All Implemented Interfaces:: Cloneable

public class TwoDCode extends Object implements Cloneable

Main class of the package and a wrapper for the integrated ZXing classes.

The class provides methods and constants that facilitate the integration of 2D codes into an existing application. It accepts settings in a type-safe form and validates them, catching any errors beforehand. This reduces the number of possible exceptions that can be thrown during code generation and helps to locate and handle them in a more differentiated way.

Usage:

Providing common settings such as code type (QR Code, DataMatrix, ...), the content, character set and quiet zone.
Providing type-specific settings for the 2D code type you want to create.
Check compatibility between the content and selected charset using canEncode().
Call buildSymbol() to generate the drawable code symbol.

Example:

     // Step 1: Common settings
     TwoDCode tdc = new TwoDCode();
     tdc.setType(TwoDType.QRCODE);
     tdc.setContent("Some content");
     tdc.setCharset(null); // include no ECI
     tdc.setQuietZoneSize(TwoDCode.ALL_QUIET_ZONES.get(TwoDType.QRCODE));

     // Step 2: Type-specific settings
     tdc.setQRCodeVersion(TwoDCode.QRCODE_VERSION_AUTO);
     tdc.setQRCodeErrCorr(1);

     // Step 3 and 4: Generate drawable symbol
     TwoDSymbol symbol = null;
     if (tdc.canEncode()) {
       try {
         symbol = tdc.buildSymbol();
       } catch (Exception ex) {
         // Handle the Exception
       }
     }

When generating GS1 DataMatrix or GS1 QR Code, the GS1Validator class from the "oned" package can be used to perform advanced content validation. See the setContent method description for more information.

Method Details
- setType
  
  public void setType(TwoDType codeType)
  
  Sets the type of the 2D code.
  
  Parameters:
  
  codeType - the type of the 2D code to set
  
  Throws:
  
  IllegalArgumentException - if the provided codeType is null
- setContent
  
  public void setContent(String content)
  Sets the content to be encoded in the 2D code.
  GS1 QR Code + GS1 DataMatrix: For GS1 formatted data, ASCII 29 must be used as FNC1 separator character where necessary. Note that the content should NOT include the leading FNC1, which indicates the GS1 data structure. It is recommended to validate the content using the GS1Validator class before setting. Example:
  import de.vwsoft.barcodelib4j.oned.BarcodeException; import de.vwsoft.barcodelib4j.oned.GS1Validator; String gs1 = "(01)01234567890128(15)191231"; String validated = null; try { validated = new GS1Validator(gs1, (char)29).getContent(); } catch (BarcodeException ex) { // Validation failed } if (validated != null) // ... use this method to set the validated value
  Parameters:
  
  content - the content to be encoded
  
  Throws:
  
  IllegalArgumentException - if the provided content is null or empty
  
  See Also:
  
  GS1Validator
- setCharset
  
  public void setCharset(Charset charset)
  
  Specifies the character set used to encode the content in the 2D code.
  If set to null (default), no character set information (ECI) is built into the code, and the default ISO 8859-1 character set is used. This is the default character set for all supported 2D types unless another character set is explicitly specified.
  GS1 QR Code + GS1 DataMatrix: For GS1 code types, specifying a character set is usually unnecessary since GS1 data typically consists only of ASCII characters, compatible with ISO 8859-1.
  
  Parameters:
  
  charset - the character set to be used for encoding the content, or null to indicate the default ISO 8859-1 charset with no ECI
- setQuietZoneSize
  
  public void setQuietZoneSize(int sizeInModules)
  
  Sets the size of the quiet zone for the 2D code.
  The quiet zone is the blank space around the 2D code that helps prevent interference or misreading of the code by surrounding elements. The size of the quiet zone is specified in modules. A module is the smallest single element in a 2D code, typically representing a single dot within the code.
  Standard quiet zones for all supported 2D codes are available in the ALL_QUIET_ZONES array.
  Note: For QR Codes, the specification defines a minimum quiet zone size of 4 modules. Although this minimum value is often used, it is not strictly adhered to and can vary depending on the application or implementation.
  
