dosepsbin -- Extract PS/WMF/TIFF sections from DOS EPS binary files

2012-03-22 v1.2

The progam dosepsbin analyses an EPS file that is not a plain ASCII PostScript file but given as DOS EPS binary file.

dosepsbin [options] <input file>

First it analyzes the input file, validates its header and summarizes the available sections. Depending on the given options, the sections are then written to files.

Options:

--eps-file <file>      Write PS section to <file>.
--wmf-file <file>      Write WMF section to <file>.
--tiff-file <file>      Write TIFF section to <file>.
--inputfile <file>     The name of the input file.
--verbose              Verbose output.
--quiet                Only errors and warnings are printed.
--help                 Brief help message.
--man                  Full documentation.
--version              Print version identification.

The files for output must be different from the input file.

DOS EPS Binary File Format

A Encapsulated PostScript (EPS) file can also given in a special binary format to support the inclusion of a thumbnail. The file format starts with a binary header that contains the positions of the possible sections:

* Postscript (PS)
* Windows Metafile Format (WMF)
* Tag Image File Format (TIFF)

The PS section must be present and either the WMF file or the TIFF file should be given.

The PS section is written to <file>. The output file must be different from the input file.
The WMF section is written to <file> if present. The output file must be different from the input file.
The TIFF section is written to <file> if present. The output file must be different from the input file.
The input file can also be given directly on the command line. If the file does not exist, then the file with extension `.eps' is tried.
Verbose messages.
No messages are printed except for errors and warnings.
Display help screen.
Prints manual page.
Print version identification and exit.

The following command extracts the PS section from file test.eps and stores the result in file test-ps.eps:

dosepsbin --eps-file test-ps.eps test.eps
