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 * - -Call with the B<-v> option to see progress and debug messages. - -=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. - -=back - - -=head1 MISC - -=over 2 - -=item * - -Doesn't depend on the filename or extension of the input file. - -=item * - -Conversion from EPS to PDF: fixes glitches etc., calls gs --sDEVICE=pdfwrite - -=item * - -Conversion from EPS to EPS: fixes various glitches, moves (llx,lly) to -(0,0), removes binary junk from the beginning of the EPS etc. - -=item * - -Conversion from PDF to PDF: keeps the file intact - -=item * - -Conversion from PDF to EPS: calls pdftops -eps (of the xpdf package) - -=item * - -Conversion from PS to EPS: keeps 1st page only, removes setpagedevice etc. - -=back - -=head1 AUTHORS - -The author of B<a2ping> is Szabó Péter <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.
