LEADTOOLS SDKs include flexible and time-tested document and image annotation technology for
.NET (C# & VB, Core, Xamarin, UWP), C/C++, iOS, macOS, Linux, Java, and web developers. LEADTOOLS
Annotations include a clean and diverse collection of markup objects and collaborative
tools designed to impart visual metadata to digital images and documents which enhance
user experience, productivity, and security. In addition to its award-winning annotation
technology, LEADTOOLS also supports specialized document and medical
annotations for industry standard formats, including PDF and DICOM.
Comprehensive multi-thread support for maximum performance
32 and 64-bit binaries for document and image annotation development
Storage of Annotations
LEADTOOLS annotations can be stored as an external annotation file, XML, private DICOM data elements, or within a TIFF file as LEAD or Wang annotation tags. Alternatively, annotations can become a permanent part of the image data or exported as SVG or EMF.
The simplicity of using LEADTOOLS annotations is extended to both the developer and the end-user. With very little code, the developer can create a fully automated, dynamic, and feature-packed annotation application which is also easy to operate by the end-user. Automation features include mouse event handling, cursors, toolbars, right-click context menus, and instant text editing.
With the LEADTOOLS Image Annotation Customizable Features, developers can create new annotation types, change the context menus and toolbars, and localize the dialog strings. End-users can rotate, calibrate, and change virtually any visual setting of the annotations on the screen.
Confidence and Security
Enhanced redaction objects hide and encrypt confidential parts of images even in non-LEADTOOLS viewers. When combined with annotation security, these redact objects provide a means of granting user-level access to view redacted areas of an image.
With LEADTOOLS Document and Image Annotation Technology, you can:
Implement annotation security for each and every object
Implement hyperlinks for every object; popular uses for hyperlinks include user-defined messages, run an application, and jumps to web pages
Save to file, memory, database, and clipboard
Perform the following operations on a single object or group of objects:

When it comes to change, the desire for efficiency is surely at or near the top of the list of reasons. Some processes and industries are harder to change, especially those that have been around for a long time. Court systems in many countries are one of the oldest and most well established processes to ensure all-around fairness, even if it must sacrifice expediency. Thankfully, the legal industry has taken major strides towards adapting to the digital age with the evolution of eDiscovery and document imaging.
Demo Applications that Include Annotation and Markup
Uses LEADTOOLS annotations and image-markup technology to add stamps, sticky notes, rulers, and various other image markup devices to an annotation layer of the image without changing the original image data.
A zero-footprint Medical viewer with light and dark themes to display DICOM images (pixel data) with window level, density removal, offset, scale, zoom, stack, annotation/markup, and multi-touch support for phone, tablet, and desktop.
It demonstrates zero-footprint 3D volume rendering of multiple volume types including VRT, MIP, MPR, and SSD in the Medical Web Viewer. The viewer does not require browser plugins, desktop utilities, or remote desktop clients and features low resolution and caching options for faster rendering and loading.
