Module py_img_algos.cspad_image_producer

This module gets from evt store the numpy array identified by key_in of full scale shape (4,8,185,388) or (185, 388, 2) for CSPAD or CSPAD2x2, respectively, and produces 2-d image numpy array, taking into account geometry calibration parameters specified by the path calib_dir. The output image array is saved in the evt store with unique name, specified by parameter key_out.

calib_dir

'' (empty)

string

key_in

cspad_array

string

keyword for input numpy array, shape=(4, 8, 185, 388) - for cspad or (185, 388, 2) - for cspad2x2

key_out

cspad_image

string

unique keyword for output 2-d image numpy array

print_bits

module verbosity:

  • =0 - print nothing
  • +1 - input pars (in __init__)
  • +2 - calibration parameters (in the 1st event)
  • +4 - configuration parameters (in the 1st event)
  • +8 - part of CSPAD array (in event)
  • +16 - output image shape (in event)

Module py_img_algos.image_save_in_file

This module gets from evt store 2-d image numpy array for specified unique name in key_in and saves it in the file with name given by parameter ofname. File extension defimes defines the output file format. Run and event numbers are added to the name of the output file. For example, for ofname = image.tiff files will be created with names image-r####-ev######.tiff, where symbols # stands for numbernumbers.
