NAME

pstoedit - a converter from Postscript(TM) and PDF to editable Objects.

SYNOPSIS

pstoedit [ -help ] [ -bo ] [ -dt ] [ -dis ] [ -merge ] [ -flat number ] [ -s number (for tgif only) ] [ -nomaptoisolatin1 ] [ -nq ] [ -rn1xn2 ] [ -f format ] [ input file [ output file ] ]

DESCRIPTION

pstoedit converts Postscript(TM) and PDF files to a simple vector graphic format, that can be edited or imported into various drawing packages. To get a list of supported output formats type pstoedit -help.

Pstoedit works by redefining the two basic painting operators of (TM)Postscript, stroke and show. Other drawing operators, e.g., image are not supported. After redefining these operators, the Postscript or PDF file that needs to be converted is processed by a PostScript interpreter, e.g., GhostScript (gs). So you need to have a PostScript interpreter installed in order to use this program. If you want to process PDF files directly, the PostScript interpreter must provide this feature, as does GhostScript. The output that is written by the interpreter due to the redefinition of the drawing operators is a sort of flat PostScript file which only contains simple operations like moveto lineto, show, .... You can look at this file using the -f debug option.

This output is read by the backend part in pstoedit and triggers the drawing functions in the selected backend.

To implement a new backend you can start from drvsampl.cc and drvsampl.h. See also drvbase.h and drvfuncs.h for an explanation of the methods that need to be implemented for a new backend.

OPTIONS

-dt: Text is drawn as polygons. This might produce a large output file. You might want to use this options for example if the PostScript file contains rotated text and the backend does not support this, e.g., tgif.
-merge: Some backend support the representation of filled polygons with edges that are in a different color than the fill color. Since PostScript does not support this, drawing programs typically generate two objects (the outline and the filled polygon) into the PostScript output. pstoedit is able to recombine these, if they follow each other directly and you specified -merge.
-dis: Open a display during processing by GhostScript. Some files only work correctly this way.
-s factor: scale by a factor (for tgif only).
-f format: target output format. Currently tgif, mif, fig (for xfig), cgm, met (OS/2 only), wmf (Windows only), pdf, gnuplot, dxf, lwo, rib, rpl, java, dump, debug, and ps are recognized.
-flat number: If the backend does not support curves in the way PostScript does, all curves are approximated by lines. Using the the -flat option one can control this approximation. This parameter is directly converted to a PostScript setflat command.
-rn1xn2: This argument is passed directly to GhostScript. This causes the resolution to be changed to (n1,n2). This has an effect only if -diplay is set. Otherwise the resolution is 72dpi.
-nq: Normally Ghostscript stops after processing the pstoedit input file. For debugging it can be useful to avoid this. In this case you have to type 'quit' to the GS> prompt.
-nomaptoisolatin1: Normally pstoedit maps all character codes to the ones defined by the ISO-Latin1 encoding. If you specify -nomaptoisolatin1 then the encoding from the input PostScript is passed unchanged to the output.
-bo: You can run a backend only (without the PostScript interpreter frontend) by first running pstoedit -f dump infile dumpfile and then running pstoedit -f format -bo dumpfile outfile.
input file: input file.
output file: output file. If no output file is given as argument, pstoedit writes the result to standard output.
If neither an input nor an output file is given as argument, pstoedit works as filter reading from standard input and writing to standard output.

RUNNING ON OS/2

When running pstoedit on OS/2 you need to call it via the script ps2edit.cmd.

BACKEND SPECIFIC OPTIONS

pstoedit allows to pass individual options to a backend driver. This is done by appending all options to the format specifier after the -f option. The format specifier and the options must be separated by a :. If more than one option needs to be passed to the backend, the whole argument to -f must be enclosed within ".

Currently the met and the wmf driver are the only drivers accepting specific options.

The wmf driver supports two backend specific options. enhanced metafile instead of a normal metafile. pstoedit does not yet generate placeable metafiles. This will be added in one of the next releases.

ENVIRONMENT VARIABLES

A default PostScript interpreter that shall be called by pstoedit is specified at compile time. You can overwrite this default by setting the environment variable GS to the name of a suitable PostScript interpreter.

For getting some verbose output you can set the environment variable PSTOEDITVERBOSE to 1.
