6 ptomorph - Distort photos before stitching
7
9 ptomorph [options] project.pto
10
11 Options:
12 -h | --help Outputs help documentation
13 -j | --jobs numb Use that many jobs parallel if possible
14 -o | --output name Output .pto project name, defaults to 'morphed.pto'
15 -p | --polynomial num Uses a polynomial best fit, num is 'order' of polynomial
16 and must be 1, 2, 3, 4 or 5
17
19 ptomorph looks at control points in a Hugin PTO panorama project and
20 creates a new set of photos that are distorted such that these control
21 points line up perfectly. Distortion is a 'rubber-sheet' type morph.
22
23 A PTO project is created that references these distorted photos, this
24 project can then be stitched as normal.
25
26 Temporary distorted images are in PNG format with filenames based on
27 the prefix of the new PTO filename. i.e. this command:
28
29 ptomorph -o /path/to/morphed.pto project.pto
30
31 ..will produce the following files:
32
33 /path/to/morphed.pto
34 /path/to/morphed_0000.png
35 /path/to/morphed_0001.png
36 /path/to/morphed_0002.png
37 etc...
38
39 Control point positions are calculated using the 'pano_trafo' tool from
40 the Hugin project, the morphed photos are created with 'convert' from
41 the ImageMagick project.
42
43 By default the 'Shepards' distortion is used, if a polynomial is
44 specified then the ImageMagick 'Polynomial' distortion is used, see
45 <http://www.imagemagick.org/Usage/distorts/#polynomial> and
46 <http://www.imagemagick.org/Usage/distorts/#shepards>
47
48 Masks and cropping settings are not distorted, so projects with masks
49 that need lots of distortion may not work so well.
50
51 Note: Due to the way that the 'pano_trafo' process is spawned, it is
52 likely that this proof of concept tool doesn't currently work on
53 Windows.
