Install-Package BarCode

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 Read method, 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 ExpectedMultipleBarcodes, 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.

IronBarcode offers many image pre-processing filters to choose from that are easily applied within BarcodeReaderOptions. Select the filters that may improve reading of your image such as Sharpen, Binary Threshold, and Contrast. Please keep in mind that the order in which you choose them is the order that they are applied.

There is the option of saving the image data of the intermediate images with each filter applied. This can be toggled with the SaveAtEachIteration property of ImageFilterCollection.

Key Points from the Featured Code Example:

We create an instance of BarcodeReaderOptions and configure it with various image filters: Sharpen, Binary Threshold, and Contrast.
The filters are added in a specific order, indicating the sequence in which they should be applied.
By setting cacheAtEachIteration to true, the library saves intermediate images after each filter application, which is useful for debugging and analysis.
Finally, we read the barcode from the image and print the barcode type and value to the console.

In this example, we see that barcodes of many different types and formats can be created, resized, and saved; possibly even in a single line of code.

Using our fluent API, the generated barcode class can be used to set margins, resize, and annotate barcodes. They may then be saved as images with IronBarcode automatically assuming the correct image type from a file name: GIFs, HTML files, HTML tags, JPEGs, PDFs, PNGs, TIFFs, and Windows Bitmaps.

We also have the StampToExistingPdfPage method, which allows a barcode to be generated and stamped onto an existing PDF. This is useful when editing a generic PDF or adding an internal identification number to a document via a barcode.

In this sample, we see that barcodes may be annotated with text of your choosing or the barcode's own value using any typeface which is installed on the target machine. If that typeface is not available, an appropriate similar typeface will be chosen. Barcodes may be resized, have margins added, and both the barcode and the background may be recolored. They may then be saved as an appropriate format.

In the final few lines of code, you can see that using our fluent style operators, it's possible to create and style a barcode in only a few lines of code, similar to System.Linq.

Exportar códigos de barras a HTML

// Save as a stand-alone HTML file without any image assets

// Save as a stand-alone HTML image tag which can be served in HTML files, ASPX or MVC Views. No image assets required, the tag embeds the entire image in its source content
string ImgTag = MyBarCode.ToHtmlTag();

// Turn the image into a HTML/CSS Data URI.
string DataURI = MyBarCode.ToDataUrl();

Imports IronBarCode

Private MyBarCode As GeneratedBarcode = BarcodeWriter.CreateBarcode("1234567890", BarcodeWriterEncoding.Code128)

' Save as a stand-alone HTML file without any image assets
MyBarCode.SaveAsHtmlFile("MyBarCode.html")

IronBarcode has a very useful feature allowing barcodes to be exported as HTML that is self-contained, such that it has no associated image assets. Everything is contained within the HTML file.

We may export as an HTML file, HTML image tag, or to a data URI.

In this example:

We create a barcode using BarcodeWriter.CreateBarcode, specifying the input data and encoding type.
We then use different methods provided by IronBarcode to export the barcode:
ToHtmlTag() generates an HTML <img> tag that can be embedded in web pages.
ToDataUri() creates a data URI string which can be used as a source for <img> tags or virtually anywhere an image URL is needed.
SaveAsHtmlFile() saves the barcode as a standalone HTML file, containing all image data inline, making it portable and easy to share.
