Raw

Not released, target: 1.0.0

  • Added Support for Scaled Extra bytes

  • Added more type hints, which in combination to others changes should help IDEs provide better autocompletion.

  • Added pylas.LazBackend to be able to select the backend to use if many are installed

  • Changed support for the laszip backend to now use bindings to the laszip c++ API instead of using the laszip executable found in the PATH

  • Changed simplify EVLR Previously we had a EVLR class which was just a VLR subclass. Now EVLR are just VLR, kepts in a different list, and written as EVLRs if there are any.

  • Changed: VLRList now subclass list

  • Changed Header classes & Vlr The hierarchy of header classes (RawHeader1_1, RawHeader1_2, etc) is removed and now only one class exists LasHeader, where most of the fields that reader/writers care about are removed and field that user care about are kept and put in user-friendly classes.

    The vlrs are now also a part of the header (it simplifies synchronizing, the header, vlrs, point_format and extra bytes vlr)

  • Removed pylas merge

0.5.0b

  • Added write ('r') and append ('a') mode to pylas.open

  • Added ability to read a LAS/LAZ file chunk by chunk

  • Added ability to write as LAS/LAZ chunk by chunk

  • Added ability to append points to LAS/LAZ (LAZ only with lazrs)

  • Added SubFieldView class to handle LAS fields which are bit fields (e.g. return_number) in a more consistent way than was done.

  • Removed lazperf support for compression/decompression

0.4.3

  • Added maximum version to the lazrs optional dependency to 0.2.0.

0.4.2

  • Fixed writing LAZ file with EVLR when piping through laszip.exe

0.4.0

  • Added support for compressing & decompressing with laz-rs (supports parallel processing)
  • Added support for compressing using laszip.exe
  • Added Overflow & Underflow checks to the scaled x, y,z setters

0.3.4

  • Allow adding extra bytes to all las versions
  • Added rounding of x, y z coordinates when they are set

0.3.2

  • Changed the x, y, z offsets are not longer changed when new x,y or are set

0.3.0

  • Added supported_version function which returns the LAS version supported by pylas

  • Added a new PointFormat class

  • Added a merge_las function

  • Added mins & maxs properties to the header, they provide access to the x, y, z mins and maxs as numpy arrays

  • Fixed initialize the header.date to date.today()

0.2.0

  • Updated lazperf to handle lazperf exrabytes

  • Changed all pylas specific exception now inhereits the PylasError exception class
