A FreeBSD program that rotates text

[Polytropon]

Dear list,

I'm searching for a FreeBSD based means to align text in
a circle, adjusted like in a sigulum.

I've tried to find an option in OpenOffice, but failed.
Can anyone name me a program that can be used to do so?
It can even be LaTeX, or a painting program that lets
me construct a sigulum, like this:

http://www-e.uni-magdeburg.de/ruge/verschiedenes/medien-als-manipulatoren/otto.gif

Text at the top should be adjustable with its bottom
towards the inner of the circle, text at the circle's
bottom hould be adjustable with the bottom to the outer
perimeter of the circle so both text is "standing up".

A pictural figure should be placable in the inner of
the circle. Colours should be applyable.

Final output can be everything: Image formats like
PNG or JPG, PDF files, Postscript.

Suggestions, anyone? =^_^=



Thank you!
