wpx,wpy parameters

[SKUMUR]

I noticed that the polynomial parameters wpx and wpy and their reverses are not printed in the resulting KAP-files, but have the 'to do' status (in the code). Would be nice if someone could add these parameters to imgkap. I have the algoritms but I'm not a c-programmer and cannot contribute myself

Feel free to provide some pseudo code for the algorithms and I will eventually translate them into C.
