[Bug 989908] Re: black lines from graph-cut seam generator

 

Update...

I'm now down to a more manageable 2-frames panel, but still in fairly
high resolution (2 x 3200x4500 => 60000x6000 or 2 x 25MB => 50MB).
Problem still present.

I also tried the official 4.1 release on XP 32-bit. Problem present
there too, although the lines are in different locations.

Nothing fancy in the command line - actually extracted from Hugin's generated makefile:
enblend --compression=LZW -f59793x6071+1554+9345 -o ZZZTest4.tif -- ZZZTest40000.tif ZZZTest40001.tif

While downsizing, I didn't got the bug everytime. I'm under the
impression that it happens more often if the canvas is larger -  the
size of the sources images seems less important.

On the positive side, the final "writing output file" step is 1-2 orders
of magnitudes faster on 4.1/XP32 than on 4.0/Linux64 -  a very nice
improvement.

Comments?

Regards,

JMR

Title:
  black lines from graph-cut seam generator

Status in Enblend:
  New

Bug description:
  Using enblend 4.1-e378b04ea3b7 I'm seeing black seam lines when the
  graph-cut seam generator is used.  When I switch to use the nearest-
  feature-transform seam generator they go away.  It's a large stitch
  involving 13 images.  You can see the difference between the outputs
