Hi

If I remember, there is a formula to trace a curve wich approximate a zig zag ing curve. They use it in finance and else.

That would be a nice feature.  I think . . .

Do you mean a curve that zigs and zags between points in a straight line?  It this will fix the economy, or have some usefulness for good images, cette une bonne idea!

Yes, this feature could be added to Curvemeister.  I would need to be convinced that it is actually useful in a practical sense.  Each of those corners will show up as banding in a normal image. 

Photoshop can do this, by the way, by clicking on the curve's pencil icon and then shift-clicking on the curve to define straight lines.  Here's a gradient, showing the banded effect from even a fairly mild set of straight lines.

Question....

Would this be a switchable option??  I kind of like the ability to set up a pretty sharp dog leg curve once in a while....

It does not remove or replace the curve it smoothes the curve. Dogleg or else.

Yes but if that is true, then I lose correction that I might just want a sharp bend in the curve for. 
I would be back to an average correction rather than my hard fought dog leg.  It might smooth the middle of the curve quite nicely but at the extreme ends I might just want a nice sharp bend.

Food for thought - another use would be when splitting the a and b channels, using separate curves on them.

In that case you just dont use it ;-)

True enough Jean...

The original question was would this be switchable....all that being said....
