Ubuntu is composed of many software packages, the vast majority of which are distributed under a free software license. The only exceptions are some proprietary hardware drivers.The main license used is the GNU General Public License (GNU GPL) which, along with the GNU Lesser General Public License (GNU LGPL), explicitly declares that users are free to run, copy, distribute, study, change, develop and improve the software. On the other hand, there is also proprietary software available that can run on Ubuntu. Ubuntu focuses on usability, security and stability. The Ubiquity installer allows Ubuntu to be installed to the hard disk from within the Live CD environment, without the need for restarting the computer prior to installation. Ubuntu also emphasizes accessibility and internationalization to reach as many people as possible.

Flpsed a postscript and PDF annotator on Ubuntu.

Friday, March 15, 2013

Flpsed is a WYSIWYG PostScript annotator. You can't remove or modify existing elements of a document. But flpsed lets you add arbitrary text lines to existing PostScript documents (PostScript is a registered trademark of Adobe Systems Incorporated). Added lines can later be reedited with flpsed.

Using pdftops, which is part of xpdf one can convert PDF documents to PostScript and also add text to them. flpsed is useful for filling in forms, adding notes etc. GsWidget is now part of flpsed. 

flpsed is released under the


fltk-1.3.x based version: flpsed-0.7.0.tar.gz
sha1 7966fd3b6fb3aa2a376386533ed4421ebb66ad62

flpsed is also available as debian package, openSUSE package, and FreeBSD port.

Source Repository

A mercurial repository can be found here.


  • Add arbitrary text to existing PostScript documents.
  • Reedit text, that has been added with flpsed.
  • The overall structure of the PostScript document is not modified. flpsed only adds the additional text.
  • Batch processing (no X11 required) to modify tagged text lines that have been entered interactively with flpsed before. This is very useful for repeatedly filling in forms.
  • Text lines can be imported from other flpsed-modified documents.
  • Import and export PDF. Therefore it can be used as a PDF editor as well.



Changes from 0.5.3 to 0.7.0

  • Detect pdf by looking at magic number instead of file extension.
  • Bring in utf8 changes from fltk2 based version to make it work with fltk-1.3. flpsed is now officially based on fltk-1.3.x.
