Hello,

I think David's hidden suggestion is, 'you better write it yourself'.

Your question does raise an important issue. It seems like a common issue,
too. There are ten gazillion 'standard' formats for data as produced by
different companies. Your example, ACR/NEMA, is just one. I have been
wrestling with IPLAB image formats (an complex of binary header, binary data,
and PICT vector overlays) and the NOAA raster charts (ASCII header and
run-length compressed binary data.), neither of which have I fully figured
out. More recently, I have been working on code to read the output logs
from SEABIRD CTD instruments. David has a recent example of reading 12bit
images stored in a 16bit format or some such thing. While these images may
be 'standards' for the commercial outfit that produces them, they are
certainly not universal, like TIFF, JPEG, ...

It is a shame there isn't a public repository of IDL code to read/write these
obscure but 'standard' formats.

Good luck!

Ben
