pwspy.dataTypes.ERMetaData¶

class pwspy.dataTypes.ERMetaData(inheritedMetadata, numericalAperture, filePath=None)[source]¶

Bases: object

A class representing the extra information related to an ExtraReflectanceCube file. This can be useful as a object to keep track of a ExtraReflectanceCube without having to have the data from the file loaded into memory.

Parameters

inheritedMetadata (dict) – The metadata dictionary will often just be inherited information from one of the PwsCubes that was used to create this ER Cube. While this data can be useful it should be taken with a grain of salt. E.G. the metadata will contain an exposure field. In reality this ER Cube will have been created from pwsdtd.PwsCubes at a variety of exposures.
numericalAperture (float) – The numerical aperture that the PwsCubes used to generate this Extra reflection cube were imaged at.
filePath (Optional[str]) – The path to the file that this object is stored in.

classmethod dirName2Directory(directory, name)[source]¶

This is the inverse of directory2dirName

Return type: str

classmethod directory2dirName(path)[source]¶

Parameters: path (str) – The path to the file that stores an ExtraReflectanceCube object.
Returns: directory: The directory path, name: The name that the file was saved as.
Return type: A tuple containing

classmethod fromHdfDataset(d, filePath=None)[source]¶

Parameters: d (Dataset) – The h5py.Dataset to load the object from.
Return type: ERMetaData
Returns: A new instance of ERMetaData object

classmethod fromHdfFile(directory, name)[source]¶

Parameters

directory (str) – The directory the file is saved in.
name (str) – The name the object was saved as.

Return type

ERMetaData

Returns

A new instance of ERMetaData object

toHdfDataset(g)[source]¶

Parameters: g (Group) – The h5py.Group to save the new dataset into.
Return type: Group

classmethod validPath(path)[source]¶

Parameters: path (str) – The file path to the file to search for valid ExtraReflectance files.
Returns: validPath: True if the path is valid, directory: The directory the file is in, name: The name that the object was saved as.
Return type: A tuple containing

property idTag: str¶

A unique tag to identify this acquisition by.

Return type: str

property numericalAperture: float¶

The numerical aperture that this cube was imaged at.

Return type: float

property systemName: str¶

The name of the system that this image was acquired on.

Return type: str
