Image Annotation and Markup SDK Technology

LEADTOOLS SDKs include flexible and time-tested 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.

Overview of LEADTOOLS Image Annotation SDK Technology

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.

LEADTOOLS annotations may also be exported as native PDF annotations in PDF documents with the LEADTOOLS Document Writers.

Ease of Use and Control

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 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:
    • Burn/Realize to bitmap data
    • Flip
    • Print
    • Reverse
    • Rotate
    • Scale
    • Shear
    • Translate
  • Display optional annotation captions
  • Add annotations to multi-page files

  • End-to-End eDiscovery with LEADTOOLS Document Imaging

    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

HTML5/JavaScript Annotations

Uses HTML5 and JavaScript to demonstrate our annotation and image-markup technology. Users may use the annotation toolbar at the bottom of the image 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.

Android Annotation App Android

The LEADTOOLS Annotations App can be used to annotate (mark-up) images without changing the image data.

iOS Annotation App iOS

The LEADTOOLS Annotations App can be used to annotate (mark-up) images without changing the image data.

macOS Annotation App OS X

The LEADTOOLS Annotations App can be used to annotate (mark-up) images without changing the image data.
