## 11.6.1000 (07/23/2026)

### Highlights

#### Multimodal PDF Content Extraction

- **New PDF Reading Mode** - Added [`PDFRM_MULTIMODAL`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) to [`PDFReadingMode`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html), now the default for [`PDFReadingParameter`]({{ site.dcvb_java_api }}core/basic-classes/pdf-reading-parameter.html). 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`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) 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`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) 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`]({{ site.dcvb_java_api }}utility/layout-analyzer.html) 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

- Added [`PDFRM_MULTIMODAL`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) value to [`PDFReadingMode`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) enumeration for multimodal PDF content extraction.

- Added [`AutoDetectColorInversion`]({{ site.dcvb_parameters_reference }}barcode-format-specification/auto-detect-color-inversion.html) parameter for `BarcodeFormatSpecification` to support automatic color-inversion detection for DataMatrix barcodes.

- Added a new overload of [`captureMultiPages()`]({{ site.dcvb_java_api }}capture-vision-router/single-file-processing.html#capturemultipages) that accepts a [`FileFetcher`]({{ site.dcvb_java_api }}utility/file-fetcher.html) parameter for more flexible file input handling.

- Added [`LayoutAnalyzer`]({{ site.dcvb_java_api }}utility/layout-analyzer.html) class with [`analyze()`]({{ site.dcvb_java_api }}utility/layout-analyzer.html#analyze) static method for quadrilateral layout analysis.

- Added [`LayoutPattern`]({{ site.dcvb_java_api }}utility/enum-layout-pattern.html) enumeration with values `LP_UNKNOWN`, `LP_LINES`, and `LP_MATRIX`.

- Added [`LayoutElementSource`]({{ site.dcvb_java_api }}utility/enum-layout-element-source.html) enumeration with values `LES_NONE`, `LES_INPUT`, and `LES_INFERRED`.

- Added [`MeasureUnit`]({{ site.dcvb_java_api }}core/enum-measure-unit.html) enumeration with values `MU_PIXEL` and `MU_PERCENTAGE`.

- Added structures [`LayoutAxis`]({{ site.dcvb_java_api }}utility/layout-axis.html), [`LayoutAnalysisParameter`]({{ site.dcvb_java_api }}utility/layout-analysis-parameter.html), [`LayoutElement`]({{ site.dcvb_java_api }}utility/layout-element.html), and [`LayoutAnalysisResult`]({{ site.dcvb_java_api }}utility/layout-analysis-result.html) for layout analysis configuration and results.

- Added a new `GridBarcodeScanner` sample (with `sample_grid.png`) to demonstrate how to use [`LayoutAnalyzer`]({{ site.dcvb_java_api }}utility/layout-analyzer.html) for barcode grid layout detection and logical row/column mapping.

### Changed

- Default [`PDFReadingMode`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) in [`PDFReadingParameter`]({{ site.dcvb_java_api }}core/basic-classes/pdf-reading-parameter.html) constructor changed from [`PDFRM_RASTER`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html) to [`PDFRM_MULTIMODAL`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html).

- [`MaxParallelTasks`]({{ site.dcvb_parameters_reference }}capture-vision-template/max-parallel-tasks.html) 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()`]({{ site.dcvb_java_api }}license/license-manager.html#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`]({{ site.dcvb_java_api }}core/enum-error-code.html) 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.

### Deprecations

- Marked `PDFRM_VECTOR` as deprecated (covered by [`PDFRM_MULTIMODAL`]({{ site.dcvb_java_api }}core/enum-pdf-reading-mode.html)).
