|
Read and write QR codes in C# VB ASP .NET desktop and web applications.
Iron Barcode is an example of a high-quality QR code library for C# and .NET. Iron Barcode can read QR codes from native System.Drawing.Image and Bitmap objects in addition to any modern image formats, scans, photographs, and PDF documents.
IronBarcode provides unique functionality for styling QR codes in .NET. Using a fluent API, we can style a QR code: re-scale, add margins, annotations, and change all of the colors, in a single line of code. Iron Barcode also provides functionality for .NET developers to: specify exactly the error correction rate within a QR code, add a logo to the QR code (automatically snapped to grid), all using the QR Code Writer class in the Iron Barcode namespace. Typically we read QR codes when processing a batch of documents, uploaded document, mobile phone camera photo, or webcam scan. When we write QR codes, we output them as images - Iron Barcode also offers the option to output them to screen, PDF, and even HTML.
