public DecoderResult decode(boolean[][] image)
                     throws FormatException,
                            ChecksumException
```
    Convenience method that can decode a Data Matrix Code represented as a 2D array of booleans. "true" is taken to mean a black module.
    
    Parameters:
    
    image - booleans representing white/black Data Matrix Code modules
    
    Returns:
    
    text and bytes encoded within the Data Matrix Code
    
    Throws:
    
    FormatException - if the Data Matrix Code cannot be decoded
    
    ChecksumException - if error correction fails
  - decode

public DecoderResult decode(BitMatrix bits)
                     throws FormatException,
                            ChecksumException
```
    Decodes a Data Matrix Code represented as a BitMatrix. A 1 or "true" is taken to mean a black module.
    
    Parameters:
    
    bits - booleans representing white/black Data Matrix Code modules
    
    Returns:
    
    text and bytes encoded within the Data Matrix Code
    
    Throws:
    
    FormatException - if the Data Matrix Code cannot be decoded
    
    ChecksumException - if error correction fails
