1 pdfconcat

3

4 This program concatenates PDF files and optionally converts text

5 within them into bitmaps. The concatenation is done with Ghostscript (gs);

6 the detextification is done with a gs-conversion to tiff and tiff2pdf

7 (package libtiff-tools) afterwards. Detextification is only in gray-scale.

25 Installation:

26

27 You need a Unix system. Ensure you have gs and tiff2pdf (in the package

28 libtiff-tools) available.

29

30 To use the bin/pdf* tools on the command line only, copy them to your $PATH

31 and make them executable.

32

33 To set up the program including the web interface, copy the files to a place

34 below the webserver root. Make bin/pdf{concat,detextify} executable for

35 www-data. Make the log and the upload directory writable by www-data. Install

36 a cronjob to clean up the upload directory. Ensure that the max upload file

37 size of PHP is large enough.
