shapeGenerator

Generates shapes using DGtal library.

Usage: shapeGenerator [options] –shape <shapeName> –output <outputBasename>

Allowed options are:

-h [ --help ]                    display this message
-s [ --shape ] arg               Shape name
-l [ --list ]                    List all available shapes
-R [ --radius ] arg              Radius of the shape
-A [ --axis1 ] arg               Half big axis of the shape (ellipse)
-a [ --axis2 ] arg               Half small axis of the shape (ellipse)
-r [ --smallradius ] arg (=5)    Small radius of the shape
-v [ --varsmallradius ] arg (=5) Variable small radius of the shape
-k [ --k ] arg (=3)              Number of branches or corners the shape
--phi arg (=0)                   Phase of the shape (in radian)
-w [ --width ] arg (=10)         Width of the shape
-p [ --power ] arg (=2)          Power of the metric (double)
-o [ --output ] arg              Basename of the output file
--signature                      Display to the standard output the signature
                                 (normal, curvature) at each point of the
                                 specified shape contour (middle point of
                                 each contour linel)
-f [ --format ] arg (=pgm)       Output format:
                                   Bitmap {pgm, raw}
                                   Vector {svg} (+ {png,pdf} if libCairo
                                 installed)

You can list the potential shapes:

$ contourGenerator --list
2D Shapes:
       ball     Ball for the Euclidean metric.
        Required parameter(s): --radius [-R]
       square   square (no signature).
        Required parameter(s): --width [-w]
       lpball   Ball for the l_power metric (no signature).
        Required parameter(s): --radius [-R], --power [-p]
       flower   Flower with k petals with radius ranging from R+/-v.
        Required parameter(s): --radius [-R], --varsmallradius [-v], --k [-k], --phi
       ngon     Regular k-gon.
        Required parameter(s): --radius [-R], --k [-k], --phi
       accflower        Accelerated Flower with k petals.
        Required parameter(s): --radius [-R], --varsmallradius [-v], --k [-k], --phi
       ellipse  Ellipse.
        Required parameter(s): --axis1 [-A], --axis2 [-a], --phi

Example:

# generate an accflower shape with 6 petals of maximal radius 40 and small radius 10:
shapeGenerator -s accflower -R 40 -v 10 -k 6   -f pgm  -o test2

You should obtain such a resulting image:
