pano_modify: How to set projection parameters

Asked by Andreas Ulmer on 2018-04-06

Certain output projections have an additional projection parameters, e.g. Triplanar has one parameter called alpha in Hugin UI.

http://hugin.sourceforge.net/docs/nona/nona.txt labels it
# P"100 12" Parameters for tuning projection, number of parameters depends on projection

and it is stored in the p line of the pto

e.g. the P"120" in the line below.
p f18 w1024 h1024 v360 E3 R0 P"120" n"TIFF_m c:LZW r:CROP"

I'm trying to set this P value to a pto file using pano_modify (or another cmd line tool).

I did not find how to do this in the pano_modify man page, neither did I find a hint on the cpp
https://sourceforge.net/p/hugin/hugin/ci/default/tree/src/tools/pano_modify.cpp#l48

* is this probably just not doced?
* or not implemented?
* or can it be done with a different tool?

This was not yet coded/implemented (because there was no request for such a feature).

I implemented a new switch in the default branch of our repository: pano_modify --projection-parameter=120 project.pto to set the projection parameters.

Great! thanks a lot @tmodes.

Will there be a new build soon? Full Hugin build, or maybe just the tools?
Not sure I have the skills to build this myself.

For Ubuntu there are the nightlies: https://launchpad.net/~hugin/+archive/ubuntu/nightly/+packages
These contain already the new version.

For other OS there are no current public development versions (at least to my knowledge).

Can you help with this problem?
