- PSTOEDIT
- Copyright (C) 1993 - 2000 Wolfgang Glunz, wglunz@geocities.com
-
- pstoedit converts Postscript(TM) and PDF files to other vector graphic
- formats so that they can be edited graphically. See pstoedit.htm or
- index.htm for more details on which formats are supported by pstoedit.
-
- The architecture of pstoedit consists of a PostScript frontend which
- needs to call a PostScript interpreter like Ghostscript and the
- individual backends which are plugged into a kind of framework.
-
- This framework can be used independently from the PostScript frontend
- from any other program. The framework provides a uniform interface to
- all different backends. Get in contact with the author if you need
- more information on how to use this framework.
-
- If you just find this program useful, have made some improvements or
- implemented other backends please send an email to wogl@geocities.com.
-
- If this programs saves you a lot of work consider sending a contribution
- of any kind.
-
- If you include this program on a CDROM, please send me a copy of the CD,
- or if it goes with a book, of the book.

- Compiling pstoedit:
- -------------------
- You need a C++ compiler, e.g., g++ to compile pstoedit.
-
- If you have a Unix like system, try the following:
- * cd config
- * sh configure
- * cd ../src; make clean; make; make install;
-
- If you have another system where running configure is not
- possible, e.g. Windows, do the following:
- * cd to src
- * edit the makefile.txt
- - change BINDIR according to your local environment
- - Uncomment the platform specific flags corresponding to your
- platform.
- * nmake /f makefile.txt (in a DOS box)
-
- * Note: pstoedit is configured to use the ANSI C++ headers. If your compiler
- support then ANSI C++ headers, you might try to compile with those. In
- this case #define HAVESTL in cppcomp.h
-
- A note regarding Visual C++. In principle the HAVESTL can be activated
- for Visual C++ (>= 5.0). However, I noticed a drastical increase both in
- compilation time and object size. This is probably due to the template
- based iostream library. Therefore I switched it off again. If you need
- the MetaPost backend under Windows, just turn the HAVESTL on and compile
- again.
-
-
- There are several test cases included. To run them type `make test'.
- This works under *nix only.
-
- Installing pstoedit under Windows 9x/NT:
- ----------------------------------------
-
- * create a directory "pstoedit" in parallel to the gsview directory, e.g.
- c:\gstools\pstoedit (if gsview is in c:\gstools\gsview )
- * copy the pstoedit.exe and pstoedit.dll to that directory.
- * if you plan to call pstoedit from a DOS box, you might consider to extend your
- PATH variable in order to avoid the need to call pstoedit always with with
- full path name.
- * if you have installed gsview 2.7 or later, you are done, if not you need
- to set the variable GS to point to either the gswin32.dll or gswin32c.exe found
- in the gsx.xx directory. In addition you might need to set GS_LIB (see GhostScript
- manual for details).
-
-
- pstoedit and the -dSAFER option of Ghostscript:
- -----------------------------------------------
- GhostScript provides an option -dSAFER that disables all file access
- functions of PostScript. Some administrators even install a wrapper
- like to following instead of ghostscript directly
- #!/bin/sh
- gs.real -dSAFER $*
-
- So when a user uses gs he/she actually runs this script. However,
- pstoedit needs to have access to files for it's operation. So
- it is not possible to use this wrapper for gs in combination with pstoedit.
- You would get an error message like "Error: /invalidfileaccess in (w)".
-
- As an alternative the following can be done:
- 1. Install the binary of pstoedit as pstoedit.real
- 2. Create the following wrapper and name it pstoedit
- #!/bin/sh
- GS=gs.real
- export GS
- pstoedit.real -include /??????/local/safer.ps $*
-
- A template for safer.ps can be found in the misc subdirectory.
- This way pstoedit can open all the file it needs (the input file and an
- output file). After that then -- via the included file -- all files
- operations are disabled and the input file is processed. Any file operation
- that is executed be the user's PostScript file is disabled this way.
-
-
- Using pstoedit:
- ---------------
- Before you can use pstoedit you must have a working installation
- of GhostScript (either GNU or Aladdin).
-
- The rest is descibed in the manual page in /pstoedit.htm.
-
- pstoedit works reasonable with PostScript files containing
- * line drawings
- * text with standard fonts
-
- Try to run it on golfer.ps or tiger.ps that comes with ghostscript, e.g.,
- pstoedit -f <your format> <local path where GhostScript is installed>/examples/tiger.ps tiger.<suffix>
-
- In particular pstoedit does not support
- * bitmap images (just for xfig and MIF)
- * general fill patterns
- * clipping (only partially via the -sclip option)
- * ...
-
- Special note about the Java backend:
- ------------------------------------
- The java backends generate a java source file that needs other files
- in order to be compiled and usable. See the files java/java1/readme_java.txt
- and java/java2/readme_java2.htm for more details.
-
- Extending pstoedit:
- -------------------
- To implement a new backend you can start from drvsampl.cc.
- Please don't forget to send any new backend that might be of interest
- for others as well to the author (wglunz@geocities.com) so that
- it can be incorporated into future versions of pstoedit. Such
- new backends will then be available with the GPL as well.
