Demo Applications that Include HTML5/JavaScript Image Viewer

HTML5/JavaScript Viewer

Uses HTML5 and JavaScript to demonstrate features of the LEADTOOLS image viewer. Features include:

  • Load an image from url
  • Rotate
  • Zoom
  • Flip horizontally and vertically

HTML5/JavaScript Thumbnail and Bookmark

Uses HTML5 and JavaScript to demonstrate our thumbnail viewer to navigate pages of an image or document. The thumbnail viewer will display a small thumbnail image of all pages found in a document.

HTML5/JavaScript Document Viewer

Demonstrates the LEADTOOLS Document Viewer in an HTML5/JavaScript application. The Document Viewer can be used to view raster, text, and document formats, making it ideal for Enterprise Content Management (ECM), document retrieval, and document normalization solutions.

  • Load a document from local disk and url
  • Draw annotations on the document
  • Use thumbnail viewer for page selection
  • View any bookmarks that have been included in the document
  • Interactive zooming/panning
  • Print annotated documents

HTML5/JavaScript LEADVIEW

LEAD has packaged the LEADTOOLS Document Viewer web application and service into the LEADVIEW API component. It requires as little as three lines of code to plug the LEADVIEW API into any JavaScript application. The component is highly customizable and supports all the features of the existing low-level Document Viewer, including viewing and converting hundreds of file formats and more than 30 annotation and markup objects. Users can easily create themes for the UI or use the predefined dark or light themes. With a settings dialog or JSON file, the entire ReactJS UI can be customized by each end-user or administratively locked down at a server level.

HTML5/JavaScript Medical Web Viewer Framework

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.

Note: If you have your own test images that you would like to upload into the application, contact support@leadtools.com to have a private user profile created.

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.

  • Load a pre-loaded image
  • Draw annotations
  • Export image
