Enums

  Data type of VLR extra bytes record
• LASReaderFlavor

Constants

• ATTRIBUTE_BASIC_FLAGS

  LAS flags for extended formats
• ATTRIBUTE_LOCAL_LAS_POSITION
  Custom position attribute for LAS positions in local space

Functions

• is_known_las_attribute
  Returns true if the given attribute is a known LAS point attribute. This function only checks the name of the known attributes and ignores the datatype, so a POSITION_3D attribute with datatype Vec3f32 is still considered to be a known LAS attribute (as pasture is able to perform type conversion).
• las_bounds_to_pasture_bounds
  Converts a las-rs Bounds type into a pasture-core bounding box (AABB<f64>)
• las_point_format_from_point_layout
  Returns the best matching LAS point format for the given PointLayout. This method tries to match as many attributes as possible in the given PointLayout to attributes that are supported by the LAS format (v1.4) natively. Attributes that do not have a corresponding LAS attribute are ignored. If no matching attributes are found, LAS point format 0 is returned, as it is the most basic format.
• offset_to_extra_bytes
  Returns the offset to the first extra byte in the given LAS point format. Returns None if the format has no extra bytes
• pasture_bounds_to_las_bounds
  Converts a pasture-core bounding box (AABB<f64>) into a las-rs Bounds type
• path_is_compressed_las_file
  Tries to determine whether the given path represents a compressed LAZ file or an uncompressed LAS file
• point_layout_from_las_metadata
  Returns a matching PointLayout for the given LASMetadata. This function is similar to point_layout_from_format, but also supports extra bytes if the given LASMetadata contains an Extra Bytes VLR. If it does not, but the point format in the LASMetadata indicates that extra bytes are present, the extra bytes will be included in the PointLayout as raw bytes
• point_layout_from_las_point_format
  Returns the default PointLayout for the given LAS point format. If exact_binary_representation is true, the layout mirrors the binary layout of the point records in the LAS format, as defined by the LAS specification. This means:
• write_las_bit_attributes
  Writes the given BitAttributes in LAS format to the given writer
