I've tested the lasexample_add_rgb.cpp and it seams to fail to color the
las.

https://github.com/LAStools/LAStools/blob/master/LASlib/
example/lasexample_add_rgb.cpp

I'm using the test.laz here https://github.com/LAStools/
LAStools/blob/master/data/test.laz

I added

  //re-test
  LASreadOpener lasreadopener2;
  lasreadopener2.set_file_name(lasreadopener.get_file_name());
  lasreader = lasreadopener2.open();

  for(int i = 0; i < 5 && lasreader->read_point(); i++)
  {
      LASpoint *p = &lasreader->point;
      std::cout << "Color: ";
      for(int c = 0; c < 4; c++)
          std::cout << p->rgb[c] << " ";
      std::cout << std::endl;
  }

  lasreader->close();
  delete lasreader;

At the end to test right away and I get Color: 0 0 0 0

Same if I open the laz in CloudCompare. It identifies correctly as a rgb
las cloud (type 3) but the color is empty.

To be fair I'm still using the laslib repository version of Sept.2016, but
I think I never got the example to work and I found another way to do what
I wanted at the time.

I also have the same issue if I run las2las from LAStools
..\LAStools\bin\las2las -i my.laz -o myc.laz -set_RGB 100 0 0 -point_type 3

Am I the only one having this issue? Any hints on what might be causing
this?

Cheers,

Pol
