45 duncan RedHat Print filters added to CVS tree
46 ajv Fixed -v and moved yet another global into a struct
47 20000306 duncan Lots of little fixes; --fd working right now;
48 bidirectional shearing adjustments added (user
49 configurable entries "blackshear" and colorshear"
50 in pnm2ppa.conf.
51 20000311 duncan added : -B n option and "blackness n" config file
52 entry to control black ink density (drops per
53 pixel n = 0,1,2,3,4 ) default is 2. Also there are
54 now config file entries blackshear and colorshear
55 for adjusting shearing in bidirectional printing.
56 Fixed various bugs that broke HP820/1000 printing.
57 20000318 duncan Color EcoMode printing now uses bidirectional
58 printsweeps (formerly only FastMode did this)
59 If gMaxPass = 1, you now get bidirectional sweeps
60 (in cut_im_color_swath() , cutswath.c)
61 20000326 duncan ** changes to dither.c:
62 on odd lines, black is
63 now processed (not color), even black pixels are
64 duplicated, so if either of two successive pixels are
65 black, they both are. Changes also fix Tim's report
66 about blurry black/white boundaries.
67 ** changes to image.c
68 If the odd line is not printed
69 (PixMap or EcoMode), image.c now stores the line, and
70 adds the black parts to the next even line.
71 This fixes a bug in where thin (one-pixel wide) black
72 lines (like enscript borders) could be lost because
73 black ink only printed every second pixel, and odd
74 black lines were just copies of the preceeding even
75 line which had been stored.
76 20000331 duncan added support for large papersizes 11x17 and a3
77 (for the 1000 series printers). Added a
78 printer-specific max_pagewidth so papersizes that
79 are too wide for a printer series will not print
80 on that printer.
81 20000402 duncan tweaked bidirectional sweep shearing correction.
82 (removed the +1 right-to-left black shift in
83 cut_im_black_swath() in cutswath.c ).
84 I am not sure if the shearing correction is
85 model or individual printer-specific. (I suspect
86 the second case, in which case it is a calibration
87 issue (The HP Win9x software seems to have calibration
88 adjustments for blackshear.) if any corrections
89 turn out to be generic to a given printer family,
90 (rather than specific to a particular printer)
91 the default can be changed in defaults.h (the
92 variables are:
93 printer->r2l_bw_offset (=blackshear)
94 printer->r2l_color_offset (=colorshear).
95 20000404 duncan added support for pbmraw and pgmraw formats.
96 all three pnmraw formats now work.
97 (changes in image.c, image.h )
98 20000405 duncan added support for pgm, ppm, pbm nonraw formats.
99 added papersize autoconfiguring from the pnm
100 header, so all ghostscript papersizes are now
101 supported (if the printer can accomodate them)
102 The -s option now only controls the gammafile
103 creation papersize. Made bidirectional
104 printing the default (but this can be configured
105 with a "unimode 1" in pnm2ppa.conf, or --uni,
106 --bi command line options.
107 20000408 duncan graceful termination of print run if pnm
108 input is truncated (i.e., if read_line()
109 encounters EOF). printer no longer hangs.
110 Moved text strings to lang.h/text-en.h
111 20000423 duncan clean up way things near sides of swath are
112 handled in cutswath.c
113 20000710 duncan in FS_Color_Dither(), use line[]= (1,1,1)
114 not (0,0,0) for black replacement of dark
115 pixels for which no color match is found.
116 (fixes flashing LED on certain images - those with
117 no black - with --eco on HP820)
118 (0,0,0) = black ink, (1,1,1) = gMaxPass drops of
119 each color.
120 20000928 duncan in cutswath.c, if the vertical position
121 of the black and color sweeps differed by 1 , 2 or 3
122 dots, HP820 got "flashing light syndrome".
123 Fixed by testing for this possibility, and
124 if found, by reducing numlines, and padding the top
125 of a swath with an (even) number of blank lines
126 to keep the height the same.
127 (Thanks to Steven Elliott <selliott4@austin.rr.com>
128 for reporting this bug, and testing the fix.
129 20001010 ajv made input of paths to gamma and config files secure
130 against buffer overruns.
131 duncan In -g mode, check that gamma.ppm is not a symbolic
132 link, and is a regular file, before writing to it
133 (but after opening it).
