcols
This option specifies the number of columns in the grid. This can also be set with the
FontGrid cellColumnsresource.
The instance names of the application specific resources are given below. Capitalize
the first letter of the resource instance name to get the corresponding class name. These
resources are unlikely to be interesting unless you are localizing xfd for a different
language.
selectFormat
Specifies a printf-style format string used to display information about the selected
character.
The default is "character 0x%02x%02x (%u,%u) (%# o,%# o)". The arguments that
will come after the format string are char.byte1, char.byte2, char.byte1, char.byte2,
char.byte1, char.byte2. char.byte1 is byte 1 of the selected character. char.byte2 is byte
2 of the selected character.
metricsFormat
Specifies a printf-style format string used to display character metrics. The default is
"width %d; left %d, right %d; ascent %d, descent %d (font %d, %d)". The
arguments that will come after the format string are the character metrics width,
lbearing, rbearing, character ascent, character descent, font ascent, and font descent.
rangeFormat
Specifies a printf-style format string used to display the range of characters currently
being displayed. The default is "range: 0x%02x%02x (%u,%u) thru 0x%02x%02x
(%u,%u)". The arguments that will come after the format string are the following
fields from the XFontStruct that is returned from opening the font: min_byte1,
min_char_or_byte2, min_byte1, min_char_or_byte2, max_byte1, max_char_or_byte2, max_byte1,
max_char_or_byte2.
startFormat
Specifies a printf-style format string used to display information about the character
at the upper left corner of the font grid. The default is "upper left: 0x%04x
(%d,%d)". The arguments that will come after the format string are the new character,
the high byte of the new character, and the low byte of the new character.
nocharFormat
Specifies a printf-style format string to display when the selected character does not
exist. The default is "no such character 0x%02x%02x (%u,%u) (%#o,%#o)". The
arguments that will come after the format string are the same as for the selectFormat resource.
- NAME
-
xfontset - point & click interface for selecting X11 font names
- SYNOPSIS
- xfontsel [-toolkitoption ...] [-pattern fontname] [-print]
[-sample text] [-samplel1 text16] [ noscaled]
- DESCRIPTION
-
The xfontsel application provides a simple way to display the fonts known to your
X server, examine samples of each, and retrieve the X Logical Font Description
("XLFD") full name for a font.
If -pattern is not specified, all fonts with XLFD 14-part names will be selectable.
To work with only a subset of the fonts, specify -pattern followed by a partially
or fully qualified font name; e.g., "-pattern *medium*" will select that subset
of fonts which contain the string "medium" somewhere in their font name. Be
careful about escaping wildcard characters in your shell.
If -print is specified on the command line the selected font specifier will be
written to standard output when the quit button is activated. Regardless of whether
or not -print was specified, the font specifier may be made the PRIMARY (text)
selection by activating the select button.
The -sample option specifies the sample text to be used to display the selected
font if the font is linearly indexed, overriding the default.
The -sample16 option specifies the sample text to be used to display the selected
font if the font is matrix encoded, overriding the default.
The -noscaled option disables the ability to select scaled fonts at arbitrary pixel
or point sizes. This makes it clear which bitmap sizes are advertised by the server, and
can avoid an accidental and sometimes prolonged wait for a font to be scaled.
- INTERACTIONS
-
Clicking any pointer button in one of the XLFD field names will pop up a menu of the
currently-known possibilities for that field. If previous choices of other fields were
made, only values for fonts which matched the previously selected fields will be
selectable; to make other values selectable, you must deselect some other field(s) by
choosing the "*" entry in that field. Unselectable values may be omitted from
the menu entirely as a configuration option; see the ShowUnselectable resource,
below. Whenever any change is made to a field value, xfontsel will assert ownership
of the PRIMARY_FONT selection. Other applications (see, e.g., xterm) may then
retrieve the selected font specification.
Scalable fonts come back from the server with zero for the pixel size, point size, and
average width fields. Selecting a font name with a zero in these positions results in an
implementation-dependent size. Any pixel or point size can be selected to scale the font
to a particular size. Any average width can be selected to anamorphically scale the font
(although you may find this challenging given the size of the average width menu).
Clicking the left pointer button in the select widget will cause the currently
selected font name to become the PRIMARY text selection as well as the PRIMARY_FONT
selection. This then allows you to paste the string into other applications. The select
button remains highlighted to remind you of this fact, and de-highlights when some other
application takes the PRIMARY selection away. The select widget is a toggle;
pressing it when it is highlighted will cause xfontsel to release the selection
ownership and de-highlight the widget. Activating the select widget twice is the
only way to cause xfontsel to release the PRIMARY_FONT selection.
- RESOURCES
-
The application class is XFontSel. Most of the user-interface is configured in
the app-defaults file; if this file is missing a warning message will be printed to
standard output and the resulting window will be nearly incomprehensible.
Most of the significant parts of the widget hierarchy are documented in the app-defaults
file (normally < Xrooto> /lib/X11/app-defaults/XFontSel, where < XRoot> refers
to the root of the X11 install tree.)
Application specific resources:
cursor (class Cursor)
Specifies the cursor for the application window.
pattern (class Pattern)
Specifies the font name pattern for selecting a subset of available fonts. Equivalent to
the pattern option. Most useful patterns will contain at least one field delimiter;
e.g. *-m-* for monospaced fonts.
plxelSizeList (class PixelSizeList)
Specifies a list of pixel sizes to add to the pixel size menu, so that scalable fonts
can be selected at those pixel sizes. The default pixelSizeList contains 7, 30, 40, 50,
and 60.
pointSizeList (class PointSizeList)
Specifies a list of point sizes (in units of tenths of points) to add to the point size
menu, so that scalable fonts can be selected at those point sizes. The default
pointSizeList contains 250, 300, 350, and 400.
printOnQuit (class PrintOnQuit)
If True the currently selected font name is printed to standard output when the
quit button is activated. Equivalent to the -print option.
sampleText (class Text)
The sample 1-byte text to use for linearly indexed fonts. Each glyph index is a single
byte, with newline separating lines.
sampleTextl6 (class Textl6)
The sample 2-byte text to use for matrix-encoded fonts. Each glyph index is two bytes,
with a 1-byte newline separating lines.
scaledFons (class ScaledFonts)
If True then selection of arbitrary pixel and point sizes for scalable fonts is
enabled.
Widget specific resources:
showUnselectable (class ShowUnselectable)
Specifies, for each field menu, whether or not to show values that are not currently
selectable, based upon previous field selections. If shown, the unselectable values are
clearly identified as such and do not highlight when the pointer is moved down the menu.
The full name of this resource is fleldN.menu.options.showUnselectable, class MenuButton.SimpleMenu.Options.ShowUnselectable;
where N is replaced with the field number (starting with the left-most field numbered 0).
The default is True for all but field 11 (average width of characters in font) and False
for field 11. If you never want to see unselectable entries,
'*menu.options.showUnselectable:False' is a reasonable thing to specify in a resource
file.

- BUGS
-
Sufficiently ambiguous patterns can be misinterpreted and lead to an initial selection
string which may not correspond to what the user intended and which may cause the initial
sample text output to fail to match the proffered string. Selecting any new field value
will correct the sample output, though possibly resulting in no matching font.
Should be able to return a FONT for the PRIMARY selection, not just a STRING.
Any change in a field value will cause xfontsel to assert ownership of the
PRIMARY_FONT selection. Perhaps this should be parameterized.
When running on a slow machine, it is possible for the user to request a field menu before
the font names have been completely parsed. An error message indicating a missing menu is
printed to stderr but otherwise nothing bad (or good) happens.
The average-width menu is too large to be useful.
