Example

In This Topic
    ClassCodes Property (LasPointFilter)
    In This Topic
    Gets and sets the list of class codes to filter. Default value is null.
    Syntax
    public List<int> ClassCodes {get; set;}
    Public Property ClassCodes As List(Of Integer)
    Remarks
    If no list is set, points with any class code will be included.
    Example
    Search LAS Points
    // search all points

    // search all points
