The C# Barcode Library

using IronBarCode; using System.Drawing; // Creating a barcode is as simple as: var myBarcode = BarcodeWriter.CreateBarcode("12345", BarcodeWriterEncoding.EAN8); // And save our barcode as in image: myBarcode.SaveAsImage("EAN8.jpeg"); Image myBarcodeImage = myBarcode.Image; // Can be used as Image Bitmap myBarcodeBitmap = myBarcode.ToBitmap(); // Can be used as Bitmap // Reading a barcode is easy with IronBarcode: var resultFromFile = BarcodeReader.Read(@"file/barcode.png"); // From a file var resultFromBitMap = BarcodeReader.Read(new Bitmap("barcode.bmp")); // From a bitmap var resultFromImage = BarcodeReader.Read(Image.FromFile("barcode.jpg")); // From an image var resultFromPdf = BarcodeReader.ReadPdf(@"file/mydocument.pdf"); // From PDF use ReadPdf // After creating a barcode, we may choose to resize and save which is easily done with: var myNewBarcode = BarcodeWriter.CreateBarcode("12345", BarcodeWriterEncoding.EAN8); myNewBarcode.ResizeTo(400, 100); myNewBarcode.SaveAsImage("myBarcodeResized.jpeg"); // To set more options and optimization with your Barcode Reading, // Please utilize the BarcodeReaderOptions paramter of read: var myOptionsExample = new BarcodeReaderOptions { // Choose a speed from: Faster, Balanced, Detailed, ExtremeDetail // There is a tradeoff in performance as more Detail is set Speed = ReadingSpeed.Balanced, // Reader will stop scanning once a barcode is found, unless set to true ExpectMultipleBarcodes = true, // By default, all barcode formats are scanned for. // Specifying one or more, performance will increase. ExpectBarcodeTypes = BarcodeEncoding.AllOneDimensional, // Utilizes multiple threads to reads barcodes from multiple images in parallel. Multithreaded = true, // Maximum threads for parallel. Default is 4 MaxParallelThreads = 2, // The area of each image frame in which to scan for barcodes. // Will improve performance significantly and avoid unwanted results and avoid noisy parts of the image. CropArea = new Rectangle(), // Special Setting for Code39 Barcodes. // If a Code39 barcode is detected. Try to use extended mode for the full ASCII Character Set UseCode39ExtendedMode = true }; // And, apply: var results = BarcodeReader.Read("barcode.png", myOptionsExample);
