laspy.compression module¶
LazBackend¶
- class laspy.compression.LazBackend(value)[source]¶
Bases:
ILazBackend
,Enum
Supported backends for reading and writing LAS/LAZ
- LazrsParallel = 0¶
lazrs in multi-thread mode
- Lazrs = 1¶
lazrs in single-thread mode
- Laszip = 2¶
laszip backend
- classmethod detect_available() Tuple[LazBackend, ...] [source]¶
Returns a tuple containing the available backends in the current python environment
DecompressionSelection¶
- class laspy.compression.DecompressionSelection(value)[source]¶
Bases:
IntFlag
Holds which fields to decompress or not.
Only used for files with version >= 1.4 && point format id >= 6.
Ignored on other cases.
Each flag in the enum has a corresponding
decompress_$name
andskip_$name
methods to easily create a selection.>>> import laspy >>> # Creating a selection that decompresses the base + z field >>> selection = laspy.DecompressionSelection.base().decompress_z() >>> selection.is_set(laspy.DecompressionSelection.Z) True >>> selection.is_set(laspy.DecompressionSelection.INTENSITY) False
>>> # Creating a selection that decompresses all fields but the intensity >>> selection = laspy.DecompressionSelection.all().skip_intensity() >>> selection.is_set(laspy.DecompressionSelection.INTENSITY) False >>> selection.is_set(laspy.DecompressionSelection.Z) True
New in version 2.4.
