IBarcodeGenerator

IBarcodeGenerator interface

Public interface for barcode custom generator. Implementation should be provided by user.

public interface IBarcodeGenerator

Methods

Name	Description
GetBarcodeImage(BarcodeParameters)	Generate barcode image using the set of parameters (for DisplayBarcode field).
GetOldBarcodeImage(BarcodeParameters)	Generate barcode image using the set of parameters (for old-fashioned Barcode field).

Remarks

Generator instance should be passed through the BarcodeGenerator property.

Examples

Shows how to use a barcode generator.

Document doc = new Document();
            DocumentBuilder builder = new DocumentBuilder(doc);
            // We can use a custom IBarcodeGenerator implementation to generate barcodes,
            // and then insert them into the document as images.
            doc.FieldOptions.BarcodeGenerator = new CustomBarcodeGenerator();

            // Below are four examples of different barcode types that we can create using our generator.
            // For each barcode, we specify a new set of barcode parameters, and then generate the image.
            // Afterwards, we can insert the image into the document, or save it to the local file system.
