In my previous post, "Solution to 4 Common First-world Problems – Convert and Merge to PDF," I implemented a solution to convert images of documents to text-searchable PDF files. The source images were produced from a document scanner and the camera on my phone. Since that post, I have received some questions on how to improve the human readability of the PDFs that were originally camera images.

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.

Below are links to recent code tip posts from our support department, as well as links to the homepage to the respective framework:

The latest update of LEADTOOLS V19 includes an MVC project using the LEADTOOLS DocumentViewer. Additionally, the services have been refactored so that the services configuration part of this paper is out of date and no longer applies. However, we have decided to continue to make this paper available because there is useful information on configuring CORS in IIS that applies to many different applications.

If you have any questions about how to use the LEADTOOLS DocumentViewer in an MVC application, please contact support@LEADTOOLS.com.
