XFD(1)			    General Commands Manual			XFD(1)

NAME
       xfd - display all the characters	in an X	font

SYNOPSIS
       xfd [-options ...] -fn fontname

       xfd [-options ...] -fa 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 display-
       ing  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 charac-
       ter 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)
       or the XftDrawString32 routine, depending on whether the	-fn or -fa op-
       tion was	given.	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  de-
       scent) can be displayed at the top of the window	by clicking on the de-
       sired 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 and fc-list for
       ways to generate	lists of fonts,	as well	as more	detailed summaries  of
       their metrics and properties.

OPTIONS
       xfd accepts all of the standard toolkit command line options along with
       the additional options listed below:

       -fn font
	       This option specifies the core X	server side font  to  be  dis-
	       played.	 This can also be set with the FontGrid	font resource.
	       A font must be specified.

       -fa font
	       This option specifies a Xft font	to be displayed. This can also
	       be  set with the	FontGrid face resource.	A font pattern 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 Im-
	       ageText request.	 This can also be set with the	FontGrid  box-
	       Chars 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  re-
	       source.	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	 arbi-
	       trary  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 re-
	       source.

       -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 cellColumns resource.

WIDGETS
       In order	to specify resources, it is useful to know the	widgets	 which
       compose xfd.  In	the notation below, indentation	indicates hierarchical
       structure.  The widget class name is given first, followed by the  wid-
       get instance name.  The application class name is Xfd.

		      Command  prev

FONTGRID RESOURCES
       The  FontGrid  widget is	an application-specific	widget,	and a subclass
       of the Simple widget in the Athena widget set.	The  effects  and  in-
       stance  names  of this widget's resources are given in the OPTIONS sec-
       tion.  Capitalize the first letter of the resource instance name	to get
       the corresponding class name.

APPLICATION SPECIFIC RESOURCES
       The  instance names of the application specific resources are given be-
       low.  Capitalize	the first letter of the	resource instance name to  get
       the  corresponding  class name.	These resources	are unlikely to	be in-
       teresting unless	you are	localizing xfd for a different language.

       selectFormat
	       Specifies a printf-style	format string used to display informa-
	       tion  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  charac-
	       ter  metrics.  The default is "width %d;	left %d, right %d; as-
	       cent %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 argu-
	       ments 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 informa-
	       tion  about  the	character at the upper left corner of the font
	       grid.  The default is "upper left: 0x%04x (%d,%d)".  The	 argu-
	       ments  that will	come after the format string are the new char-
	       acter, 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 se-
	       lected character	does not exist.	 The default is	"no such char-
	       acter  0x%02x%02x  (%u,%u) (%#o,%#o)".  The arguments that will
	       come after the format string are	the same as for	the selectFor-
	       mat resource.

BUGS
       The program should skip over pages full of non-existent characters.
