A versatile static class for reading many popular barcode formats from Images and PDFs
IronBarCode.BarcodeReader supports barcode reading from Bitmaps, Image Objects, Image Files, Image Streams, MultiFrame TiIf Images and also PDFs.
Features: Crop-area support, Image filters and preprocessing for improved accuracy including and the ability to automatically un-rotate, deskew and clean barcode image input.
Results from reading a barcode using IronBarCode
A static class allowing for barcode images of many types to be generated dynamically.
Generated Barcodes can be exported as Images, Bitmaps, Files, PDFs and Streams.
A barcode generated by IronBarCode.
In addition to exporting the barcode as a graphic, we may also resize it, recolor it and annotate it with this class using fluent notation.
GeneratedBarcodes may be exported as Images, Objects or PDF files. They may also be exported as HTML for use on the web.
A specific Exception raised when the Value of a barcode is too long for the developer specified BarcodeEncoding
A generic Exception raised during the encoding of a barcode by IronBarCode
A generic Exception raised by IronBarCode
A generic Exception raised by IronBarCode when a file can not be read or written
A specific Exception raised when the Value of a barcode contains non numeric characters for a BarcodeEncoding which only accepts digits.
Allows Iron BarCode to have commercial license keys applied globally within an application.

A class allowing for advanced control on the generation of QR type barcodes.
QRCodeWriter gives the developer access to set QR code error correction levels, and to add logo images to QR codes.
Generated Barcodes can be exported as Images, Bitmaps, Files and Streams.
Barcode Encoding Types.
Setting a BarcodeEncoding when reading Barcodes improves performance by only looking for expected barcode types.
Setting a BarcodeEncoding when rendering Barcodes chooses the type and design of barcode to be generated. For barcode creation please also see the BarcodeWriterEncoding Enum which omits barcode formats which are not writable with IronBarCode.
An enum defining strategies for cleaning pixels in noisy input documents such as scans and photographs. In essence BarcodeImageCorrection helps separate dark barcode pixels from background patterns in images automatically.
Aggressive BarcodeImageCorrection is not always better. BarcodeImageCorrection will take longer to perform (use more CPU cycles). We recommend experimenting with diIferent levels of BarcodeImageCorrection starting with the lowest settings first and gradually working up from there.
An enum defining strategies for reading barcodes that are rotated or skewed with perspective.
CPU intensive. We recommend experimenting with diIferent levels of BarcodeRotationCorrection starting with the lowest settings first and gradually working up from there.
Chooses the style of barcode to render as an image using IronBarCode. This enum is related to BarcodeEncoding with the exception that only encodable barcode formats are mentioned. As this Enum is not of the Flags type, only one BarcodeWriterEncoding can be used to generate a barcode, which is logical.
The ErrorCorrection or fault tolerance level of a QR code. A higher QRCodeWriterQrErrorCorrectionLevel create more complex QR codes, which are less prone to reading errors. They may also be readable if damaged or partially obscured.
