[Hugin-bug-hunters] [Bug 1860256] [NEW] Stitched image has black patches
Public bug reported: Normally Hugin works fine for me, but my current image has black notches at the bottom when I stitch it. I tried tweaking the size and cropping, but the problem has happened four times and I can't get a successful stitch. It looks like two of the source images are getting partially blacked out in the stitch. I'm stitching 52 files, but I don't think I'm doing anything out of the ordinary. I've attached a screenshot of the preview (which looks correct), a screenshot of the output (since the full image is pretty large) showing the black notches, and the pto file.

[Hugin-bug-hunters] [Bug 1824267] [NEW] Could not stitch preview. Precondition violation!
Public bug reported: I was stitching images and everything was going fine with Panorama Preview, when suddenly I started getting error dialogs instead of a preview: Could not stitch preview. Error: Precondition violation! BasicImage::upperLeft(): image must have non-zero size. (/Users/niklas/development/release/hugin/mac/ExternalPrograms/repository/include/vigra/basicimage.hxx:928) One cause could be an invalid or missing image file. I tried reopening the file, upgrading from the 2016 version to 2019.0.0.a369cbe55179 (Mac), removing images and nothing helped. Comparing with a working file, I found a workaround. I edited my .pto file and changed line #3: p f2 w3000 h1 v23 E2.30282 R0 n"TIFF_m c:LZW r:CROP" I changed "h1" to "h261" and the project then worked fine. Changing back to "h1" repeatably caused the problem to happen. My guess is that Hugin doesn't like a horizontal size of 1 and this triggers the precondition violation. I don't know what specifically triggered this problem; I was clicking "center" and "fit" on Panorama Preview when things went bad. The symptoms are similar to bug 679273, but I was not using stereographic projection. There's probably not enough information here to fix the bug. I'm mainly filing this so the workaround will show up if anyone else encounters the problem. ** Affects: hugin Importance: Undecided Status: New -- You received this bug notification because you are a member of Hugin Bug Hunters, which is subscribed to Hugin. https://bugs.launchpad.net/bugs/1824267 Title: Could not stitch preview.

[Hugin-bug-hunters] [Bug 721136] Re: enblend creates an unexplainable black area.
I encountered this problem (a couple random gray squares in my stitched image) with Hugin 2016.2.0.be8da0221960. I tried the workaround in bug #1795269: add --primary-seam-generator=nft to the enblend parameters, and that made the problem go away. -- 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.
