[Liblas-devel] Reserved/Global encoding issue

[Ian Collins]

Hello,

 

With LAS v1.2, the 2 "reserved" bytes in the header are now used for
global encoding bits. If I open an LAS 1.2 file with global encoding of
1, this value will not be preserved if I write out the file. There is an
issue in the Header::read() method in header.cpp.

 

// 3. Reserved

// This data must always contain Zeros.

read_n(n2, m_ifs, sizeof(n2));

 

Should it also set the header right after the read?

 

m_header->SetReserved(n2);

 

Thanks,

Ian Collins
