The class TSpdcSet supports the management of spectral descriptor (SPDC) sets. You can load and save SPDC sets from/to the harddisk, or construct them from scratch. From the perspective of data structure the set of descriptors can be seen as a dynamic array of instances of the class TSpdc. This dynamic array can be accessed by the array property Spdc. You can manipulate this array by using the methods shown below:



Please note that there is a predeclared instance of the class TSpdcSet, called SPDCData, which is globally available throughout a script and which allows you to access the spectral descriptors currently loaded in Epina ImageLab and shown in the Spectral Descriptor Editor.
