Description

Export allows you to create a new LAS file with a subset of points that match a desired criteria. This method can also be used to rectify geo referencing errors in LAS files.
pTrackCancel is a reference to a cancel tracker object that can be used to monitor progress and/or cancel the process. This can be set to a NULL pointer ('Nothing' in VB) if desired.
FileIndex is the input index of the LAS file.
pFilter is point filter that allows you to select the desired points. If set to NULL, all the points in the input LAS file will be written to the output file.
newFileName is the name of the output LAS file.
pNewSpatialReference is the new spatial reference object.
bProject indicates whether the input point records are to be projected to the new spatial reference.
bDropVLRs indicates if the variable length records are written to the output las file or whether they are to be ignored.
