Detailed Description

PCL-LZF 24-bit RGB image format writer.

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.
