class createc.DAT_IMG(file_path=None, file_binary=None, file_name=None)

Read .dat file and generate meta data and images as numpy arrays.

There are two options for input:

option 1: one arg, i.e. the full path to the .dat file

option 2: two named args

  1. the binary content of the file together

  2. the file_name as a string

Parameters:

  • file_path (str) – the full path to the .dat file

  • file_binary (bin) – the binary content of the file together

  • file_name (str) – the file_name as a string

Returns:

dat_img – dat_file_object with meta data and image numpy arrays. Meta data is a dict, one can expand the dict at will. Images are a list of numpy arrays.

Return type:

DAT_IMG

__init__(file_path=None, file_binary=None, file_name=None)

Methods

Attributes

datetime

Return datetime objext of the file using the file name

nom_size

Return the nominal size of image in angstrom in namedtuple (x, y) assuming no pre-termination while scanning.

offset

Return offset relatvie to the whole range in angstrom in the format of namedtuple (x, y)

size
