[ptx] Some Hugin enhancement requests

[Pablo dAngelo]

Hi Mike,

Overall, my main goal is a stable hugin version that can be release as 0.5.

I will have to reduce the time I spend on programming hugin dramatically over the next few months. Given that I won't like to add a lot of new features (that will probably introduce new bugs) right now, but stabilized and remove the last few bigger errors (crashes etc.).

The only really new feature that I hope to get into, is the perspective corrected magnified
display of control points. Other features have to wait.

simply because there is no code in nona anymore that produces feathered blending. :)

Please show me where you have seen the feathering in the nona output...

Hmm, maybe, but don't count on it.

Hmm, some wrestling with the ugly internals of wxWindows.... hmm, low priority.
actually the whole thing needs to be replaced, because there is no checkbox list available on the mac version of wxWindows... but no time for that now.

Hmm, never tried or needed that so far. I think.. well. maybe a duplicate button in the next version, after 0.5

definately post 0.5.

it can be disabled by editing the registry/config file. maybe I'll move it to a separate window before 0.5

I had hoped that the people would just choose "high quality tiff" stitcher preset
and everything is fine.

Hmm, I've to add some more fields to the lens parameter files. However, I guess the values one enters there won't be very perfect.
Its much better to calibrate the lens once, save the values, and use them later on.
I'm not sure if that additional crop factor is really needed.

Well they all could be implemented, I just don't have the time to do it...

Sorry, but I really have to cut down the time I spend on hugin. Its just a bad time for new feature requests.

ciao
