EncodeAbic(byte[],int,int,int,bool) Method

Summary

Encodes the input raw data using the ABIC encoder.

Syntax

C++

Java

public byte[] EncodeAbic( 
   byte[] inputData, 
   int align, 
   int width, 
   int height, 
   bool biLevel 
)

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()

public byte[] encodeAbic(byte[] inputData, int align, int width, int height, boolean biLevel)

public: 
array<byte>^ EncodeAbic(  
   array<byte>^ inputData, 
   int align, 
   int width, 
   int height, 
   bool biLevel 
)

Parameters

inputData
A byte array which contains the input data.

align
Number of bytes aligned for uncompressed input data.

width
Image width, in pixels.

height
Image height, in pixels.

biLevel
true to indicate bi-level encoding, false to indicate 4-bit grayscale encoding.

Return Value

A byte array that contains the ABIC encoded data.

Remarks

Call this method to compress the input raw data to 1-bit bi-level or 4-bit grayscale ABIC data.

Use DecodeAbic to decode ABIC data.

Example

This example will load a file and encode as as ABIC. Decodes the data again before saving it to a destination file
