Charlotte, NC (January 9, 2023) -

LEAD is pleased to announce the release of another major update to LEADTOOLS Version 22. Highlighting this release is support for .NET 7, the ability to add eSignatures to documents and PDFs, significant recognition enhancements, as well as various notable updates to the Medical Web Viewer control including two brand new demos.

“As the document management industry continues to evolve digitally, the concern for security risks has never been more vital,” stated Moe Daher, Chairman and CEO of LEAD Technologies. “With the addition of multi-level eSignature support in our Document toolkit, developers working with LEADTOOLS are able to integrate a multitude of important document security features directly into their solutions with minimal changes to their code.”

.NET 7 Support

Microsoft announced the availability of .NET 7 in early November. As a long-time Microsoft partner, LEADTOOLS has supported .NET 7 since its release via Nugets. With this update, all the LEADTOOLS Recognition, Document, Imaging, and Multimedia libraries and binaries, as well as fully-sourced demos, are built with .NET 6+ as the target runtime.

New eSignature Support in the Document Viewer

Programmers leveraging the LEADTOOLS Document Viewer in their applications are able to view, convert, compose, edit, compare, and now also sign documents. With the NEW eSignature support, developers can easily add simple electronic signatures to documents and PDFs. For those looking to take verification and security further, this can be combined with LEAD’s certificate-based digital signature support for advanced electronic signatures that guarantee the document has not been manipulated.

Optimized QR Barcode Speed and Detection

The LEADTOOLS Barcode SDK received significant speed and detection optimizations for all QR Barcode types with major enhancements made to the detection of perspective distorted and skewed QR barcodes for all modules and versions.

Numerous OCR Enhancements

LEAD’s industry-leading, AI-Powered OCR SDK received notable recognition optimizations for: italic fonts, uppercase and lowercase letters, text line assembling and word construction, column detection, and baseline detection and text line segmentation.

New Medical Web Viewer Load Methods and Demos

The Medical Web Viewer now has new methods for loading DICOM files that use inputs defined by the DICOM Specification. This allows users to use the Medical Web Viewer Control to communicate with the front-end to the back-end using the DICOM standard and DICOMWeb. These load method inputs are Array DICOM JSON Instances (a standard DICOM JSON model described in PS3.18.F.2 of DICOM Specification), Instance Resource (described in PS3.18.10.6.3.3.3 of DICOM Specification), and Basic Structured Display as DICOM JSON.

With this update, LEAD also introduced two new demos:

  • The LEADTOOLS DICOM Watchdog Demo is an application and Windows Service that monitors the health of a LEADTOOLS DICOM Listening service. The DICOM Watchdog can be configured to automatically restart the LEADTOOLS DICOM Listening service if it is no longer processing DICOM Messages.
  • The LEADTOOLS HL7 Relay Demo is an HL7 Listener that can efficiently process large volumes of HL7 messages and quickly route the HL7 message to one or many locations.

Multimedia Updates

LEAD expanded support in the LEADTOOLS Multimedia Toolkit and demos for .NET 6+. Other updates include: added support in the MXF Demultiplexer for MXF Generic Container video streams with H.264 video format, a size limit increase to above 2GB of burning data in the DVDBurner, the ability for the MPEG-2 Transport and H.264 Decoders to handle video resolution changes while running, as well as added support for NULL output to our capture module, CUDA lossless format in the H.265 encoder, and H.265 encoded camera streams.

WebP Support

LEADTOOLS now includes read and write support for Web Picture (WebP) format.
