HTML5/JavaScript Image Processing SDK Libraries

Download

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.

"We started to work with LEADTOOLS to add very powerful OCR functionality to our product. LEADTOOLS has been very supportive and easy to work with during our development allowing us to create an even better product!"

Christian Berg

Founder and CEO

"We have been using LEADTOOLS since the development of our first product version of the dhs Image Database in 1994. We chose LEAD because all our requirements could be covered with one tool. The dhs Image Database has been used worldwide for over 25 years as a modular image management system in the QA and the laboratory area for archiving, recording, processing, anaylsis, and documentation. We started using LEADTOOLS for reading, writing, and visualizing the already extensive number of different image formats. We’ve also started to add in annotations throughout our time using LEADTOOLS we have never experienced any major issues. Their support team has always been informative and quick to help!"

Development Team

"We chose LEADTOOLS Imaging Pro Toolkit because we needed support for all standard image formats including PNG, BMP, and JPEG. Integrating LEADTOOLS within our multi-user viewer, ImageView Standard, has helped elevate our solution to it’s best-in-class status for financial institutions and Fortune 1000 companies."

Yojna Engineering Team

"We selected MiPACS as the anchor solution for Pacific Dental Services 1VU, our modern-day approach to dental image management. With 800+ offices across the US, an enterprise focused imaging solution was a must-have requirement. MiPACS integrates seamlessly with our Practice Management System EPIC, supports the sensor, panoramic and CBCT devices we want to use, and includes a HTML5 zero-footprint web viewer. It gave us confidence that MiPACS is built using the LEADTOOLS Medical Developer Toolkit. LEADTOOLS powers many enterprise applications and solutions, so we knew that MiPACS had a solid foundation backed by technology that would solve our current and future needs."
