Title:
nona segfaults with PNG and TIFF output
Status in Hugin - Panorama
Hi Bruno,
during testing I found some more bugs in the alpha channel handling, which only
occurs in some special cases. Nevertheless I tried to fix them. This requires a
touch up of some more code in changeset 13f7aeff8000
Could you please test that I did not break something what already worked?
Ok, grafted to 2015.0 branch.
2014.0 is using an internal vigra (very old version). So you did not see
the bug. Pablos old implementation does not work with the newer vigra
version. So Hugin is now using slightly modified impexalpha.hxx from
vigra directly (written by Chris Spiel).

Thanks, that works.
The current 2015.0 branch (dc7eb38fe1d5) patched with 5f45958ae420 now
renders TIFF without crashing.
(this is a 2015.0 bug. 2014.0 is fine, I even rebuilt it to be sure
there is no problem with the build environment. All this is with the
same vigra impex 1.10.0 library)

I can't reproduce the issue. It works for be.
Nevertheless I have an idea. Please test if changeset 5f45958ae420 fixes your
issue. If so we need to graft the changeset to 2015.0 branch.
