To make images and animated images we use the open source program GIMP. This program let us manipulate any pictures we need. GIMP let us read, manipulate, save and convert any imageformat to another
Normally we make SVG images or animations by hand as we know the standard very well, but complicated SVG images we sometime use Inkscape to make the base and then ajust the image by hand.
nkscape is a free and open-source vector graphics editor. It can create or edit vector graphics such as illustrations, diagrams, line arts, charts, logos and complex paintings. Inkscape's primary vector graphics format is Scalable Vector Graphics (SVG) version 1.1. While Inkscape can import and export several formats, all editing workflow inevitably occur within the constraints of the SVG format.
Sometime our customers ask us to make a simple publication on paper. To do this we use Scribus.
Scribus is a desktop publishing (DTP) application, released under the GNU General Public License as free software. It is based on the free Qt toolkit, with native versions available for Linux, Unix-like operating systems, Mac OS X, Haiku, Microsoft Windows, OS/2 and eComStation.
Scribus is designed for layout, typesetting and to prepare files for professional-quality image-setting equipment. It can also create animated and interactive PDF presentations and forms. Example uses include writing newspapers, brochures, newsletters, posters and books.
The office-suite we use is LibreOffice which contains all the tools other offfice-suites consist of, and more.
We use the LibreOffice spreadsheet (Calc) extensively in collecting large datasets other sources.
