2: .TH LOADFONT 1 "630 MTG"
3: .XE "loadfont"
4: .SH NAME
5: loadfont \- font managing program
6: .SH SYNOPSIS
7: .B
8: loadfont [\-r name,name...] [\-p directory] [\-s] [\-c] [file...]
9: .SH DESCRIPTION
10: The
11: .I loadfont
12: program lets the user load and remove fonts from the terminal's cache.
13: It will download its terminal side which interacts with
14: the user. The command line arguments have the following meanings:
15: .PP
16: .TP 12
17: \fB\-r\fR
18: Removes the given font from the terminal's cache.
19: .PP
20: .TP 12
21: \fB\-p\fR
22: Sets default search path for font files. If this isn't set,
23: it defaults to $DMD/termfonts. All the file names in this directory
24: are put in the load submenu.
25: .TP 12
26: \fB\-s\fR
27: Makes loadfont stay running after executing the earlier command line options.
28: .PP
29: .TP 12
30: \fB\-c\fR
31: Causes loadfont to be cached in the 630 MTG cache system. When
32: this option is used, the loadfont program will remain in the
33: terminal after the program exits. Then, the next time loadfont
34: is executed, it will not have to be downloaded again.
35: .sp
36: Another effect of downloading loadfont with the \-c option is
37: that it can be executed in more than one window without
38: additional downloading.
39: .PP
40: .TP 12
41: \fBfile\fR
42: Loads the given font file into the terminal's cache.
43: .PP
44: If a \f3file\f1 argument and/or the
45: \f3\-r\f1 option are given, loadfont will exit after
46: loading/removing the specified fonts, unless the \f3\-s\f1 is
47: also given to make it stay running.
48: .PP
49: The user interacts with
50: .I loadfont
51: by using a button 2 menu and, when prompted, the keyboard.
52: When button 2 is depressed, a menu with the following items appears.
53: .PP
54: .TP 8
55: \fBLoad\fR
56: Load has a submenu of fonts that can be downloaded.
57: The fonts listed are all the files in the default search directory.
58: If the first item, Keyboard, is selected, the user is prompted
59: for the name of a font file to download.
60: .PP
61: .TP 8
62: \fBRemove\fR
63: Remove has a submenu of all the fonts in the terminal's cache.
64: Selecting one will remove it from the cache and free the memory
65: it was using. Fonts in ROM or being used by another process
66: will be greyed in the menu and cannot be removed.
67: .PP
68: .TP 8
69: \fBQuit\fR
70: Will make the program exit.
71: .PP
72: While a font is downloading, the button 2 menu will have only
73: one item, Terminate Download. Selecting it will stop the download
74: and switch the user back to the original menu.
75: .PP
76: The three fonts in ROM, resident to the 630 MTG, are called "small
77: font," "medium font," and "large font." Brief descriptions of these
78: fonts follow.
79: .PP
80: In the tables,
81: .I cell size
82: indicates the dimensions of the rectangle containing the character
83: image. All the characters in a particular font have the same cell size.
84: .I Character size
85: is the dimension of the largest character in the font.
86: .I Max chars
87: indicates how many characters in that font size will fit
88: horizontally and vertically in a full screen
89: window. See the section on fonts in the
90: \f2630 MTG Software Development Guide\f1
91: for more information on font data structures.

197: .SH WARNING
198: .P
199: Fonts that do not have 128 characters require the proper
200: parity setting when used in the default window process in the
201: non-layers environment. This is needed because a mod is done
202: on characters received from the host with the number of
203: characters in the font being used.
204: .P
205: This implies that parity bits are ignored for fonts with
206: exactly 128 characters, since c&0x7F == c%128. Fonts with less
207: than 128 characters need identical parity settings on the host
208: and in the terminal so that parity bits get stripped properly.
209: Characters with more than 128 characters require 8 bits with
210: no parity on both the host and in the terminal, because the
211: eighth bit is used to access characters greater than
212: 128.
