As you deduce I am more interested in the processing algorithm than the coding. There are too many poor results at the moment and I suspect there will be modifications to the method when I have more experience of its performance. For this reason I have not put it on a gimp site. I am happy for anyone to develop the plug-in further and improve the interface but there is not much point until the algorithm is unlikely to change. I have killed the spurious hidden image which was left over from the way of correcting the side absorptions.
