Usage Syntax: do_dcs(data, band1, band2, band3 [, ignore = VAL] [, sample = VAL] [, variance = VAL]) 'data' - a multiband numeric array of greater than three bands 'band1 - band3' - the red, green and blue bands in the dcs calculation 'ignore' an optional null value of the data, default = -32768 'sample' an optional color sample array 'variance' an optional color variance specification, default = 50 If no bands are specified an 8-7-5 stretch will be attempted.
