-=head1 NAME
-
-a2ping.pl -- convert between PS, EPS and PDF and other page description
-formats
-
-=head1 SYNOPSIS
-
-Z<> B<a2ping.pl> [B<-->]B<help>
- B<a2ping.pl> [B<-->]B<doc>
- B<a2ping.pl> [I<options>] <I<inputfile>> [[I<outformat>:] I<outputfile>]
-
-=head1 DESCRIPTION
-
-B<a2ping> is a UNIX command line utility written in Perl that
-converts many raster image and vector graphics formats to EPS or PDF and
-other page description formats. Accepted input file formats are: PS
-(PostScript), EPS, PDF, PNG, JPEG, TIFF, PNM, BMP, GIF, LBM, XPM, PCX,
-TGA. Accepted output formats are: EPS, PCL5, PDF, PDF1, PBM, PGM, PPM,
-PS, markedEPS, markedPS, PNG, XWD, BMP, TIFF, JPEG, GIF, XPM.
-B<a2ping> delegates the low-level work to
-Ghostscript (GS), B<pdftops> and B<sam2p>. B<a2ping> fixes many glitches
-during the EPS to EPS conversion, so its output is often more compatible
-and better embeddable than its input.
-
-Without the C<--below> option, it is guarenteed to start at the 0,0
-coordinate. C<--below>, C<--hires> and C<-v> are recommended options.
-
-The page size is set exactly corresponding to the BoundingBox.
-This means that when Ghostscript renders it, the result needs no
-cropping, and the PDF MediaBox is correct.
-
-If the bounding box is not right, of course, you have problems. If you
-feed crap in, you get crap. But you can supply the
-B<--bboxfrom=compute-gs> option to make GS recompute the bounding box.
-
-The name of the input file doesn't matter -- B<a2ping> detects the file
-format based on the first few bytes of the file. The name of the output
-file matters if I<outformat> is missing from the command line: then the
-extension of the output file determines the FileFormat (I<outformat>).
-
-=head1 EXTERNAL PROGRAMS
-
-The internal file format of B<a2ping.pl> is PS/EPS. Everything read is
-first converted to PS or EPS, then processed by B<a2ping.pl>, then
-converted to the output format.
-
-To analyse the bounding box and other properties of non-EPS PS files
-(and EPS files with option B<--bboxfrom> other than B<=guess>), GS is
-used. Converting PS to EPS involves this analysis.
-
-To write PDF files, GS is used.
-
-To read PDF files, B<pdftops> from the B<xpdf> package is used.
-
-Sampled input formats are PNG, JPEG, TIFF, PNM, BMP, GIF, LBM, XPM, PCX
-and TGA. To read sampled input formats, B<sam2p> is used. B<sam2p> is
-a raster image converter written in C++ by the author of B<a2ping.pl>.
-
-Extra output formats are PNG, XWD, BMP, TIFF, JPEG, GIF and XPM. To
-write extra output formats, B<sam2p> and GS are used.
-
-PNM output formats are PGM, PGM and PPM. To write PNM output formats, GS
-is used.

-=head1 TIPS AND TRICKS
-
-=over 2
-
-=item *
-
-If your EPS contains a wrong bounding box, you can fix it by running
-C<a2ping.pl -v --bboxfrom=compute-gs thefile.eps -->
-
-=item *
-
-You can specify B<-> as I<inputfile> to get stdin and as I<outputfile>
-to get stdout. This works even for PDF files (which must be seekable),
-because B<a2ping> copies them to a temporary file automatically.
-
-=item *
-
-If I<inputfile> and I<outputfile> are the same, B<a2ping> copies the
-I<inputfile> to a temporary location first. However, this usage is
-recommended only if there is a backup of the file to be restored in case
-B<a2ping> doesn't produce the desired result.
-
-=item *
-
-If you specify B<--> as I<outputfile>, it will be the same as I<inputfile>.
-
-=item *
-
-B<a2ping> respects B<--Duplex> for FileFormat PCL5, even though GS doesn't.
-
-=item *
-
-If you have an incompatible PS that GS can read but your printer cannot print,
-just run C<a2ping.pl foo.ps PDF: - | a2ping.pl - PS: foo.ps>
-
-=item *
-
-If you have a PS coming from Win32 (often with extension C<.prn>), run
-it through B<a2ping>. It will remove the resolution changes and the
-progress text printed to the terminal (which confuses gv(1) and makes
-some filters in the print queue emit incorrect output).
-
-=item *
-
-B<a2ping> does antialiasing (B<--antialias=scale3no>) of glyphs and
-curves when emitting a sampled image (FileFormats such as PGM and PPM).
-This improves readability of the glyphs. B<=yes> instructs GS to do
-internal antialiasing, but it usually doesn't improve much. B<=scale3no>
-turns off GS internal antialiasing, but makes it render everything 3x3
-as big, and then scales it back down. B<=scale3no> turns on both 3x3
-scaling and GS internal antialiasing, which results in thicker lines and
-worse quality in general.
-
-=item *
-
-When creating a PBM file, antialiasing usually doesn't improve the
-quality, so it is switched off by default. But if you set
-B<--antialias=scale3no> or B<--antialias=scale3yes>, GS will render a PGM file,
-and the value of B<--threshold> determines the minimum intensity for white in
-the final PBM.
-
-=item *
-
-If you need a bigger sampled output file, specify a larger
-B<--Resolution>. The default is B<--Resolution=72>. If your sampled output file
-is going to be really big, you should specify B<--AntiAlias=yes> instead of
-the default B<--AntiAlias=scale3no> to speed up conversion.
-
-=item *
-
-To make sure fonts are included in a PDF file generated from eps, use
-B<--gsextra='-dEmbedAllFonts=true -dPDFSETTINGS=/printer'>.

-
-The author of B<a2ping> is Péter Szabó <F<pts@fazekas.hu>>.
-
-B<a2ping> is inspired by and historically based on the B<epstopdf> Perl
-script modified by Thomas Esser, Sept. 1998, but his modifications have
-been removed from B<a2ping>, and also B<a2ping> and B<epstopdf> do not
-share common code anymore. B<epstopdf> is written by Sebastian Rahtz,
-for Elsevier Science. B<epstopdf> contained extra tricks from Hans Hagen's
-texutil.

-B<a2ping> contains contributions from several people, see the file
-F<HISTORY.txt> for details. Thank you all for contributing!
