In This Topic

Obtains index in the table corresponding to Int64 input value.

Syntax

Visual Basic
C#
Managed Extensions for C++
C++/CLI

'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.
