XFD(1X11) COMMAND REFERENCE XFD(1X11) NAME xfd - font displayer for X SYNOPSIS xfd [-options ...] -fn fontname This is a user-contributed client. DESCRIPTION The xfd font displayer creates a window in which the characters in the named font are displayed. 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. If the - gray option has been supplied, the characters will be displayed using XDrawImageString using the foreground and background colors on a gray background. This permits determining exactly how XDrawImageString will draw any given character. If -gray has not been supplied, the characters will simply be drawn using the foreground color on the background color. All the characters in the font may not fit in the window at once. To see additional characters, click the right mouse button on the window. This will cause the next window full of characters to be displayed. Clicking the left mouse button on the window will cause the previous window full of characters to be displayed; xfd will beep if an attempt is made to go back past the 0th character. Note that if the font is an 8 bit font, the characters 256- 511 (100-1ff in hexidecimal), 512-767 (200-2ff in hexidecimal), ... will display exactly the same as the characters 0-255 (00-ff in hexidecimal). By default xfd creates a window big enough to display 16 rows of 16 columns (totally 256 characters). Clicking the middle button on a character will cause that character's number to be displayed in both decimal and hexidecimal at the bottom of the window. If verbose mode is selected, additional information about that particular character will be displayed as well. Printed 3/22/89 1
XFD(1X11) COMMAND REFERENCE XFD(1X11) The displayed information includes the width of the character, its left bearing, right bearing, ascent, and its descent. If verbose mode is selected, typing '<' or '>' into the window will display the minimum or maximum values respectively taken on by each of these fields over the entire font. The font name is interpreted by the X server. To obtain a list of all the fonts available, use xlsfonts(1x11). The window stays around until the xfd process is killed or one of 'q', 'Q', ' ', or ctrl-c is typed into the xfd window. OPTIONS -display display Specifies the display to use. -geometry geometry Specifies an initial window geometry. -bw number Allows you to specify the width of the window border in pixels. -rv The foreground and background colors will be switched. The default colors are black on white. -fw Overrides a previous choice of reverse video. The foreground and background colors will not be switched. -fg color On color displays, determines the foreground color (the color of the text). -bg color On color displays, determines the background color. -bd color On color displays, determines the color of the border. -bf fontname Specifies the font to be used for the messages at the bottom of the window. -tl title Specifies that the title of the displayed window should be title. -in iconname Specifies that the name of the icon should be iconname.

XFD(1X11) COMMAND REFERENCE XFD(1X11) -icon filename Specifies that the bitmap in file filename should be used for the icon. -verbose Specifies that extra information about the font should be displayed. -gray Specifies that a gray background should be used. -start charnum Specifies that character number charnum should be the first character displayed. X DEFAULTS The xfd font displayer uses the following X resources: BorderWidth Set the border width of the window. BorderColor Set the border color of the window. ReverseVideo If ``on'', reverse the definition of foreground and background color. Foreground Set the foreground color. Background Set the background color. BodyFont Set the font to be used in the body of the window (i.e., for messages, etc.). This is not the font that xfd displays, just the font it uses to display information about the font being displayed. IconName Set the name of the icon. IconBitmap Set the file to look into for the icon bitmap. Title Set the title to be used. SEE ALSO X(1x11), xlsfonts(1x11), and xrdb(1x11). CAVEATS Character information displayed in verbose mode is sometimes clipped to the window boundary, hiding it from view. It should skip over pages full of nonexistent characters.
