SizeL

Declaration: TMetaData.SizeL: integer;
The readonly property SizeL returns the number of data cells along the layer axis of the data cube. Please note that the layer axis might be subdivided into several spectral groups which can be evaluated and accessed by routines and properties such as CountSpectralGroups, FirstAvailableGroup or ObtainSpecRange.

Hint: In order to directly access the metadata of the currently loaded dataset you can use the pre-declared global variable MData.
