ptohalve - Man Page

ptohalve [options] --output halved.pto project.pto

 Options:
  -o | --output     Filename of scaled project (can be the the same as the input)
  -h | --help       Outputs help documentation

ptohalve takes a hugin .pto project and halves all pixel dimensions.  It will fail if any photos have non-even pixel dimensions. If it succeeds you will need to rescale the photos to match:

  mogrify -geometry 50% *.JPG

Note, this tool is useful in conjunction with the ptodouble tool which performs the opposite transform.
