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.

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.
