The -problem with bitmapped fonts is that they target a specific device -resolution; a PostScript file produced using S<300 DPI> fonts will -look grainy on a S<600 DPI> printer. Even worse, I<all> bitmapped -fonts look grainy when zoomed in on screen. The solution is to use -vector (PostScript S<Type 1>) fonts, which are resolution-independent -and appear crisp at any size or scale. - -While it is no longer difficult to configure B<dvips> to use vector -fonts, it is not always possible to rerun B<dvips> on an old F<.dvi> -file. The F<.dvi> file and document source may have been lost; or, -the source may no longer compile because packages it depends upon may -no longer be available. - -Heiko Oberdiek's B<pkfix> script replaces bitmapped fonts in -B<dvips>-produced PostScript files with the corresponding vector -fonts. It works by parsing the PostScript comments with which -B<dvips> surrounds bitmapped-font definitions. For example, a font -definition beginning with the comment C<%DVIPSBitmapFont: Fi cmss10 11 -28> and ending with a matching C<%EndDVIPSBitmapFont> is known to -define font C<Fi> as C<cmss10> (Computer Modern Sans Serif at a design -size of S<10 points>) scaled to S<C<11> points>. Only the C<28> -characters actually used by the document are defined. B<pkfix> then -replaces the font definition with one that defines C<Fi> using the -same set of characters but taken from the F<cmss10.pfb> vector font -file. - -Unfortunately, B<pkfix> works only with versions of B<dvips> newer -than v5.58 S<(ca. 1996)>. Naturally, the older a PostScript document, -the less likely its sources still exist and can still be recompiled. -Older versions of B<dvips> lack C<%DVIPSBitmapFont> comments and -various other PostScript comments on which B<pkfix> relies. Without -PostScript comments to guide it, B<pkfix> is unable to determine which -vector fonts correspond with which bitmapped fonts. - -=head2 Overview - -The B<pkfix-helper> script is a preprocessor for B<pkfix> that -attempts to determine the association between each document-font name -S<(e.g., C<Fi>)> in a PostScript file and the original font S<(e.g., -C<cmss10>)> and fonts size (e.g., S<C<11> points>). It then -fabricates the PostScript comments that B<pkfix> expects to see so -that B<pkfix> can do its job. - -B<pkfix-helper> works by comparing every document font against every -F<.tfm> font file it knows about (assuming that each such font has a -corresponding F<.pfb> vector version) and selecting the best matching -F<.tfm> file for every document font. B<pkfix-helper> has access only -to the widths of characters and only to those characters actually used -in the document. Also, the program recognizes only a limited set of -the most popular F<.tfm> files and scaling factors. Consequently, the -comparison is imperfect and B<pkfix-helper> may attribute an incorrect -font to a given name. Fonts comprising only one or two characters -actually used in a document are particularly problematic for -B<pkfix-helper> because many fonts may be near-enough matches to fool -the problem. - -B<pkfix-helper> is designed so that a user can guide the -font-selection process by manually designating matching fonts. With a -modicum of diligence and patience a user can correct any mismatched -fonts and help the program provide proper input to B<pkfix>. - - -=head1 OPTIONS - -B<pkfix-helper> accepts on the command line the filename of a -PostScript document to process (with the default being the standard -input device) and the filename of a modified PostScript document to -create (with the default being the standard output device). The -program also accepts the following command-line options: - -=head2 Frequently Used Options - -=over 4 - -=item B<-h>, B<--help> - -Display usage information and exit. The B<--verbose> and