Last month we introduced LEADTOOLS Cloud Services, a brand-new product offering from LEADTOOLS, the World Leader in Imaging SDKs. We highlighted its OCR, Barcode, and Document Conversion features, and how to use the services in a Node.js application. In this post, we’ll explore a more applied scenario.

As part of the LEAD Technologies 25th anniversary, we are creating 25 projects in 25 days to celebrate LEAD's depth of features and ease of use. Today's project comes from Hadi.

If you've been keeping track, this is actually our 25th project and the last one in our #LEAD25 series. But don't be sad, we post examples like these to our blog and forums on a regular basis so keep in touch! If you missed any of them, take a look back at our series introduction where we've kept a running list as each project was posted.

Tonal range is an important attribute of an image, especially photographs, when trying to improve OCR results. Tonal range is the range of tones between the lightest and darkest areas of an image and is also known as contrast. An image with a wide range has both very dark (black) and very light (white) elements. An image with a narrow range is more limited in its tonal scope, which is usually in the mid-ranges (varying shades of grays).

Annotations are an important part of many document and medical imaging workflows. They allow users to mark up images with various shapes, notes, highlights, and redactions without having to permanently alter the image or document itself. One difficulty developers face is that annotations are not standardized. There are many standards, both open and proprietary, but not all of them play nicely with each other.

JavaScript frameworks. Love them, hate them, or die on a digital hill proclaiming the wonders of the newest and most cleverly named prefix to "JS," they all just boil down to something to help you build a web application. Thankfully, the LEADTOOLS HTML5/JavaScript Document Viewer can work with any of them, and we've had a recent wave of requests from customers wanting to integrate our viewer into the JavaScript framework they are using in their project.
