Links

Here are some links to other programs useful, in one way or another, for desktop publishing sorts of tasks. The Inkscape and Scribus sites in particular both have many useful links to such things, and lively and informative discussion lists and wikis.

Indispensible Artsy Software

The Gimp
Image editor, since 1996! Huge user base, and tons of plugins available.
   www.gimp.org
Krita
A rapidly evolving image editor, roughly in the same category as the Gimp, but with more of an emphasis on painting. Features many exciting tools and abilities such as 16 bit images, wraparound editing, symmetry editing, and robust brush configurability.
   www.krita.org
Mypaint
Amazing software for drawing. Minimal interface, but powerful brush engine.
   mypaint.intilinux.com
Inkscape
Vector graphics via svg. Some day, you will be able to make animation with this.
   www.inkscape.org
Imagemagick Utilities
Command line tools to do a plethora of image tinkering.
   www.imagemagick.org
Graphicsmagick Utilities
Very similar to Imagemagick from which it forked, but implemented differently in places.
   www.graphicsmagick.org
Scribus
Capable DTP, though a bit slow for large, image heavy documents. Extensive PDF abilities. In terms of functionality, what's missing is impositioning.
   www.scribus.net
FontForge
A powerful font creation program. If you want to make fonts with open source software, for a very long time, this was your only option. These days, there are a variety of emerging contenders like Metapolator and Trufont. Be sure to set aside a fair amount of time to learn the interface.

Other Artsy Software

In addition to the Indispensible stuff above:
TeX/LaTeX
The quintessential, very powerful layout engine. Works from text configuration files.
   tug.org  
Darktable
An image effect processor. Mass edit photos from your camera to get color settings more to your liking.
   darktable.org  
Raw Therapee
Another image effect processor, similar in use to Darktable.
   rawtherapee.com  
Podofo
A set of tools to help process PDF files. Podofoimpose, for instance, imposes PDF documents using a plan file based on a minimal lua based syntax. There is also Podofobrowser, which is a great low level browser of the contents of PDF files.
   podofo.sourceforge.net  
Lyx
Kind of a graphical front end for TeX/LaTeX
   www.lyx.org  
LibreOffice
Forked from Openoffice in 2010, when Oracle bought Sun. Most of the OpenOffice devs switched over to LibreOffice. Oracle later sold off OpenOffice to Apache.
   www.libreoffice.org
OpenOffice.org
Like LibreOffice, the Writer component is basically just a word processor, but frequently useful, especially for dealing with MS Word documents.
   openoffice.org
Calligra Words
Formerly Kword, an easy word processor. MUCH smaller than Libreoffice. Its file format these days is odf, like LibreOffice.
   www.calligra.org/words
Passepartout
(pronounced pus-par-too)
Exemplary straightforward gui for simple wrapped text and images. Very simple and easy file format. Has phenomenal, unmatched "Inspiration" button. It is very important for software to inspire the proper work ethic, and the Inspiration option does that admirably by allowing you to play a mini-game of worms! No longer in development.
   www.stacken.kth.se/project/pptout
Psutils
Command line utilities to perform various things like booklet impositioning on postscript files
   www.tardis.ed.ac.uk/~ajcd/psutils/index.html
Processing
Relatively simple java based programming environment that greatly streamlines creation of strange tools as well as animation.
   processing.org
Flat+Even
Another programming environment for visual elements. This one for python lets you write code to generate lines, shapes, pull in images, and flow text in areas with pleasant line breaking, across multiple pages! Flat is the python side, and Even is the real time viewer.
   xxyxyz.org
Boomaga
Kind of a last step before the printer actually prints, this is a virtual printer that takes a print job and can rearrange into booklets.
   github.com/Boomaga/boomaga
