Leadtools.Codecs Namespace > RasterCodecs Class > EncodeAbic Method : EncodeAbic(Byte[],Int32,Int32,Int32,Boolean) Method



inputData
A byte array which contains the input data.
align
Number of bytes aligned for uncompresed 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.
Encodes the input raw data using the ABIC encoder.

Syntax

Visual Basic (Declaration) 
Public Overloads Function EncodeAbic( _
   ByVal inputData() As Byte, _
   ByVal align As Integer, _
   ByVal width As Integer, _
   ByVal height As Integer, _

Visual Basic (Usage)Copy Code
Dim instance As RasterCodecs
Dim inputData() As Byte
Dim align As Integer
Dim width As Integer

Dim value() As Byte
 
value = instance.EncodeAbic(inputData, align, width, height, biLevel)
C# 
public byte[] EncodeAbic( 
   byte[] inputData,
   int align,
   int width,
   int height,
   bool biLevel
)
C++/CLI 
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 uncompresed input data.
width

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.

Example

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

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.

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