B<--quiet> -options can be used to increase and decrease the amount of information -presented. - -=item B<-v>, B<--verbose> - -Increase the amount of status information that B<pkfix-helper> -displays as it runs. Additional instances of B<--verbose> on the -command line further increase the program's verbosity. By default, -only major operations are displayed. A single B<--verbose> -additionally displays information about individual font comparisons. -A second B<--verbose> additionally displays details about some of the -program's internal operations. - -=item B<-f> I<name>=I<fontspec>, B<--force>=I<name>=I<fontspec> - -Force B<pkfix-helper> to associate a specific font with a given font -name appearing the document. I<name> is a two-character B<dvips> font -name such as C<Fa>. I<fontspec> is a font specification such as -S<C<cmsy10 @ 1.1X>>. The B<--force> option can be specified -repeatedly on the command line. - -=item B<-p> I<filename.ps>, B<--ps>=I<filename.ps> - -Create a PostScript file called I<filename.ps> that shows the B<dvips> -name and a font sample of every font used by the input document. - -=item B<-t> I<filename.tex>, B<--tex>=I<filename.tex> - -Create a Plain TeX file called I<filename.tex> that shows the B<dvips> -name and a font sample of every font that B<pkfix-helper> used in the -output document. - -=back - -=head2 Infrequently Used Options - -=over 4 - -=item B<-C> I<filename>, B<--cache>=I<filename> - -Speed up TFM file processing by caching character metrics into file -I<filename>. On some systems it takes a long time to read a TFM file, -spawn F<tftopl> to convert it to PL format, and extract from the PL -data the metrics for each character. The first time B<--cache> is -specified, B<pkfix-helper> proceeds as normal then writes all of the -extracted character metrics to I<filename>. On subsequent runs in -which B<--cache>=I<filename> is specified, B<pkfix-helper> reads the -previously extracted metrics from I<filename>, going through the -F<tftopl>-based process only for TFM files that were not previously -encountered. - -=item B<-i> I<fontspec>, B<--include>=I<fontspec> - -Add I<fontspec> to the list of font specifications against which -B<pkfix-helper> compares I<every> document font. (In contrast, -B<--force> designates a font specification to use only for a -I<specific> document font.) The B<--include> option can be specified -repeatedly on the command line. - -=item B<-x> I<regexp>, B<--exclude>=I<regexp> - -Remove all font specifications matching regular expression I<regexp> -from B<pkfix-helper>'s list of known fonts. The B<--exclude> option -can be specified repeatedly on the command line. - -=item B<-q>, B<--quiet> - -Instruct B<pkfix-helper> to produce no output during its run except -for fatal error messages. - -=item B<-1>, B<--no-repeats> - -Prevent B<pkfix-helper> from associating the same I<fontspec> with -more than one B<dvips> font name. - -=item B<-s>, B<--spp> - -Specify the number of font samples per page to print to the files -indicated using the B<--ps> and B<--tex> options. The default -S<value, 25,> should work well in most circumstances. - -=back - - -=head1 DIAGNOSTICS - -=over 4 - -=item C<Best match for I<name> is rather poor> - -The best font B<pkfix-helper> found for B<dvips> font name I<name> has -a mismatch value greater than or equal S<to 1.0>. (The mismatch value -is the sum of the squares of the difference between the character -widths of a document font and a potential replacement font.) Use the -B<--force> option to designate an alternative replacement font or -scaling amount. - -=back - - -=head1 EXAMPLES - -For the purpose of the following examples, assume that F<oldfile.ps> -is the name of a PostScript file produced by an old version of -B<dvips> and utilizing at least one bitmapped font.

