3 61f5c35c 2004-05-15 devnull * download - host resident font downloader
5 61f5c35c 2004-05-15 devnull * Prepends host resident fonts to PostScript input files. The program assumes
6 61f5c35c 2004-05-15 devnull * the input files are part of a single PostScript job and that requested fonts
7 61f5c35c 2004-05-15 devnull * can be downloaded at the start of each input file. Downloaded fonts are the
8 61f5c35c 2004-05-15 devnull * ones named in a %%DocumentFonts: comment and listed in a special map table.
9 61f5c35c 2004-05-15 devnull * Map table pathnames (supplied using the -m option) that begin with a / are
10 61f5c35c 2004-05-15 devnull * taken as is. Otherwise the final pathname is built using *hostfontdir (-H
11 61f5c35c 2004-05-15 devnull * option), *mapname (-m option), and *suffix.
13 61f5c35c 2004-05-15 devnull * The map table consists of fontname-filename pairs, separated by white space.
14 61f5c35c 2004-05-15 devnull * Comments are introduced by % (as in PostScript) and extend to the end of the
15 61f5c35c 2004-05-15 devnull * current line. The only fonts that can be downloaded are the ones listed in
16 61f5c35c 2004-05-15 devnull * the active map table that point the program to a readable Unix file. A request
17 61f5c35c 2004-05-15 devnull * for an unlisted font or inaccessible file is ignored. All font requests are
18 61f5c35c 2004-05-15 devnull * ignored if the map table can't be read. In that case the program simply copies
19 61f5c35c 2004-05-15 devnull * the input files to stdout.
21 61f5c35c 2004-05-15 devnull * An example (but not one to follow) of what can be in a map table is,
24 61f5c35c 2004-05-15 devnull * % Map requests for Bookman-Light to file *hostfontdir/KR
27 61f5c35c 2004-05-15 devnull * Bookman-Light KR % Keeping everything (including the map
28 61f5c35c 2004-05-15 devnull * % table) in *hostfontdir seems like the
29 61f5c35c 2004-05-15 devnull * % cleanest approach.
32 61f5c35c 2004-05-15 devnull * % Map Palatino-Roman to file *hostfontdir/palatino/Roman
34 61f5c35c 2004-05-15 devnull * Palatino-Roman palatino/Roman
36 61f5c35c 2004-05-15 devnull * % Map ZapfDingbats to file /usr/lib/host/dingbats
38 61f5c35c 2004-05-15 devnull * ZapfDingbats /usr/lib/host/dingbats
40 61f5c35c 2004-05-15 devnull * Once again, file names that begin with a / are taken as is. All others have
41 61f5c35c 2004-05-15 devnull * *hostfontdir/ prepended to the file string associated with a particular font.
43 61f5c35c 2004-05-15 devnull * Map table can be associated with a printer model (e.g. a LaserWriter), a
44 61f5c35c 2004-05-15 devnull * printer destination, or whatever - the choice is up to an administrator.
45 61f5c35c 2004-05-15 devnull * By destination may be best if your spooler is running several private
46 61f5c35c 2004-05-15 devnull * printers. Host resident fonts are usually purchased under a license that
47 61f5c35c 2004-05-15 devnull * restricts their use to a limited number of printers. A font licensed for
48 61f5c35c 2004-05-15 devnull * a single printer should only be used on that printer.
50 61f5c35c 2004-05-15 devnull * Was written quickly, so there's much room for improvement. Undoubtedly should
51 61f5c35c 2004-05-15 devnull * be a more general program (e.g. scan for other comments).
