For programmers who use the LEADTOOLS PDF SDK or the LEADTOOLS Document Viewer SDK this is an easy task! With minimal code, developers leveraging LEADTOOLS can easily provide users an interface to load and enter data into PDF form fields and then save the PDF.

Product Review: Updating 1980's Technology with the Help of 2017's Imaging Tools

Posted on 2022-02-15 09:15:20 by Gabriel Smith

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.

This week I'm starting simple, and highlighting the changes to the product line. Overall, Version 18 is a slimmer offering in terms of actual products, but there are more features and development interfaces than ever before (which I'll cover next week)!
