Barcode Quickstart

IronBarcode supports various standard formats, from image files (jpeg, png, and jpg) to more programmatic formats where you would want to pass the variables around, such as a bitmap. Furthermore, it also supports external formats such as PDF, allowing IronBarcode to integrate seamlessly in any codebase, giving developers flexibility with file formats and variables.

Aside from being a barcode reader for all file formats, IronBarcode also doubles as a barcode generator that supports all standard encoding and formatting, such as the EAN8, Code128, and Code39. Setting the barcode generator up only takes two lines of code. With a low barrier of entry and plenty of customization options for developers, IronBarcode is the number one choice for all situations related to barcodes.

Barcode Reader and Barcode Generator in C#

var myBarcode = BarcodeWriter.CreateBarcode("12345", BarcodeEncoding.EAN8);
Image myBarcodeImage = myBarcode.ToImage();
myBarcode.ResizeTo(400, 100);
var resultFromFile = BarcodeReader.Read(@"file/barcode.png");
var myOptionsExample = new BarcodeReaderOptions { /* Options */ };

Barcode Writer

We first import the necessary libraries such as IronBarCode and System.Drawing, and instantiate BarcodeWriter to create a barcode with the string value of 12345 with the format of EAN8. We then save the generated barcode as an image in the desired format. There are various options for this as IronBarcode supports creating the barcode as an Image as well as a Bitmap.

Advanced Barcode Writer

As seen from above, generating a barcode using IronBarcode requires only two lines of code and saving it as a file for later usage. IronBarcode further extends this by providing developers with a plethora of options to customize the barcode to match the situation.

We can use the ResizeTo method and pass in the height and width to resize the barcode image.

Barcode Reader

Like the above, we first instantiate BarcodeReader, pass the file path to the Read method, and save it as a variable to use later and manipulate the barcode object. There are specified methods for reading external formats such as PDF with ReadPdf; however, for general image formats and bitmaps, we would use Read.

BarcodeReaderOptions

IronBarcode allows developers to scan barcodes from standard file format. However, there are situations where the developers want to fine-tune the behavior of the BarcodeReaderOptions class, especially in cases where it is reading a batch of barcode files programmatically. This is where BarcodeReaderOptions comes in. IronBarcode lets you fully customize things such as the speed at which it reads with Speed, whether multiple barcodes are expected in the file with ExpectMultipleBarcodes, and what kind of barcodes they are with the property ExpectBarcodeTypes. This allows developers to run multiple threads to read barcodes from multiple images in parallel, as well as control the number of threads used when doing parallel reading.

These are just some of the properties that showcase the power of IronBarcode. For a complete list, please refer to the documentation here.
