[Hugin-bug-hunters] [Bug 2053287] Re: sometimes there are black patches/corners in blended images
@Bruno Since last autumn (~September) main line vigra should support c++17, but any distribution release is of course likely to not have included that yet. But I guess it will fix itself in Fedora some time.

I'm not using msvc. This error is with fedora, but it looks like vigra in Ubuntu has already been patched to support c++17.

[Hugin-bug-hunters] [Bug 721136] Re: enblend creates an unexplainable black area.
The bug was what we had discussed on the hugin mailing list four years ago: https://groups.google.com/g/hugin-ptx/c/IgglWhsUCEQ/m/6bUu_YQpCAAJ tldr: one may generate a seam line such that pixels are included from an image that are out of bounds wrt that image. This fix only affects the blending stage. The seam generation and optimisation are off in more subtly ways, and harder to fix. -- You received this bug notification because you are a member of Hugin Bug Hunters, which is subscribed to Enblend. https://bugs.launchpad.net/bugs/721136 Title: enblend creates an unexplainable black area.

Thank you for merging and testing! The part that you omitted wasn't very important, but I am surprised that it causes issues with msvc (I had not tested that).

[Hugin-bug-hunters] [Bug 2053287] Re: sometimes there are black patches/corners in blended images
Yes, I replaced the `throw(PreconditionViolation)` with `noexcept(false)` in both vigra locations and now enblend builds. I'm using enblend cmake, as the autoconf stuff needed bootstrapping and I couldn't remember how to do it. Haven't tested the bugfix yet, I seem to remember I created test cases with several examples that all failed at some time. -- You received this bug notification because you are a member of Hugin Bug Hunters, which is subscribed to Enblend. https://bugs.launchpad.net/bugs/2053287 Title: sometimes there are black patches/corners in blended images Status in Enblend: Fix Committed Bug description: As has been known for a long time, enblend sometimes produces black patches in the corners of subimages.

@Bruno: Are you building with automake or with CMake? (On Ubuntu with CMake it works. But it seems they are providing a patched vigra library, where this offending line is missing.) @Lukas: I applied now most of your patches and pushed the changes to the repository.

Yes, that is weird.
