'Declaration Public Overloads Function EncodeAbic( _ ByVal inputData() As Byte, _ ByVal align As Integer, _ ByVal width As Integer, _ ByVal height As Integer, _ ByVal biLevel As Boolean _ ) As Byte()
'Usage Dim instance As RasterCodecs Dim inputData() As Byte Dim align As Integer Dim width As Integer Dim height As Integer Dim biLevel As Boolean Dim value() As Byte value = instance.EncodeAbic(inputData, align, width, height, biLevel)
public byte[] encodeAbic(byte[] inputData, int align, int width, int height, boolean biLevel)
Call this method to compress the input raw data to 1-bit bi-level or 4-bit grayscale ABIC data.
Use DecodeAbic(Byte[],Int32,Int32,Int32,Boolean) to decode ABIC data.
