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. | Versions | Available Editions | | -------- | ------------------ | | 11.6.3000 | [JavaScript]({{ site.js_release_notes}}js-11.html#1163000-08252026){:target="_blank"} / [C++]({{ site.cpp_release_notes}}cpp-11.html#1163000-08202026){:target="_blank"} / [.NET]({{ site.dotnet_release_notes }}dotnet-11.html#1163000-08202026){:target="_blank"} / [Python]({{ site.python_release_notes}}python-11.html#1163000-08202026){:target="_blank"} / [Java]({{ site.java_release_notes}}java-11.html#1163000-08202026){:target="_blank"} | | 11.6.2100 | [JavaScript]({{ site.js_release_notes}}js-11.html#1162100-08182026){:target="_blank"} | | 11.6.2000 | [JavaScript]({{ site.js_release_notes}}js-11.html#1162000-08132026){:target="_blank"} / [Android]({{ site.android_release_notes}}android-11.html#1162000-08142026){:target="_blank"} / [iOS]({{ site.oc_release_notes }}ios-11.html#1162000-08142026){:target="_blank"} / [React Native]({{ site.react_native_release_notes }}react-native-11.html#1162000-08252026){:target="_blank"} | | 11.6.1000 | [C++]({{ site.cpp_release_notes}}cpp-11.html#1161000-07232026){:target="_blank"} / [.NET]({{ site.dotnet_release_notes }}dotnet-11.html#1161000-07232026){:target="_blank"} / [Python]({{ site.python_release_notes}}python-11.html#1161000-07232026){:target="_blank"} / [Java]({{ site.java_release_notes}}java-11.html#1161000-07232026){:target="_blank"} | ## 11.4 (02/05/2026) ### Highlights #### AI-Powered Barcode Detection and Decoding - **PDF417 Localization Model** – Introduces the `PDF417Localization` neural network model for improved detection of PDF417 barcodes, especially under challenging conditions. - **Code39/ITF Decoding Model** – Adds the `Code39ITFDecoder` model for enhanced decoding of Code 39 and ITF barcodes under blurred or low-resolution conditions. - **Deblur Models for 2D Barcodes** – Adds the `DataMatrixQRCodeDeblur` and `PDF417Deblur` models to provide more effective recovery from motion and focus blur for DataMatrix, QR Code, and PDF417 barcodes. #### ECI (Extended Channel Interpretation) Support - **ECI Information Return** – Adds support for retrieving Extended Channel Interpretation (ECI) data from barcodes. The new `CECISegment` class, along with the `GetECISegmentsCount()` and `GetECISegment()` methods in the `CBarcodeResultItem` and `CDecodedBarcodeElement` classes, enables access to character encoding information embedded in barcodes. - **ECI-Based Text Interpretation** – Adds support for interpreting ECI segments during barcode decoding, improving compatibility with international character sets. #### Performance Improvements - **On-Demand Model Loading** – Implements lazy loading for AI models, reducing initialization time by loading models only when first needed. - **Smart Model Selection** – Models are now loaded based on configured barcode formats, minimizing memory usage by excluding unused models. - **Improved Confidence Scoring** – Enhances confidence score calculation for results from neural network models, providing more accurate quality indicators. - **DPM Barcode Optimization** – Improves recognition rate for Direct Part Marking (DPM) barcodes commonly used in industrial and manufacturing environments. | Versions | Available Editions | | -------- | ------------------ | | 11.4.3000 | [C++]({{ site.cpp_release_notes}}cpp-11.html#1143000-06302026){:target="_blank"} / [.NET]({{ site.dotnet_release_notes }}dotnet-11.html#1143000-06302026){:target="_blank"} / [Python]({{ site.python_release_notes}}python-11.html#1143000-06302026){:target="_blank"} / [Java]({{ site.java_release_notes}}java-11.html#1143000-06302026){:target="_blank"} / [Android]({{ site.android_release_notes}}android-11.html#1143000-07072026){:target="_blank"} / [iOS]({{ site.oc_release_notes }}ios-11.html#1143000-07072026){:target="_blank"} / [JavaScript]({{ site.js_release_notes}}js-11.html#1143000-07022026){:target="_blank"}| | 11.4.2001 | [C++]({{ site.cpp_release_notes}}cpp-11.html#1142001-04172026){:target="_blank"} / [.NET]({{ site.dotnet_release_notes }}dotnet-11.html#1142001-04172026){:target="_blank"} / [Python]({{ site.python_release_notes}}python-11.html#1142001-04172026){:target="_blank"} / [Java]({{ site.java_release_notes}}java-11.html#1142001-04172026){:target="_blank"} / [JavaScript]({{ site.js_release_notes}}js-11.html#1142001-04242026){:target="_blank"} | | 11.4.2000 | [C++]({{ site.cpp_release_notes}}cpp-11.html#1142000-03182026){:target="_blank"} / [.NET]({{ site.dotnet_release_notes }}dotnet-11.html#1142000-03182026){:target="_blank"} / [Python]({{ site.python_release_notes}}python-11.html#1142000-03182026){:target="_blank"} / [Java]({{ site.java_release_notes}}java-11.html#1142000-03182026){:target="_blank"} / [JavaScript]({{ site.js_release_notes}}js-11.html#1142000-04212026){:target="_blank"} | | 11.4.1000 | [C++]({{ site.cpp_release_notes}}cpp-11.html#1141000-02052026){:target="_blank"} / [.NET]({{ site.dotnet_release_notes }}dotnet-11.html#1141000-02052026){:target="_blank"} / [Python]({{ site.python_release_notes}}python-11.html#1141000-02052026){:target="_blank"} / [Java]({{ site.java_release_notes}}java-11.html#1141000-02052026){:target="_blank"} / [Android]({{ site.android_release_notes}}android-11.html#1141000-02052026){:target="_blank"} / [iOS]({{ site.oc_release_notes }}ios-11.html#1141000-02052026){:target="_blank"} | ## 11.2 (10/14/2025) ### ✨ Key Highlights **AI-Powered Barcode Detection & Decoding** -
