[ldd-img] Lossless as compression type #105

Closed rgdeen closed 4 years ago

rgdeen commented 4 years ago

Add "Lossless" as a valid for onboard_compression_type. For the heli I know it's lossless but don't know the specific compression type, so just generic Lossless.

updated. although "generic" Lossless is a little odd - could be anything.

@rgdeen new build here for testing: https://github.com/pds-data-dictionaries/ldd-img/tree/master/build/development/aba304de5aa01bf848324aefbe6ab706c975bfc4/1.14.0.0

I agree, but to some extent if it's lossless it really doesn't matter by definition, since the data got perfectly reconstructed. It matters for lossy so you know what kind of artifacts to expect.

And... thanks!
