[Bug 1750398] Re: align_image_stack fails to open EXR files

 

I fixed the error message in default branch. You now get a more verbose
warning instead.

align_image_stack was written for alignment of images directly from
camera. So no testing for exr was done. I've not found the bug until
now.

PS: In Hugins preferences there is an option to copy log messages to
clipboard > then all messages (even when the text if fast) are copied to
the clipboard and can be inspected afterwards.

Title:
  align_image_stack fails to open EXR files

Status in Hugin:
  New

Bug description:
  align_image_stack fails to open EXR files generated with darktable,
  the output is as follow:

  $ align_image_stack DSCF4117.exr DSCF4118.exr -p OUT.exr
  /build/hugin/src/hugin-2018.0.0/src/hugin_base/panodata/SrcPanoImage.cpp 346 Error opening file
  /build/hugin/src/hugin-2018.0.0/src/hugin_base/panodata/SrcPanoImage.cpp 346 Error opening file
  Written project file OUT.exr

  (an output file is generated, but it is only 12.9KB)

  I have tried every compression method (off, RLE, ZIP, ZIPS, PIZ,
  PXR24, B44, B44A) and the result is consistent. I'm using Arch Linux
  with hugin 2018 and openexr 2.2.0.
