Feature Description

LEADTOOLS document imaging SDKs offer .NET (C# & VB), C/C++, WinRT, iOS, macOS, Java, and web developers a variety of document image annotation options that can be integrated into your application to markup bitonal, grayscale, and color images. A distinct advantage of LEADTOOLS image annotations is that even though most document images are bitonal (1-bpp, black and white), color and multimedia image markups can still be added without changing the image data.

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.
