1.1 ! root 1: .TH XFD 1 "12 June 1987" "X Version 11" ! 2: .SH NAME ! 3: xfd - X window system font displayer ! 4: .SH SYNOPSIS ! 5: .B xfd ! 6: [ =\fIgeometry\fP ] [ \fIhost\fP:\fInumber\fP ] [ options ] [ fontname ] ! 7: .SH DESCRIPTION ! 8: .I Xfd ! 9: creates a window which displays the characters in the named font. The ! 10: characters are displayed in increasing order from left to right and top to ! 11: bottom. The first character displayed at the top left will be character ! 12: number 0 unless the -start option has been supplied in which case the ! 13: character with the number given in the -start option will be used. ! 14: .PP ! 15: The characters are displayed in a grid of boxes, each large enough to hold any ! 16: character of the font. ! 17: If the -gray option has been supplied, the characters will be displayed using ! 18: XDrawImageString using the foreground and background colors on a ! 19: gray background. This permits determining exactly how XDrawImageString will ! 20: draw any given character. If -gray has not been supplied, the characters will ! 21: simply be drawn using the foreground color on the background color. ! 22: .PP ! 23: All the characters in the font may not fit in the window at once. ! 24: To see additional characters, click the right mouse button on the window. ! 25: This will cause the next window full of characters to be displayed. ! 26: Clicking the left mouse button on the window will cause the previous ! 27: window full of characters to be displayed. ! 28: .I Xfd ! 29: will beep if an attempt is made to go back past the 0th character. ! 30: .PP ! 31: Note that if the font is a 8 bit font, the characters 256-511 (0x100-0x1ff), ! 32: 512-767 (0x200-0x2ff), ... ! 33: will display exactly the same as the characters 0-255 (0x00-0xff). ! 34: .I Xfd ! 35: by default creates a window of size sufficient to display the first 256 ! 36: characters using a 16 by 16 grid. In this case, there is no need to scroll ! 37: forward or backward window fulls in order to see the entire contents of a 8 bit ! 38: font. Of course, this window may very well not fit on the screen... ! 39: .PP ! 40: Clicking the middle button on a character will cause that character's ! 41: number to be displayed in both decimal and hexidecimal at the bottom of the ! 42: window. If verbose mode is selected, additional information about that ! 43: particular character will be displayed as well. The displayed information ! 44: includes the width of the character, its left bearing, right bearing, ascent, ! 45: and its descent. If verbose mode is selected, typing '<' or '>' into the ! 46: window will display the minimum or maximum values respectively ! 47: taken on by each of these fields over the entire font. ! 48: .PP ! 49: The font name is interpreted by the X server. ! 50: To obtain a list of all the fonts available, use xlsfonts. ! 51: On a VAX, if the name ! 52: does not begin with ``/'', the X server adds the suffix ``.snf'' to it and ! 53: looks up the font file in the directory \fI/usr/new/lib/X/font/\fP. If ! 54: the name does begin with ``/'', the X server treats it as an absolute ! 55: pathname of a file containing a font. ! 56: .PP ! 57: If no font name is given on the command line, ! 58: .I Xfd ! 59: displays the font ``fixed''. ! 60: .PP ! 61: The window stays around until the xfd process is killed ! 62: or one of 'q', 'Q', ' ', or ctrl-c is typed into the ! 63: .I Xfd ! 64: window. ! 65: .SH "OPTIONS" ! 66: .PP ! 67: .TP 8 ! 68: .B \fIhost\fP:\fIdisplay\fP ! 69: Normally, ! 70: .I xfd ! 71: gets the host and display number to use from the environment ! 72: variable ``DISPLAY''. One can, however specify them explicitly. ! 73: The ! 74: .I host ! 75: specifies which machine to create the window on, and ! 76: the ! 77: .I number ! 78: argument specifies the display number. ! 79: For example, ! 80: ``orpheus:1'' creates a shell window on display one on the machine ! 81: orpheus. ! 82: .PP ! 83: .TP 8 ! 84: .B \-bw \fIborderwidth\fP ! 85: Allows you to specify the width of the window border in pixels. ! 86: .PP ! 87: .TP 8 ! 88: .B \-rv ! 89: The foreground and background colors will be switched. The default colors ! 90: are black on white. ! 91: .PP ! 92: .TP 8 ! 93: .B \-fw ! 94: Overrides a previous choice of reverse video, say in a .Xdefaults file. The ! 95: foreground and background colors will not be switched. ! 96: .PP ! 97: .TP 8 ! 98: .B \-fg \fIcolor\fP ! 99: On color displays, determines the foreground color. (the color of the text) ! 100: .PP ! 101: .TP 8 ! 102: .B \-bg \fIcolor\fP ! 103: On color displays, determines the background color. ! 104: .PP ! 105: .TP 8 ! 106: .B \-bd \fIcolor\fP ! 107: On color displays, determines the color of the border. ! 108: .PP ! 109: .TP 8 ! 110: .B \-bf \fIfontname\fP ! 111: Specifies the font to be used for the messages at the bottom of the window. ! 112: .PP ! 113: .TP 8 ! 114: .B \-tl \fItitle\fP ! 115: Specifies that the title of the displayed window should be \fItitle\fP. ! 116: .PP ! 117: .TP 8 ! 118: .B \-in \fIiconname\fP ! 119: Specifies that the name of the icon should be \fIiconname\fP. ! 120: .PP ! 121: .TP 8 ! 122: .B \-icon \fIfilename\fP ! 123: Specifies that the bitmap in file \fIfilename\fP should be used for the icon. ! 124: .PP ! 125: .TP 8 ! 126: .B \-verbose ! 127: Specifies that verbose mode should be used. ! 128: .PP ! 129: .TP 8 ! 130: .B \-gray ! 131: Specifies that a gray background should be used. ! 132: .PP ! 133: .TP 8 ! 134: .B \-start \fIcharnum\fP ! 135: Specifies that character number \fIcharnum\fP should be the first character ! 136: displayed. ! 137: .PP ! 138: .TP 8 ! 139: .B \=\fIgeometry\fP ! 140: .I Xfd ! 141: will also take a standard geometry specification (see X(1)). ! 142: .SH "X DEFAULTS" ! 143: .I Xfd ! 144: uses a number of standard default values. ! 145: .PP ! 146: .TP 8 ! 147: .B BorderWidth ! 148: Set the border width of the window. ! 149: .PP ! 150: .TP 8 ! 151: .B BorderColor ! 152: Set the border color of the window. ! 153: .PP ! 154: .TP 8 ! 155: .B ReverseVideo ! 156: If ``on'', reverse the definition of foreground and background color. ! 157: .PP ! 158: .TP 8 ! 159: .B Foreground ! 160: Set the foreground color. ! 161: .PP ! 162: .TP 8 ! 163: .B Background ! 164: Set the background color. ! 165: .PP ! 166: .TP 8 ! 167: .B Border ! 168: Set the color of the border. ! 169: .PP ! 170: .TP 8 ! 171: .B BodyFont ! 172: Set the font to be used in the body of the window.
