Delmic HDF5#
RosettaScIO can only read hyperspectral cathodoluminescence .h5 datasets from Delmic. The file reading will be implemented step by step for the various Delmic data formats.
Note
To read the cathodoluminescence .h5 datasets in HyperSpy, use the
reader argument to define the correct file plugin as the .h5
extension is not unique to this reader:
>>> import hyperspy.api as hs
>>> hs.load("filename.h5", reader="Delmic")
API functions#
- rsciio.delmic.file_reader(filename, lazy=False)#
Read a Delmic hdf5 hyperspectral image.
- Parameters:
- filename
str,pathlib.Path Filename of the file to read or corresponding pathlib.Path.
- lazybool, default=False
Whether to open the file lazily or not. The file will stay open until closed in
compute()or closed manually.get_file_handle()can be used to access the file handler and close it manually.
- filename
- Returns:
listofdictList of dictionaries containing the following fields:
‘data’ – multidimensional
numpy.ndarrayordask.array.Array‘axes’ – list of dictionaries describing the axes containing the fields ‘name’, ‘units’, ‘index_in_array’, and either ‘size’, ‘offset’, and ‘scale’ or a numpy array ‘axis’ containing the full axes vector
‘metadata’ – dictionary containing the parsed metadata
‘original_metadata’ – dictionary containing the full metadata tree from the input file
When the file contains several datasets, each dataset will be loaded as separate dictionary.
