PTOSORT(1)	      User Contributed Perl Documentation	    PTOSORT(1)

NAME
       ptosort - sort pto files with variable criteria

SYNOPSIS
       ptosort [options] infile.pto outfile.pto

	Options:
	 -p | --point order    Provide a sorting order for control points
	 -i | --image order    Provide a sorting order for images
	 -c | --clean yes/no   Switch removal of duplicate control points
			       on/off, default is on
	 -h | --help	       Show the full manpage

DESCRIPTION
       ptosort takes a pto file as input, sorts it and writes a sorted pto
       file as output. By default images are sorted according to their
       filename and control points are sorted by left image number, right
       image number and y pixel coordinate.

       The --point and --image command line options can be used to modify the
       sorting order. The order string should consist of a list letters
       separated by commas identifying the values to be taken for the
       comparison, e.g. for images y means yaw or r means roll. By default
       sorting for yaw (y), pitch (p), roll (r) and exposure (Eev) is fuzzy,
       i.e. values within an interval of 10 degress for yaw are considered to
       be the same. This is especially useful when sorting multirow panoramas.
       Appending a colon to the sort parameter forces strict sorting without
       fuzziness, while appending a tilde and a numerical value can be used to
       specify the fuzziness in terms of intervall width.

EXAMPLES
       ptosort --image n --point n,N,y in.pto out.pto
	    Sort the images by filename and the control points by left image
	    number, right image number and y pixel coordinate. This is
	    identical to the default behaviour without options.

       ptosort --image y in.pto out.pto
	    Sort images by yaw and control points using the default.

       ptosort --image y,p,Eev in.pto out.pto
	    Sort images in a multiraw panorama by position and exposure value.

       ptosort --image Eev:,y~5.5,p in.pto out.pto
	    Sort strict without fuzziness by exposure value, with a fuzziness
	    interval of 5.5 degree by yaw and by pitch.
