Maybe it is right but looks to much deformed and looks like loosing some parts.
Just looks like.
I need engineering precision.
Will try, thx.
Can you explain g mic qt ….

If you cannot, ok thx anyway, you helped.
If engineering precision, what is the equation? If you can express exactly what you want to do, then you can create a displace map (actually, a pair of such). Then given a target bitmap, a source bitmap, and the displace map, the target bitmap is populated by fetching pixels in the source bitmap using X,Y offsets in the displace map. There is also a variant where the displace map are radius/angle offsets.
Then you create the displace maps using gradient, with which you can approximate about any function (which is going to be the inverse of the source->target function). This is something I am doing here.
If you need to go beyond this, you'll need to write you own C plugin, which is beyond my current competences.
