Hello all-
I have a question related to encoding. I'm using a seperate program which
takes either 16 bit or 8 bit (flat binary files) as inputs (they are raster
satellite imagery and the associated quality files), but can't handle both
at the same time. Problem is the quality and the image come in different
formats (quality- 8bit, image- 16bit). I need to switch the encoding on the

16/8 bit quantities represent? Are these files just a sequence of such
quantities, or is there meta information (i.e. image dimension)?

Does 'img files' indicate that these files are formatted according to a

I'm searching the wrong terms, but I did look. Is there any methods to do
this quickly? Ideally, the solution would involve reading in a list of
files and replacing the original with the new, 16 bit version, as I have
over 300 files to convert. I hope that's clear. Thanks in advance!
