Copying Volumes

Another method of creating a volume is to simply copy the entire volume definition from an existing volume:

public  Volume   copy_volume_definition(
    Volume   existing_volume,
    nc_type  nc_data_type,
    BOOLEAN  signed_flag,
    Real     voxel_min,
    Real     voxel_max )

Creates and returns a new volume which has the same definition (sizes, voxel-to-world space transform, etc.), as an existing volume. If the argument nc_data_type is not NC_UNSPECIFIED, then the storage type of the new volume differs from the original and is specified by nc_data_type, signed_flag, voxel_min, and voxel_max. The voxel values are allocated but not initialized.
