NAME
       ptovariable - prepare a pto project for typical optimisation tasks

SYNOPSIS
       ptovariable [options] project.pto

	Options:
	      --positions	   Optimise positions
	      --roll		   Optimise roll for all images except anchor if --positions not set
	      --pitch		   Optimise pitch for all images except anchor if --positions not set
	      --yaw		   Optimise yaw for all images except anchor if --positions not set
	      -r <num> <num> <..>  Optimise roll for specified images
	      -p <num> <num> <..>  Optimise pitch for specified images
	      -y <num> <num> <..>  Optimise yaw for specified images
	      --view		   Optimise angle of view
	      --barrel		   Optimise barrel distortion
	      --centre		   Optimise optical centre
	      --vignetting	   Optimise vignetting
	      --vignetting-centre  Optimise vignetting centre
	      --response	   Optimise camera response EMoR parameters
	      --exposure	   Optimise exposure (EV)
	      --white-balance	   Optimise colour balance
	 -o | --output OUTFILE	   Specify output file default is to overwrite input
	 -h | --help		   Outputs help documentation

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

EXAMPLES
       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
