Description

Returns a Las point enumerator to retrieve points from a LAS dataset with a constraint on the upper limit of the number of points.

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.

pFilter references a ILasPointFilter that defines the selection criteria for what points to read from the las files.

maxPointCount is the maximum number of points that is desired.

zFactor is used to convert the vertical units of the retrieved points (e.g., to convert feet to meters). The output point z values are multipled by the zFactor.
