DESCRIPTION

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

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