Java Library "Barcode-Lib4J"

Version 3.2.0 – Dec 23, 2025

BarExporter.java: Added setInlineSVG() method to generate SVG output suitable for embedding in HTML5 (omits XML declaration and xmlns attribute).
BarExporter.java: Replaced Area with ArrayList<Shape> for storage of Shape instances, significantly improving performance especially in headless Java environments.
BarExporter.java: BMP and PNG now stored as grayscale when possible (which is mostly the case as barcodes are usually black/white), reducing file size by ~67% for BMP and ~40% for PNG.
GS1Validator.java: Improved error message for AIs 00 to 02 to clearly state expected length.

Export to raster image formats: Added a defensive check for TIFF ImageWriter availability, and implemented proper resource cleanup for the ImageOutputStream along with explicit ImageWriter disposal.

Zero dependencies: Library is now completely self-contained with no external dependencies
PDF generation: Creates PDFs independently - OpenPDF is no longer required
EPS/PDF output: Reduced file sizes by ~13% using native rectangle commands instead of rectangular paths
Enum "BarcodeType": Added six "supports...()" methods to query barcode type properties without the need to create an instance
Enum "ImageTransform": Added "getRotationDegrees()" method to retrieve the rotation angle in degrees

GS1 Barcodes: Extended validation beyond the existing date/time checks for Application Identifiers 11 to 17 to now include format and plausibility validation for Application Identifiers 7003, 7006, and 8008.
OpenPDF Dependency: The library can now be compiled and used completely without OpenPDF - the dependency is fully optional, including at compile time.

Detailed BarcodeException messages for one-dimensional barcodes that provide more specific reasons why a barcode could not be created.
German localization for all exception messages.
Stricter validation of date values in the format YYMMDD for GS1 barcodes: The value must now not only consist of digits but also refer to a valid date.
