Title:
pano_trafo doesn't flush output, mixed use of C i/o and streams
Status in Hugin - Panorama Tools GUI:
Confirmed
Bug description:
Hi all!
I've had an issue with pano_trafo: The output of the transformed coordinates
wasn't flushed after each line, so I couldn't use it with a pipe on the output
end from a Python process; the output just wouldn't come. I noticed that the
source mixed C-style calls to fprintf() etc. with C++ stream i/o, which, if I
am not mistaken, is considered prone to malfunction. Replacing the C-style i/o
with stream i/o solved the problem for me.
At the same time I found it problematic to be limited to working on only one
image at a time, since I wanted to work on control points. I extended
pano_trafo to also work without the image number passed on the command line: If
it doesn't receive the image number on the command line, it expects input in
the form of triplets <image nr> <x> <y>
My hugin version is Pre-Release 2010.5.0.687a025dd22f, self-built on Kubuntu
10.10.
Find enclosed a patch which reflects my modifications; I hope I did it right ;-)
With regards
Kay
