Individuals and organizations often utilize various types of annotations to mark-up images and documents. But as digital collaboration grows, so does the need for defining and granting user and group level permissions to create, edit, and remove annotations. This blog walks through how to implement and set annotation roles and groups in a .NET 6 WinForms application using LEADTOOLS.

As we move further into the 21st century, the era of communication and social media continues to grow and evolve. Blogs, YouTube and other social media formats consume videos regularly. The ability to capture from these sources is mandatory.

While we can talk all day about how great LEADTOOLS is, it's always meaningful to hear a review from an outside developer. Today, we're sharing with you a review of our LEADTOOLS OCR Module - LEAD Engine written by Jeffrey T. Fritz

I live in an older house that loves to bother me with the joys of home ownership and maintenance. Plumbing issues, strange electrical installation choices, and a 30-year-old furnace that burns oil. At first, the oil burner wasn’t a big deal because this meant I wasn’t paying for an electric heater. However, it did mean that my basement had a huge oil tank hiding in it that would need to be refilled on a regular basis during the cold winters. That shouldn’t be a problem... but I would never know the level of the oil in the tank unless I wandered down to the basement on a regular basis and checked the level by reading an old gauge mounted on the top of the tank.

As a technologist, this daily task of reading the oil tank gauge became tiresome and I had no way to know how quickly I was burning oil. What is the correlation between average daily temperature and the amount of oil my furnace burns? I wanted to solve the problem and started with a pad of paper and wrote down the daily readings. BORING! Who wants to read hard copy? I want this data on my phone, and I want to be collected without my daily trip to the basement to read the meter.

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 Faris.

What it Does

This C# console application will scan a page, extract text with OCR and save to PDF using LEADTOOLS Version 19.

Some things you just have to see to believe, and we think that LEADTOOLS V19's new Invoice Recognition and Processing SDK is one of them. Now you can in our latest YouTube video!

If you have any familiarity with Forms Recognition and/or OCR, you may understand that those technologies typically rely on the master template and the document you wish to recognize having the same layout and proportions. Tax forms and applications fit this nicely since as long as the documents can get cleaned up and aligned, the zones and fields on the form to recognize will easily be found. Invoices, bills and other unstructured documents need special processing which LEADTOOLS masterfully developed and exposed in this new programmer-friendly toolkit. We hope you enjoy the video!
