Fixed

• Bump lazrs to fix a bug that could happen in append mode (compatibility with older lazrs preserved, but without the fix)
• Bug in COPC where node with 0 points where not respected
• Fixed minimum values computed by laspy info
• The number of points by return is now correctly 64-bit and not 32-bit
• ScaledArrayView setitem/getitem whe index is in the form of [something, index]

Added

• Add copy method to LasHeader
• When the points given to the LasWriter.write_points are of type ScaleAwarePointRecord laspy now automatically rescale the points.
• ExtraBytesParams have a no_data attribute to specify which value is the no_data value
• min and max of extra bytes are now 'tracked' when writing, and their respective fields in the extra-bytes struct are populated
• laspy.open 'encoding_error' argument is also available to laspy.read (This argument can be used to how text encoding errors should be handled)

Fixed

• Fix compatibility with numpy 2.0
• Return None as CRS if WKT string is empty
  instead of having an exception from pyproj

Fixed

• Properly install laspy/cli/core.py file
• Don't install CLI tests as part of the package (tests/cli/*)
• Explicitly added 'rich' as a dependency of CLI feature

Fixed

• When trying to write more points than what is possible, now a
  proper error is raised.

Added

• CopcReader.open now accepts file-like objects.
• Add filter command to CLI

Fixed

• Fixed bug in laz backend handling in the CLI

Added

• Added optional CLI. It can be installed using the cli extra
  (pip install laspy[cli]). It has info, compress, decompress, convert
  and copc query commands.
• Added a prefer_wkt option to LasHeader.parse_crs
  (true by default) to prefer (or not) WKT VLR over Geotiff VLR
  in case both are present in the file.

Fixed

• laspy.open will now properly close the opened file
  if an exception is raised.
• Wavepackets's return_point_wave_location is now
  properly returned as as float32 and not an uint32.
• parse_crs properly checks that ProjectedCRSGeoKey/GeodeticCRSGeoKey
  is in range of EPSG code before using pyproj to parse it.
• Missing super.__init__() in CopcHierarchyVlr.
• Copc no longer include the hierarchy page twice
• A LasHeader with a custom creation_date/date will
  no longer be reset to date.today upon writing.

Fixed

• Removed spurious print in copc.py and compression.py

Added

• read_evlrs option (default true) to laspy.open, laspy.LasReader.__init__ and laspy.LasHeader.read_from
  Which allows to skip reading the EVLRs when opening a file. This can be useful when
  opening a LAS file from a non seekable source / where seeking is expensive as reading
  EVLRs requires seeking to the end of the file.
• Selective decompression feature that allows to select in a LAS 1.4 (fmt >= 6 && <= 10)
  which fields should be decompressed allowing to save time by decompressing only the fields
  that are needed. Works with LAZ and COPC files.

Changed

• The internal point reader is lazily created when the first point is actually read

Fixed

• LasAppender when input file's last chunk is complete
• Handle redundant CSs in GeoKeyDirectoryVlr

Changed

• EVLRs are now read during the file opening part.
• EVLRs are now part of the LasHeader class, but are still accesible via LasReader.evlrs or LasData.evlrs.

Fixed

• Fixed CRS parsing on fiels with both GeoKeyDirectoryVlr and WktCoordinateSystemVlr and the first one is empty
• LasHeader.parse_crs also looks for the CRS VLRs in the EVLRs of the file.
• Fixed LasHeader.generating_software and LasHeader.system_id being limited to 31 bytes instead of 32.
• Fixed laspy.convert to ensure the returng LasData.evlrs is a Vlrlist and no simply a list

2.2.0

Added

• Added support for querying COPC LAZ files via a new class CopcReader.
• Added new optional feature to support adding CRS / SRS to a LAS file from a pyproj.CRS as well as reading the CRS / SRS information from a LAS file to a pyproj.CRS.

Fixed

• Fixed support for stream / source that are not seekable.

Changed

• Support for Python3.6 removed.

Added

• Added new optional feature to support adding CRS / SRS to a LAS file from a pyproj.CRS as well as reading the CRS / SRS information from a LAS file to a pyproj.CRS.

Changed

• Support for Python3.6 removed.

• Fix function that parses geotiff VLRs
• Fix handling of points with 'unregistered' extra bytes (PR #158)

• Fix system_identifier reading by ignoring non ascii characters instead of erroring ,(issue #148, PR #149).
• Fix LasData.change_scaling method.
• Update minimum lazrs version which allows to:
  • Fix Appending in LAZ files.
  • Improve memory usage when reading/writing. (issue #152)

• Fix .min .max methods of array views
• Ship the tests as part of the source distribution

New major version of laspy with many improvements and also some breaking changes.

• Overhaul of the internals by essentially incorporating pylas into laspy, while the API to retrieve and set dimensions stayed the same, other parts changed and will require adaptation.
• Better LAZ support
  • Added support for writing LAZ
  • Changed decompression mechanism by using either laszip python bindings (and not laszip-cli) or lazrs
• Added ability to read and write LAS/LAS in stream / chunked mode.
• Changed laspy to support the reading and writing of LAS/LAZ data from and to file-objects and bytes
• Dropped support for python2.7, python3.6+ is supported.