  Parameters:
  
  sizeInModules - the size of the quiet zone in modules
  
  Throws:
  
  IllegalArgumentException - if the specified size is negative
- setQRCodeVersion
  
  public void setQRCodeVersion(int version)
  
  Sets the version of the QR Code.
  The version determines the size and data capacity of the QR Code. Valid values range from 1 to 40 inclusive. A version of 1 means a 21x21 matrix and each subsequent version increases the matrix size by 4 modules. Version 40 represents a 177x177 matrix. Use QRCODE_VERSION_AUTO instead of a version number to automatically select the smallest version capable of encoding the content.
  Parameters:
  
  version - the version number of the QR Code (1 to 40) or QRCODE_VERSION_AUTO
  
  Throws:
  
  IllegalArgumentException - if the specified version is not within the valid range and does not match QRCODE_VERSION_AUTO
  
  See Also:
  
  QRCODE_SIZES
- setQRCodeErrCorr
  
  public void setQRCodeErrCorr(int errorCorrectionLevel)
  
  Sets the error correction level for QR Code.
  The error correction level specifies the amount of redundant data added to the symbol to enable error recovery. QR Codes support four levels of error correction: L (Low - ~7%), M (Medium - ~15%), Q (Quartile - ~25%), and H (High - ~30%). The higher the error correction level, the more redundancy is added, resulting in a higher resistance to errors, but also in a larger symbol size.
  The error correction level can be set to any value between 0 and 3 inclusive: 0 for "L", 1 for "M" (default), 2 for "Q", and 3 for "H".
  
  Parameters:
  
  errorCorrectionLevel - the error correction level to set for QR Code in the range 0-3
  
  Throws:
  
  IllegalArgumentException - if the specified error correction level is outside the valid range
- setDataMatrixSize
  
  public void setDataMatrixSize(int sizeIndex)
  
  Sets the size of the DataMatrix symbol.
  The size index [minus 1] represents the index of the DataMatrix symbol size in the DATAMATRIX_SIZES array. The value ranges from 1 to 30, inclusive, where 1 corresponds to the smallest size (10x10) and 30 corresponds to the largest size (144x144). Use DATAMATRIX_SIZE_AUTO instead of a size index to automatically select the smallest size capable of encoding the content.
  Note: The DataMatrix implementation allows the use of character sets other than ISO 8859-1 only when the size is set to DATAMATRIX_SIZE_AUTO.
  Parameters:
  
  sizeIndex - the index (1 to 30) specifying the size of the DataMatrix symbol or DATAMATRIX_SIZE_AUTO
  
  Throws:
  
  IllegalArgumentException - if the specified size index is not within the valid range and does not match DATAMATRIX_SIZE_AUTO
  
  See Also:
  
  DATAMATRIX_SIZES
- setDataMatrixShape
  
  public void setDataMatrixShape(int shape)
  Sets the shape of the DataMatrix symbol.
  Valid values are:
  
  DATAMATRIX_SHAPE_SQUARE: Square shape
  
  DATAMATRIX_SHAPE_RECTANGLE: Rectangular shape
  
  DATAMATRIX_SHAPE_AUTO: Automatically select the shape that best fits the content
  Parameters:
  
  shape - the shape of the DataMatrix symbol
  
  Throws:
  
  IllegalArgumentException - if the provided shape is not one of the valid constants
- setPDF417Size
  
  public void setPDF417Size(TwoDSize size)
  
  Sets the size of the PDF417 symbol.
  The PDF417 symbol size is specified in terms of the number of columns and rows. The number of columns can range from 1 to 30, and the number of rows can range from 3 to 90. If the width or height value is set to 0, the respective value is automatically selected based on the content to be encoded.
  
  Parameters:
  
  size - the size of the PDF417 symbol represented by a TwoDSize object
  
  Throws:
  
  IllegalArgumentException - if the provided size is null, or if the specified column or row have invalid values
- setPDF417ErrCorr
  
  public void setPDF417ErrCorr(int errorCorrectionLevel)
  
  Sets the error correction level for PDF417.
  The parameter specifies the amount of redundant data added to the symbol to enable error recovery. The higher the error correction level, the more redundancy is added, resulting in a higher resistance to errors, but also in a larger symbol size. PDF417 supports error correction levels from 0 to 8.
  
