freeman2img

Transforms one or several freeman chains into a pgm file by filling their interior areas.

The transformation can fill shapes with hole by using the freemanchain orientation. The interior is considered on the left according to a freeman chain move, i.e. a clockwise oriented contour represents a hole in the shape.

Usage: freeman2img [input] [output]

Allowed options are:

Positionals:
  1 TEXT:FILE REQUIRED                  Input freeman chain file name.
  2 TEXT:FILE                           the output file name.
 
 
Options:
  -h,--help                             Print this help message and exit
  -i,--input TEXT:FILE REQUIRED         Input freeman chain file name.
  -b,--border UINT                      add a border in the resulting image (used only in the automatic mode i.e when --space is not used.
  -o,--output TEXT=result.pgm           the output file name
  -s,--space INT x 4                    Define the space from its bounding box (lower and upper coordinates) else the space is automatically defined from the freemanchain bounding boxes.

Example:

$freeman2img ${DGtal}/tests/samples/contourS.fc sample.pgm

You will obtain such image:

Resulting image

Example with several contours:

The file located in $DGtal/examples/samples/contourS2.fc contains different contours with some ones corresponds to hole. We can apply the same conversion as the previous example:

$ freeman2img $DGtal/examples/samples/contourS2.fc  sample2.pgm

You will obtain such image:

Resulting image
