QR codes have solidified themselves as an integral part of modern information exchange, offering a quick and efficient way to store and retrieve data. With LEADTOOLS, you can extract over 100 barcode types from any of our 165+ supported file formats! In this blog post, we will specifically show how to extract QR codes from a PDF file in C# using the LEADTOOLS Barcode SDK and then save the extracted codes as images.

This video showcases how you can use the Visual Studio Xamarin template in combination with LEADTOOLS Barcode SDK libraries to create a simple Barcode Reader application. This sample application loads a QR Code test image and returns the symbology, position and value of the recognized QR code when the user selects the button.

We take great pride in the fact that LEADTOOLS is truly a comprehensive imaging SDK. We developed LEADTOOLS with the mindset that we want it to be a one-stop-shop for imaging. There are many applications, especially in the document imaging world, where technologies intersect and you may find the need to piecemeal multiple SDKs together. For example, Scanning + Document Cleanup + OCR, OMR + Forms Recognition + OCR, or OCR + PDF. How about something a little less common, like OCR + Barcode?

This post is part of our 2017 Developer App Series, which showcases apps created by our Support Agents over the course of eight weeks. These apps are intended to be larger, more thoughtful apps with highly practical purposes in mind, as opposed to a basic "how to" for a feature.

App Description

This project from Faris will allow the user to generate a readable QR Code using the LEADTOOLS Barcode SDK alongside the LEADTOOLS Annotations SDK to add a picture or logo inside the barcode while still keeping the barcode readable.

Our latest white paper contains a wealth of information on selecting the right barcode for your application. There are an abundance of barcode types and sub-types, so choosing correctly from the outset can have a profound impact on your application's entire development life cycle. Common problems could be using a barcode that doesn't hold enough information, is too rigid for evolutions in your application, takes up too much physical space, fails to read when damaged, and so on.

After an introduction into different types of barcodes and their uses, this white paper then helps navigate implementing them into your application. Not all barcode SDKs are created equal, and we dive into the many advantages — both for the developer and eventual end-user — of trusting LEADTOOLS in your application. We hope you enjoy the read!