  Parameters:
  
  errorCorrectionLevel - the error correction level to set for PDF417 in the range 0-8
  
  Throws:
  
  IllegalArgumentException - if the specified error correction level is outside the valid range
- setAztecSize
  
  public void setAztecSize(int sizeIndex)
  Sets the size of the Aztec code symbol. The parameter can have the following values:
  
  AZTEC_SIZE_AUTO indicates that the smallest possible size capable of encoding the content is selected automatically (default).
  
  Negative numbers (-1, -2, -3, -4) represent compact Aztec codes. See: AZTEC_SIZES_COMPACT.
  
  Positive numbers (1, 2, ... 32) represent normal (non-compact) Aztec codes. See: AZTEC_SIZES_NORMAL.
  Parameters:
  
  sizeIndex - the index specifying the size of the Aztec code or AZTEC_SIZE_AUTO
  
  Throws:
  
  IllegalArgumentException - if the specified size index is not within the valid ranges and does not match AZTEC_SIZE_AUTO
- setAztecErrCorr
  
  public void setAztecErrCorr(int errorCorrectionLevel)
  
  Sets the error correction level for Aztec, specified in percent.
  The error correction level determines the amount of redundancy data added to the symbol for error detection and correction. Aztec symbols support error correction levels ranging from 5% to 95%. Higher error correction levels add more redundancy data, increasing the symbol's ability to withstand errors but also increasing its size.
  
  Parameters:
  
  errorCorrectionLevel - the error correction level for Aztec, specified in percent
  
  Throws:
  
  IllegalArgumentException - if the specified error correction level is outside the valid range
- canEncode
  
  public boolean canEncode()
  Checks if the specified charset can encode the given content.
  If no charset is specified (i.e., null), ISO 8859-1 is checked as this is the default charset used by all supported 2D code implementations.
  For several reasons, it is recommended to call this method before building the 2D code symbol:
  
  Some 2D code implementations (QR Code, Aztec) will generate the symbol even if the content cannot be encoded correctly with the specified charset, resulting in a 2D code that no longer contains the original information.
  
  In contrast, other implementations (DataMatrix, PDF417) will properly throw an exception if the content cannot be encoded. Such exceptions can be avoided by having this method perform the check in advance.
  Returns:
  
  true if the specified charset can encode the content, false otherwise.
- buildSymbol
  
  public TwoDSymbol buildSymbol() throws Exception
  
  Generates a drawable 2D symbol based on the provided properties.
  Any exceptions thrown by this method are forwarded exceptions caused by the internal call to ZXing's Writer#encode(). Since this method is implemented differently in the ZXing classes depending on the code type, it can throw different exceptions, even though only WriterException is declared by the Writer#encode() methods. Therefore, all exceptions are forwarded as a generalized java.lang.Exception.
  For example, the DataMatrixWriter and the PDF417Writer may throw different exceptions, even for the same reason, such as when non-encodable characters are detected in the content. While the first Writer throws the declared WriterException, the second may throw an IllegalArgumentException.
  The Writer implementations of the other two code types (QR Code and Aztec) do not throw an exception at all when encountering non-encodable characters, but instead encode the content with a loss of information due to incorrect character encoding. This underlines the importance of checking this first by calling canEncode().
  
  Returns:
  
  a TwoDSymbol object representing the generated 2D symbol
  
  Throws:
  
  Exception - if an error occurs during the symbol generation process
- getType
  
  public TwoDType getType()
  
  Returns the type of the 2D code.
  
  Returns:
  
  the type of the 2D code

- getCharset
  
  public Charset getCharset()
  
  Returns the character set used for encoding the content.
  
  Returns:
  
  the character set used for encoding the content
- getQuietZoneSize
  
  public int getQuietZoneSize()
