Hallo,

I want to create a halo using the cli.

I have a picture which consists of a single matrix (i.e. the spectrum c is 1).

The values of the matrix either 0 or 1.

I want to compute a new matrix as follows:

The value at some entry [i,j] of the new matrix is the (euclidian)

distance between i,j and the closest 0-entry of the original matrix.

Best regards, Daniel
