xfd - display all the characters in an X font
xfd [-options ...] -fn fontname
The xfd(1) 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(3)). 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(3)) 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 characters might not appear in their own grid cells. The -center option can be used to force all glyphs to be centered in their respective cells.
All of the characters in the font might 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(1), 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(1) for ways to generate lists of fonts, as well as more detailed summaries of their metrics and properties.
The xfd(1) utility accepts all of the standard toolkit command-line options, along with the additional following options:
To be written.
The program should skip over pages full of nonexistent characters.
