RGBToCIELab Method

In This Topic

Converts integer RGB values to CIELab floating point results

Syntax

System.float[] RGBToCIELab( 
   System.int[] RGB
)

function RGBToCIELab( 
    RGB: System.Integerarray of
): System.array of Single;

function RGBToCIELab( 
   RGB : System.int[]
) : System.float[];

System.float[]* RGBToCIELab( 
   System.int[]* RGB
)

System.array<float>^ RGBToCIELab( 
   System.array<int>^ RGB
)

'Declaration
 
Function RGBToCIELab( _
   ByVal RGB() As System.Integer _
) As System.Single()

'Usage
 
Dim instance As IColourConverter
Dim RGB() As System.Integer
Dim value() As System.Single
 
value = instance.RGBToCIELab(RGB)

RGB: An array of 3 values. Although made as Int32 values for CLS complicance, the range should be confined to the ushort range (0 - 0xFFFF)

CIELab values in range 0-100.0 for L (first value) and -128.0 to +127.0 for a and b (second and theird values)

Requirements

Target Platforms: .NET CLR 4.8 or higher
