This function returns information about a subsetted area of interest for a particular fieldlist.
Result = EOS_PT_REGIONINFO(pointID, regionID, level, fieldlist, size)
Returns SUCCEED (0) if successful and FAIL (–1) otherwise.
Point id (long).
Region id (long) returned by EOS_PT_DEFBOXREGION.
Point level (0-based long).
List of fields (sting) to extract.
A named variable that will contain the size in bytes (long) of subset period.
None
In this example, we get the size of the subsetted area of interest defined in EOS_PT_DEFBOXREGION from the Longitude and Latitude fields:
status = EOS_PT_REGIONINFO(pointID, regionID, 0, "Longitude, $
Latitude",size)
