Nona has the same limitation as it uses the same underlying vigra
library for the image processing.

Title:
  nona crashes with std::bad_alloc when input has more than 2^31 pixels

Status in Hugin - Panorama Tools GUI:
  Won't Fix

Bug description:
  I would like to create cube faces for a 360° Panorama that is currently in equirectlinear projection with a size of 155.110 x 51.338 pixels (not full 180° height, top and bottom are cut away) - so a total pixel count of 7.963.037.180
  It's currently in png format, since most programs don't seem to know that with bigtif a tif can be bigger than 4gb.

  I like to use erect2cubic from the Panotools::Script cpan package. This creates a pto file which then needs to be called with nona:
  erect2cubic --erect=equirectlinear.tif --ptofile=cube.pto; nona -o prefix cube.pto

  This works perfectly when the total pixel count is smaller than 2^31.
  I am searching for a solution for bigger panoramas.

  enblend suffers from the same limitation, theres an quite old bug report in the enblend launchpad tracker
  https://bugs.launchpad.net/enblend/+bug/685105
  that sort of ended with the statement that panoramas with more than 2^31 are out of the scope of what enblend want's to achieve.
  Does this apply to nona too?

  Is there some hint any of the devs can give me how to work around this problem?
  In two of my previous panoramas I've stiched the 4 relevant faces seperatly directly with a linear projection, though I dislike this aproach because it's nearly impossible to make the 4 seams manually match. See:
