.TH XFD 1 __xorgversion__
|
|
.SH NAME
|
|
xfd \- display all the characters in an X font
|
|
.SH SYNOPSIS
|
|
.B xfd
|
|
[\-options ...] \fB\-fn\fP \fIfontname\fP
|
|
.PP
|
|
.B xfd
|
|
[\-options ...] \fB\-fa\fP \fIfontname\fP
|
|
.SH DESCRIPTION
|
|
The \fIxfd\fP 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 \fB\-start\fP option has been supplied in which case the
|
|
character with the number given in the \fB\-start\fP option will be used.
|
|
.PP
|
|
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 \fIXlib\fP routine \fBXDrawString16\fP)
|
|
or the XftDrawString32 routine, depending on whether the \fB\-fn\fP or
|
|
\fB\-fa\fP option was given.
|
|
If the \fB\-box\fP option is given, a rectangle will be drawn around each
|
|
character, showing where an ImageText16 request (used by the \fIXlib\fP
|
|
routine \fBXDrawImageString16\fP) would cause background color to be displayed.
|
|
.PP
|
|
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 \fIcursor\fP font), some character may not appear in their
|
|
own grid cells. The \fB\-center\fP option may be used to force all glyphs to
|
|
be centered in their respective cells.
|
|
.PP
|
|
All the characters in the font may not fit in the window at once.
|
|
To see the next page of glyphs, press the \fINext\fP button at the top
|
|
of the window. To see the previous page, press \fIPrev\fP. To exit \fIxfd\fP,
|
|
press \fIQuit\fP.
|
|
.PP
|
|
Individual character metrics (index, width, bearings, ascent and descent) can
|
|
be displayed at the top of the window by clicking on the desired character.
|
|
.PP
|
|
The font name displayed at the top of the window is the full name of the
|
|
font, as determined by the server. See \fIxlsfonts\fP and \fIfc-list\fP
|
|
for ways to generate lists of fonts, as well as more detailed summaries of
|
|
their metrics and properties.
|
|
.SH "OPTIONS"
|
|
.PP
|
|
.I xfd

.TP 8
|
|
.B \-fn \fIfont\fP
|
|
This option specifies the core X server side font to be displayed.
|
|

|
|
the FontGrid \fBfont\fP resource. A font must be specified.
|
|
.TP 8
|
|
.B \-fa \fIfont\fP
|
|

|
|
the FontGrid \fBface\fP resource. A font pattern must be specified.
|
|
.TP 8
|
|
.B \-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 \fBboxChars\fP resource. The default is False.
|
|
.TP 8
|
|
.B \-center
|
|
This option indicates that each glyph should be centered in its grid.
|
|
This can also be set with
|
|
the FontGrid \fBcenterChars\fP resource. The default is False.
|
|
.TP 8
|
|
.B \-start \fInumber\fP
|
|
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 \fBstartChar\fP resource. The default is 0.
|
|
.TP 8
|
|
.B \-bc \fIcolor\fP
|
|
This option specifies the color to be used if ImageText boxes are drawn.
|
|
This can also be set with
|
|
the FontGrid \fBboxColor\fP resource.
|
|
.TP 8
|
|
.B \-rows \fInumrows\fP
|
|
This option specifies the number of rows in the grid.
|
|
This can also be set with
|
|
the FontGrid \fBcellRows\fP resource.
|
|
.TP 8
|
|
.B \-columns \fInumcols\fP
|
|
This option specifies the number of columns in the grid.
|
|
This can also be set with
|
|
the FontGrid \fBcellColumns\fP resource.
|
|
.SH WIDGETS
|
|
In order to specify resources, it is useful to know the
|
|
widgets which compose \fIxfd\fR. In the notation below, indentation
|
|
indicates hierarchical structure. The widget class name is given first,
|
|
followed by the widget instance name.
|
|
The application class name is Xfd.

.SH 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
|
|
instance names of this widget's resources are given in the
|
|
\fBOPTIONS\fP section. Capitalize the first letter of the resource
|
|
instance name to get the corresponding class name.
|
|
.SH APPLICATION SPECIFIC RESOURCES
|
|
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.
|
|
.TP 8
|
|
.B 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.
|
|
.TP 8
|
|
.B 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.
|
|
.TP 8
|
|
.B 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.
|
|
.TP 8
|
|
.B 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.
|
|
.TP 8
|
|
.B 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 \fBselectFormat\fP resource.