Fortunately, -B<pkfix-helper> allows C<*> to be used as a scaling factor to tell the -program to automatically detect an optimal scaling factor, even if -doing so means choosing a highly nonstandard font size: - - $ pkfix-helper oldfile.ps pkfix-oldfile.ps --force="Ff=cmb12 @ *" - Reading netpipe.ps ... done. - Number of Type 3 fonts encountered: 10 - Bitmapped fonts are typeset at 600 DPI. - Finding character widths ... done. - Reading TFM files ... failed. - pkfix-helper: Unable to process user-specified TFM file "cmb12" - -Oops, it looks like we don't have a F<cmb12.tfm> file on our system. -Let's try scaling up F<cmb10.tfm> instead: - - $ pkfix-helper oldfile.ps pkfix-oldfile.ps --force="Ff=cmb10 @ *" - Reading netpipe.ps ... done. - Number of Type 3 fonts encountered: 10 - Bitmapped fonts are typeset at 600 DPI. - Finding character widths ... done. - Reading TFM files ... done (103 TFMs in 193 scaling variations). - Matching fonts: - Processing Fi ... done (cmr10 @ 1X, mismatch=0.11683). - Processing Fa ... done (cmti10 @ 1X, mismatch=0.08892). - Processing Fb ... done (cmr8 @ 1X, mismatch=0.07133). - Processing Ff ... done (cmb10 @ 1.5708X, mismatch=0.00035). - Processing Fh ... done (cmtt10 @ 1X, mismatch=0.06895). - Processing Fd ... done (cmmi10 @ 1X, mismatch=0.03966). - Processing Fj ... done (cmbx12 @ 1X, mismatch=0.03972). - Processing Fe ... done (cmbx10 @ 1X, mismatch=0.00762). - Processing Fg ... done (cmsy10 @ 1X, mismatch=0.00875). - Processing Fc ... done (cmr6 @ 1X, mismatch=0.00284). - -The match has definitely improved, although S<15.708 pt.> is certainly -an odd size for a font. Then again, many documents I<do> use -nonstandard sizes so this may in fact be correct. The best way to -verify is once again to produce, print, and compare a pair of font -samples and iterate until all of the fonts look correct. Use one -instance of B<--force> for each font you want to alter. - - -=head1 ENVIRONMENT - -B<pkfix-helper> honors the following environment variables: - -=over 8 - -=item GS - -The name of the Ghostscript interpreter (default: F<gs>) - -=item TFTOPL - -The name of a utility for converting F<.tfm> files to F<.pl> files -(default: F<tftopl>) - -=back - - -=head1 BUGS - -Even when B<pkfix-helper> finds a perfect match S<(i.e., the> correct -font in the correct size) the mismatch value is still typically -nonzero. The same error is probably what causes B<pkfix-helper> -sometimes to consider the wrong font as being a better match than the -correct font. Suggestions for fixing these bugs are welcome. - - -=head1 RESTRICTIONS - -B<pkfix-helper> works only with PostScript files produced by B<dvips>, -not with arbitrary PostScript files. The program has not been tested -with output from versions of B<dvips> older than v5.490 S<(ca. 1992)>; -output from older versions may or may not work. Only bitmapped fonts -loaded by B<dvips> can be analyzed, not bitmapped fonts loaded by -embedded graphics. - -B<pkfix-helper> works by comparing character widths, not the actual -glyphs. Consequently, it is misled by sets of fonts with similar -character widths (at least for those characters used by a given -document). As an extreme example, all Computer Modern Teletype fonts -of a given design size (e.g., C<cmtt10>, C<cmsltt10>, and C<cmitt10>) -use exactly the same widths for all characters. Human assistance is -generally needed to guide B<pkfix-helper>'s font-matching procedures. - - -=head1 NOTES - -Files produced using the B<--tex> option are Plain TeX files and -therefore must be compiled with F<tex> (or a variation such F<etex>, -F<pdftex>, F<pdfetex>, etc.), I<not> with F<latex>. - - -=head1 SEE ALSO - -pkfix(1), dvips(1), tex(1), gs(1) - -PostScript Language Reference, Third Edition. -Published by Addison-Wesley, ISBN 0-201-37922-8, -L<http://www.adobe.com/products/postscript/pdfs/PLRM.pdf>. - - -=head1 AUTHOR - -Scott Pakin, I<scott+pkfh@pakin.org> - - -=head1 COPYRIGHT AND LICENSE - -Copyright (C) 2009, Scott Pakin - -This file may be distributed and/or modified under the conditions of -the LaTeX Project Public License, either version 1.3c of this license -or (at your option) any later version.
