New Imaging Technology for Java Programmers

Last week we touched briefly on the new Java libraries in our post about the latest Document Imaging features for Linux in LEADTOOLS. Today we’ll take a closer look at what the LEADTOOLS April update has for Java programmers as a whole, because it extends far beyond just Linux and document imaging.

The recent LEADTOOLS Version 19 update added far-reaching Java support for both Windows and Linux operating systems. These new, highly-requested imaging libraries for Java include functionality for nearly all markets and imaging technologies that LEADTOOLS is known for:

  • Viewers
  • Image formats
  • Compression
  • Image processing
  • Document Viewer and Converter
  • OCR
  • Barcode
  • Annotations

With Java comfortably holding one of the top spots in the world among programming languages, there are bound to be a huge number of developers and project managers ready and searching for ways to add imaging technology to their existing applications. This much is true from our conversations with customers looking for OCR, barcode, image conversion, and the like. We are happy to fill that need for the many Java development shops out there.

Also, Java developers working on new projects will be ready to create just about any application their clients might need on Linux and Windows. These new libraries closely resemble their .NET counterparts, which means if your goal is to port an existing application to the Java platform, you’ll have a fairly smooth transition.

Medical and Web Technology: Perfect Match with LEADTOOLS

At first glance, medical imaging technology and web may appear to be incompatible technologies because of non-standard medical-image bit depths and the huge amount of data associated with even just one DICOM dataset. However, as demonstrated with this last release, the engineers at LEAD Technologies continue to develop frameworks, technologies and algorithms that provide HTML5 developers tools to work with medical images over the wire, while still ensuring great UX for their users.

With input from numerous customer requests, structured display, templates and custom layouts have been added to the HTML5 Medical Viewer. With these features, the end-user can design custom display templates choosing from three ways to arrange series images: sequentially, DICOM instance number or custom alternative with JavaScript. Users can save the templates to a LEADTOOLS storage server as a DICOM structured display dataset; the LEADTOOLS Medical Viewer will use this to render series.

Besides adding new features, LEAD Technologies continues to refine the HTML5 Medical Viewer and related services with load, window-level, image processing and animation optimizations. Faster window-leveling opens the door to window-level even higher resolution images than were possible before. Other enhancements include better spy-glass support and support to load all types of images such as CT, MR, and MG.

At the core of many of these enhancements is the new multi-resolution and tiled image (MRTI) technology, which optimizes the delivery of large, extremely high-resolution images. MRTI intelligently serves a portion and resolution of the image based on the specific client request. This saves bandwidth, reduces memory requirements and improves the overall efficiency of the entire system.

To expand interoperability support with other PACS systems, LEAD Technologies now provides WADO-URI, WADO-WS, WADO-RS, STOW-RS and QIDO-R DICOMweb services that interface with LEADTOOLS PACS. These services conform to the latest version (2015c) of the DICOM PS3.18 specification. The source code for the services is available with LEADTOOLS PACS Imaging and LEADTOOLS Medical Imaging Suite products.

The healthcare industry remains an important vertical market for LEAD Technologies. We will continue to innovate, enhance, and extend LEADTOOLS to provide the highest quality and most complete DICOM and medical-imaging SDKs available. For more information, contact

LEADTOOLS for Linux – Document Features and Java

There are many reasons why Linux administrators are die-hard fans, and Linux will remain a viable option to host services for many years to come. Recognizing the many benefits of Linux, LEAD Technologies has released a major update to its LEADTOOLS for Linux offering, which is available in its LEADTOOLS Document and Medical product families. With these features now available, Linux developers and administrators can leverage LEAD Technologies’ years of experience to build and host modular, enterprise document services on secure and stable Linux servers.

The LEADTOOLS Document Viewer services can now be hosted on Linux as Java services. The LEADTOOLS Document Viewer includes rich document-viewing features such as text search, annotation, memory-efficient paging, inertial scrolling and vector display of files such as PDF, SVG, DOCX and DWG/DXF in HTML5 applications.

LEADTOOLS Document Writers create PDF, PDF/A, DOCX, RTF, TEXT and ALTOXML from SVG input. Other technologies within LEADTOOLS that create SVG, such as OCR, can leverage the Document Writers to save these document formats. This makes Linux the perfect platform to host enterprise OCR services to convert images to searchable and editable document formats.

LEADTOOLS Document Converter technology is now available for Linux to create powerful, automated document conversion, archival and delivery systems. Under the hood, LEADTOOLS Document Converter technology uses a combination of raster, OCR and Document Writers technologies to convert images and documents to PDF, PDF/A, DOCX, RTF, TEXT and SVG.

TWAIN remains the standard to acquire images from devices for Windows. Unfortunately, manufacturers have not taken up the mantle to provide these drivers for Linux. To work-around this limitation the Linux community has adopted the open-source SANE framework and has started creating SANE backends for many image capture devices. Recognizing that image capture is a requirement for complete document workflow, LEADTOOLS provides a Linux SANE frontend API to communicate with SANE backends.

Another major change to LEADTOOLS for Linux is a collection of new Java libraries. These Java libraries provide LEADTOOLS functionality to Linux with support for OCR, Documents library services, Document Writers, Document Converter, vector and document formats such as PDF and DOCX, and SANE scanning. Additionally, the libraries provide a common programming interface to develop applications for Windows and Linux.

With this major update, which is free to all LEADTOOLS customers with current a maintenance plan, developers can build robust, stable and secure enterprise document systems for Linux. For more information, contact

LEADTOOLS Document Viewer and Document Converter Professional Review

We absolutely love hearing from our customers regarding our products. In fact, one of the primary ways LEADTOOLS grows is through the direct feedback, suggestions and feature requests from our customers both with shipping products as well as those mulling through ideas during their evaluation. Today we’d like to introduce Carey Payette, an experienced programmer, mom of 3, black belt and conference speaker. She also writes for Code Project from time to time, which is why she is a part of our blog today.

She recently took LEADTOOLS for a spin and wrote about her experience with our Document Viewer and Document Converter technologies. Her article starts from scratch and shows how little effort it takes to view a raster image with searchable text in the Document Viewer. Then uses the Document Converter to convert the picture into a Microsoft Word DOCX file for editing.
