Noli Turbare - Govert's Tools

Noli turbare circulos meos!

Marcellus gave out that Archimedes' life was to be spared. But as Archimedes was drawing diagrams with mind and eyes fixed on the ground, a soldier who had broken into his house in quest of loot with sword drawn over his head asked him who he was. Too much absorbed in tracking down his objective, Archimedes could not give his name but said, protecting the dust with his hands, "I beg you, don't disturb this," and was slaughtered as neglectful of the victor's command; with his blood he confused the lines of his art.

Govert's Tools

The tools that are presented on this site may be useful for people who plot, print and convert graphic files. Yes indeed, they are free, but a "thank you" in the guestbook, or a donation is always welcome. I give them away as I want to learn from suggestions for improvement and I don't want to limit the use to the small circle (hey...! noli turbare...!) around myself. Another good reason is that many parts are based on free code from other helpful people.

The rules: I made these tools for my own use (and fun). You may use them at your own risk. You should not expect professional support, though I often respond to questions, especially when they are clear and challenging... Nobody is allowed to make money by selling my tools. Nobody has distribution rights, except people or organizations to whom I explicitly granted these rights. This site is the only place where you should be able to find my tools. Links to this site are welcome, but it is NOT allowed to provide hotlinks to my files.


One more thing: DO NOT use a download manager to download my files. My files are relatively small and most download managers only cause trouble here.


Your comments, suggestions, questions, bugreports, or any other relevant words that you want to say are welcome here. You can also sign my guestbook and drop a comment (no questions) there. Some questions may have been answered in my FAQ.

Finally a remark about the images on this site. As far as I know they are royalty free, if you find some that are not, please let me know. Some were found here:, others here:
