UPC-E1 is a compact variation of the UPC-A barcode designed for small-package labeling where space is limited. It uses number system 1 and derives its check digit from the corresponding expanded UPC-A representation.

Configure UPC-E1 Settings

Use the UPCE1Options class to configure UPC-E1 barcode settings.

The following code snippet creates a UPC-E1 barcode and customizes its encoding parameters:

import com.devexpress.drawing.*;
import com.devexpress.docs.barcode.*;
import com.devexpress.system.drawing.*;
import com.devexpress.docs.Padding;

import java.io.*;
import java.nio.file.*;

public class Main {
    public static void main(String[] args) throws Exception {

        UPCE1Options options = new UPCE1Options();
        options.setPadding(new Padding(10));
        options.setModuleSize(10);
        options.setShowText(true);
        options.setWidth(600);
        options.setHeight(200);

        Path outputDir = Path.of("output");
        Files.createDirectories(outputDir);

        try (FileOutputStream fileStream = new FileOutputStream(
                outputDir.resolve("upc-e1.png").toFile());
                BarcodeGenerator barcodeGenerator = new BarcodeGenerator(options)) {
                    barcodeGenerator.export(
                            "4210000526",
                            fileStream,
                            DXImageFormat.getPng());
        }
    }
}

Fluent API

Use the UPCE1OptionsBuilder class to configure UPC-E1 barcode settings with the Fluent API.

The following code snippet creates a UPC-E1 barcode and customizes its encoding parameters with the Fluent API:

import com.devexpress.drawing.*;
import com.devexpress.docs.barcode.*;
import com.devexpress.system.drawing.*;
import com.devexpress.docs.Padding;

import java.io.*;
import java.nio.file.*;

public class Main {
    public static void main(String[] args) throws Exception {

        UPCE1Options options = UPCE1OptionsBuilder.create()
            .withPadding(new Padding(10))
            .withModuleSize(10)
            .withShowText(true)
            .withWidth(600)
            .withHeight(200)
            .build();

        Path outputDir = Path.of("output");
        Files.createDirectories(outputDir);

        try (FileOutputStream fileStream = new FileOutputStream(
                outputDir.resolve("upc-e1.png").toFile());
                BarcodeGenerator barcodeGenerator = new BarcodeGenerator(options)) {
                    barcodeGenerator.export(
                            "4210000526",
                            fileStream,
                            DXImageFormat.getPng());
        }
    }
}
