    GetTableIndex(Int64) Method
    In This Topic
    Obtains index in the table corresponding to Int64 input value.
    Syntax
    'Declaration
     
    Public Overloads Function GetTableIndex( _
       ByVal inputValue As Long _
    ) As UInteger
    'Usage
     
    Dim instance As ImGearFullLUT
    Dim inputValue As Long
    Dim value As UInteger
     
    value = instance.GetTableIndex(inputValue)
    public uint GetTableIndex( 
       long inputValue
    )
    public: uint GetTableIndex( 
       long inputValue
    ) 
    public:
    uint GetTableIndex( 
       int64 inputValue
    ) 

    Parameters

    inputValue
    LUT input value.

    Return Value

    Integer number.
    Remarks
    This method returns table index corresponding to input value. If LUT input is signed, and input value is negative, table index is calculated as 2's complement to number of table entries. Otherwise, table index is equal to input value.

    For example, if input depth is 12, and input value is -1, table index is 4096 - 1 = 4095.
