Convert Text to an image

Text2Im converts a passed string to a bw-image.

Often it is necessary to burn in annotations in evaulated images. Since I didn't found an easy solution to do so, I wrote this programm to generate an image array which then can be easily integrated in an image arry (for example via implace.m from http://www.csse.uwa.edu.au/~pk/Research/MatlabFns/ ).
