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.
