HTML/JavaScript Image Processing SDK Libraries

LEADTOOLS includes JavaScript libraries that perform client-side image-processing within cross-platform, zero-footprint, HTML/JavaScript applications. They can be used stand-alone or Integrates with the LEADTOOLS HTML5/JavaScript Image Viewer Control, which is based on the HTML5 <canvas> tag, to add highly responsive, touch-enabled image processing to applications. The functions utilize JavaScript Web Workers for fast, multithreaded performance. By processing image data on the client, developers can provide a better user experience with faster and more responsive applications that do not require external server calls.
