pylas.compression module¶

The functions related to the LAZ format (compressed LAS) Lazperf is made optional by catching the ModuleNotFoundError, and raising an exception when compression/decompression is actually needed

There are also functions to use Laszip (meant to be used as a fallback)

class pylas.compression.LasZipProcess(action, stdin=-1, stdout=-1)[source]¶

Bases: object

class Actions[source]¶

Bases: enum.Enum

An enumeration.
