Release Notes for Java Edition - 11.x

11.6.1000 (07/23/2026)

Highlights

Multimodal PDF Content Extraction

  • New PDF Reading Mode - Added PDFRM_MULTIMODAL to PDFReadingMode, now the default for PDFReadingParameter. It extracts vector graphics, text content, and embedded images from PDF files, enabling stronger barcode reading performance in multimodal PDF scenarios.
  • Performance Behavior Update - Compared with full-page raster rendering, PDFRM_MULTIMODAL usually improves speed by avoiding unnecessary rendering of irrelevant regions.

Multi-Threaded Barcode Decoding

  • Get results sooner with parallel processing - Barcode decoding now uses a breadth-first strategy that decomposes a single DBR Task into one Localization Work and one or more Decoding Works. This improves thread utilization and reduces the chance that a slow DeblurMode attempt blocks other faster decoding attempts, helping valid results come back sooner.

DataMatrix Color Inversion Detection

  • Handle normal and inverted DataMatrix more efficiently - Added AutoDetectColorInversion to automatically handle both normal and inverted DataMatrix barcodes. Instead of processing the whole image twice, the SDK applies dual-polarity handling only to localized DataMatrix regions, which makes processing faster in dual-polarity scenarios.

Barcode Layout Analysis

  • Decode dense grid barcodes more completely - Added LayoutAnalyzer to organize barcode locations into logical line or matrix layouts and infer unrecognized barcode regions when gaps exist, enabling workflows such as fast first-pass decoding, missing-region inference, and targeted second-pass decoding on dense N*M barcode layouts.

Cross-Version License Support

  • Use a single license across SDK versions - Full License 1.0 keys (starting with “f”) that are non-perpetual are no longer version-checked, so the same key can be used across SDK versions without reactivation.

New

Changed

  • Default PDFReadingMode in PDFReadingParameter constructor changed from PDFRM_RASTER to PDFRM_MULTIMODAL.

  • MaxParallelTasks now controls the total number of Work-level threads in the CVR thread pool. For DBR tasks, each Localization Work and Decoding Work occupies one thread slot.

  • setDeviceFriendlyName() now enforces parameter constraints: maximum 64 characters, allowed characters are letters (a-z, A-Z), digits (0-9), hyphen (-), underscore (_), and period (.), and must start and end with a letter or digit. Returns EC_PARAMETER_VALUE_INVALID if constraints are not met.

  • The Linux ARM64 minimum requirement is now glibc 2.27 (Ubuntu 18.04+, Debian 10+, and CentOS/RHEL 8+).

  • Removed the VC++ Redistributable runtime dependency for the JNI DLL on Windows (runtime linkage changed from MD to MT).

Fixed

  • Fixed a crash that could occur in AWS Lambda environments under certain conditions.

  • Fixed an issue in GS1-Databar AI 17 (YYMMDD) results where the month field could be missing a leading zero.
