This is a bug. The points being read need to be rescaled before you write them.
I suspect in the compressed case, this is magically done for you.
Here's an inelegant stop gap. Please file a bug and I will try to have the
writer know when the data should be rescaled.
liblas::HeaderPtr hdr = liblas::HeaderPtr(new liblas::Header());
hdr->SetCompressed(compressed);
liblas::Writer writer( ofs, *hdr );
...
while( reader.ReadNextPoint() ) {
liblas::Point p = reader.GetPoint();
p.SetHeaderPtr(hdr);
++count;
writer.WritePoint( reader.GetPoint() );
}
