Are you using 'pdal translate' or 'pdal pipeline' here? 'pdal translate'
is going to ignore any reader and writer options in the pipeline and
take those from your command line.


The following pipeline works for me (the offset/scale on my new foo.las
file matches my options) by issuing 'pdal pipeline offset.json':
