Hi,
I think there is a bug in libLAS 1.2.1 when retrieving point color
by random access (green and blue are interchanged), reader12.cpp,
line 334 ff:
detail::read_n(red, m_ifs, sizeof(uint16_t)); detail::read_n(blue,
m_ifs, sizeof(uint16_t)); detail::read_n(green, m_ifs,
sizeof(uint16_t));
I think this should read as
detail::read_n(red, m_ifs, sizeof(uint16_t)); detail::read_n(green,
m_ifs, sizeof(uint16_t)); detail::read_n(blue, m_ifs,
sizeof(uint16_t));
The same applies for lines 347 ff.
Volker,
I have confirmed this is fixed in libLAS 1.6.0b4 (we no longer read
fields this way either).
If you are interested, I could give you Mercurial push access if you
feel the need to continue to maintain a 1.2.x branch of libLAS. I do
not have the resources to keep applying patches there, but I can
understand if others would like to keep it alive for the time being.

Howard,
although my time is limited too, I would agree to maintain the 1.2.x
branch as long as SAGA GIS (and LIS) is using this version.