134
135 20001018 duncan clean up calibration program. now called
136 calibrate_ppa. It does most calibration now.
137
138 moved the job of writing gamma.ppm for color
139 calibration to a new utility calibrate_ppa.c.
140 pnm2ppa -g now just prints the corresponding
141 test page.
142
143 secured syslog messages. No user input is
144 sent to syslog. syslog messages are wrapped, and can
145 be suppressed with a new keyword "silent 1"
146 in /etc/pnm2ppa.conf (but not in subsequently-read
147 config files). all syslog activity now occurs
148 in syslog.c.
149 20001106 reduce memory footprint of calibrate_ppa
150 (it was 36MB!).
151 20001112 fix syslog silent/verbose usage; fix alignment
152 pattern bug in calibrate_ppa. repaired the HP820
153 fix that got broken when the vertical offset was
154 redefined by 600 dots...

1 ---------------------------------------------------------------------
2
3 Notes on secure installation of pnm2ppa.
4
5 What pnm2ppa does:
6
7 1. It attempts to open and read a configuration file
8 "/etc/pnm2ppa.conf", and then any additional configuration
9 files with paths specified by the -f command line option.
10
11 These paths are checked to be shorter than MAXPATHLEN before
12 they are used, otherwise pnm2ppa terminates.
13
14 GNU getopt() is used to process options.
15
16 2. It opens an input file (-i option) to receive pnm data.
17 The pnm format and page size is taken from the header.
18
19 If the header does not correspond to a valid pnm format, the rest
20 of the data is rejected, and pnm2ppa terminates.
21
22 The input file path is checked to have a length less than
23 MAXPATHLEN, as determined at compilation time.
24
25 3. It opens an output file (-o option) to send ppa data
26 (for the printer).
27
28 The output file path is checked to have a length less than
29 MAXPATHLEN.
30
31
32 4. (unless the --noGamma option is specified) it tries to read color
33 correction data from "/etc/pnm2ppa.gamma", or an alternate file with
34 a path specified by the -F command line option.
35
36 Such paths are also checked to be shorter than MAXPATHLEN before
37 they are used.
38
39 If this data exists, but is not successfully read, pnm2ppa terminates.
40 (See COLOR.txt).
41
42 5. pnm2ppa opens and writes to the syslog with informational messages
43 about its progress, or, if it terminates, with an error message.
44 If it is working in --verbose mode, these messages are also sent
45 to stderr.
46
47 No strings derived from user input to pnm2ppa are included in syslog
48 messages. Syslog messages must fit in a string of length < 128.
49 They can be suppressed with a keyword "silent 1" in the default
50 system configuration file (/etc/pnm2ppa.conf), but not from
51 user-specified config files (from -f option).
52
53 All syslog actions by pnm2ppa are "wrapped": message strings
54 produces in the rest of the program are only sent to the syslog by
55 code in syslog.c. This is also where openlog() and closelog() are
56 called.
57
58
59 ----------------------------------------------------------------------
60 Recommendations:
61
62 -- do *NOT* install pnm2ppa suid/guid, if is possible that a
63 "malicious user" might run it. The output file specified
64 with the -o option could overwrite files to which the user
65 has no write permission.
66
67
68 -- since pnm2ppa works as an output filter for gs, it only needs the
69 same privileges that gs would need. If lpr is available, pipe
70 the pnm2ppa output though "lpr -l ..." to the appropriate printer
71 rather than directly sending it to e.g. /dev/lp0 (in the latter case,
72 write privileges on /dev/lp0 would be needed.)
73
74 --------------------------------------------------------------
75
76 Other (optional) programs in the distribution:
77
78 Do NOT install these suid/gid!
79
80 calibrate.c: This is used to produce various ppmraw format PixMap images
81 used with pnm2ppa for printer calibration. Note: these
82 PixMaps are LARGE (100MB!!) and should generally be piped
83 directly to pnm2ppa.
84
85 THIS SHOULD USUALLY BE INSTALLED.
86
87 parse_vlink.c a utility useful in debugging pnm2ppa that can interpret
88 ppa format output instructions to the printer, whether
89 produced by pnm2ppa, or captured from the Windows9x drivers.
90 It is in the ppa_protocol subdirectory, and is not compiled
91 by default.
92
93 THIS IS NOT USUALY INSTALLED.
