ptovariable sets optimisation variable 'v' lines for a hugin .pto project. Usually this is a preparation for optimisation with autooptimiser or vig_optimize.

This performs the equivalent of the 'Positions, View and Barrel (y,p,r,v,b)' preset on the hugin Optimiser tab:

  ptovariable --positions --view --barrel project.pto
  autooptimiser -n -o project.pto project.pto

This is the equivalent of the 'Low dynamic range' preset on the hugin Exposure tab:

  ptovariable --vignetting --response --exposure project.pto
  vig_optimize -o project.pto project.pto

Additionally individual parameters can be set for particular photos:

  ptovariable -r 1 2 3 4 -p 4 project.pto
