Declaration: UpsampleSpectra (Mode: TUsMode; UsFact, SpecGroup: integer; FeedBack: boolean): integer;
Upsamples the spectra of all pixels (of all time slots) belonging to the spectral group SpecGroup. The parameter UsFact specifies the upsampling factor (valid range 2...4). The parameter Mode determines the type of interpolation used for the estimation of the inserted data points and can assume the following values:
usNone ... no interpolation, the inserted data points are zero
usSampleHold ... replication of the data values (results in a step function)
usLinInterpol ... linear interpolation

Setting the Feedback parameter to TRUE activates the ImageLab progress bar to provide visual feedback of the process.

The function returns the following error codes:

 0 ... everything is OK
-1 ... USFact is out of range
-2 ... invalid SpecGroup
