classmethod Str2D.struct_array_from_bool_array(array: ndarray, char: str) → Str2D[source]

Create a structured array from a boolean array. This is useful when you have a boolean array and you want to convert it to a structured array with fields ‘char’ and ‘alpha’.

The ‘char’ field will be filled with the specified character where the boolean array is True and ‘ ‘ where the boolean array is False. The ‘alpha’ field will be 1 where the boolean array is True and 0 where the boolean array is False.

Parameters:

  • array (np.ndarray) – A 2D boolean array.

  • char (str) – The character to use when the boolean array is True.

Returns:

A structured array with fields ‘char’ and ‘alpha’ created from the input boolean array.
