shapeGenerator

Generates shapes using DGtal library.

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

Allowed options are:

-h,--help                             Print this help message and exit
-l,--list                             List all available shapes
-s,--shape TEXT                       Shape name
-R,--radius FLOAT                     Radius of the shape
-A,--axis1 FLOAT                      Half big axis of the shape (ellipse)
-a,--axis2 FLOAT                      Half small axis of the shape (ellipse)
-r,--smallradius FLOAT=5              Small radius of the shape (default 5)
-v,--varsmallradius FLOAT=5           Variable small radius of the shape (default 5)
-k UINT=3                             Number of branches or corners the shape (default 3)
--phi FLOAT=0                         Phase of the shape (in radian, default 0.0)
-w,--width FLOAT=10                   Width of the shape (default 10.0)
-p,--power FLOAT=2                    Power of the metric (default 2.0)
-o,--output TEXT                      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 TEXT                      Output format:
                                          Bitmap {pgm, raw}
                                          Vector {svg} (+ {png,pdf} if libCairo installed) (default pgm)

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:
