Rotating Images

[Jorge_Stolfi]

What programs do other people use for working with Voynich images?

I use Gimp for visualization, single-shot editing, and measuring; ImageMagick ("convert") for batch processing and a few other operations like joining and annotating images; and either C (with my own libraries) or python (with Pim for I/O, numpy for math) for more complicated processing, such as color correction and classification.  (I used to do these all in C, but I am increasingly switching to python for its native list/set/dict facilities.)

All the best, --stolfi
