rescaled_data= _fRescale(data, bitpix, bscale, bzero, data_min=, data_max=) Linearly rescale the values of input array DATA to fit into integers with BITPIX bits per value (i.e., `char', `short' or `long' for BITPIX being 8, 16 and 32 respectively). Arguments BSCALE and BZERO are optional and purely outputs passed by address. Their value will be set so that: DATA(i) = BZERO + BSCALE * RESCALED_DATA(i) where the equality may not be exact due to rounding errors. The difference is however the smallest possible, i.e., less than BSCALE / 2. Keywords DATA_MIN and DATA_MAX may be used to supply the maximum and minimum data values or to set brightness cutoffs. Originally from fitsRescale in the Yorick fits.i distrib. | |
