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.

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.
