just a 32bits array full of 1500. and 3000. as described previously
Does the endian-ness of the floats in the file match the endian-ness
of the processor the code is running on?
Also, in the NSCalibratedWhiteColorSpace, white is 1.0, black is 0.0,
and grays all lie in the normalized range 0.0 thru 1.0. So 1500 and
3000 are "whiter than white" and will undoubtedly be truncated to
white (1.0).
It's unclear to me what the "white" value is in your 1500 and 3000
values, but if 3000 is white, then you need to divide your raw data
by 3000 to get it into normalized range.
