PCL-LZF 24-bit RGB image format reader.
The main advantage of using the PCL-LZF image I/O routines is a very good file size versus I/O speed ratio. Tests performed using LZF, Snappy, ZIP, GZ2, BZIP2, as well as PNG, JPEG, and TIFF compression have shown that the internal PCL LZF methods provide the best score for the types of applications PCL is suited for.

Read the data stored in a PCLZF RGB file and convert it to a pcl::PointCloud type.
Note that, unless massively multithreaded, this will likely not result in a significant speedup and may even slow performance.

| virtual bool pcl::io::LZFRGB24ImageReader::readParameters | ( | std::istream & | is | ) | [virtual] |
Read camera parameters from a given stream and store them internally.
The parameters will be read from the <rgb> ... </rgb> tag.
Reimplemented from pcl::io::LZFImageReader.
