### Generate QR Bill as SVG

Source: https://github.com/manuelbl/swissqrbill/blob/master/README.md

Example demonstrating how to set up bill data and generate a QR bill in SVG format. Ensure necessary imports are included. The generated SVG is saved to a file.

```java
package net.codecrete.qrbill.examples;

import net.codecrete.qrbill.generator.Address;
import net.codecrete.qrbill.generator.Bill;
import net.codecrete.qrbill.generator.QRBill;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

public class QRBillExample {

    public static void main(String[] args) {

        // Setup bill
        Bill bill = new Bill();
        bill.setAccount("CH4431999123000889012");
        bill.setAmountFromDouble(199.95);
        bill.setCurrency("CHF");

        // Set creditor
        Address creditor = new Address();
        creditor.setName("Robert Schneider AG");
        creditor.setStreet("Rue du Lac");
        creditor.setHouseNo("1268/2/22");
        creditor.setPostalCode("2501");
        creditor.setTown("Biel");
        creditor.setCountryCode("CH");
        bill.setCreditor(creditor);

        // more bill data
        bill.setReference("210000000003139471430009017");
        bill.setUnstructuredMessage("Abonnement für 2020");

        // Set debtor
        Address debtor = new Address();
        debtor.setName("Pia-Maria Rutschmann-Schnyder");
        debtor.setStreet("Grosse Marktgasse");
        debtor.setHouseNo("28");
        debtor.setPostalCode("9400");
        debtor.setTown("Rorschach");
        debtor.setCountryCode("CH");
        bill.setDebtor(debtor);

        // Set output format
        BillFormat format = new BillFormat();
        format.setGraphicsFormat(GraphicsFormat.SVG);
        format.setOutputSize(OutputSize.QR_BILL_ONLY);
        format.setLanguage(Language.DE);
        bill.setFormat(format);

        // Generate QR bill
        byte[] svg = QRBill.generate(bill);

        // Save QR bill
        Path path = Paths.get("qrbill.svg");
        try {
            Files.write(path, svg);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }

        System.out.println("QR bill saved at " + path.toAbsolutePath());
    }
```

### Generate QR Bill in Kotlin

Source: https://github.com/manuelbl/swissqrbill/blob/master/examples/kotlin_example/README.md

This snippet shows the fundamental steps to create a QR bill using Kotlin. It requires the necessary QR bill library to be included in your project.

```kotlin
import ch.fha.qr.model.QRBill
import ch.fha.qr.generator.QRBillGenerator

fun main() {
    // Create a QRBill object with necessary details
    val qrBill = QRBill(
        amount = 100.50,
        currency = "CHF",
        beneficiary = "Beneficiary Name",
        address = "Beneficiary Address",
        reference = "RF12345678901234567890",
        message = "Payment for invoice 12345"
    )

    // Generate the QR bill image
    val generator = QRBillGenerator()
    val qrCodeImage = generator.generate(qrBill)

    // Save or display the QR code image
    // For example, save to a file:
    // qrCodeImage.save("qr_bill.png")
    println("QR Bill generated successfully.")
}
```

### Generate QR Bill as PNG

Source: https://github.com/manuelbl/swissqrbill/wiki/Generate-PNG-files

Generates a QR bill and saves it as a PNG file. Requires a PNGCanvas instance with a specified resolution. A resolution of 144 pixels per inch is recommended.

```java
package net.codecrete.qrbill.examples;

import net.codecrete.qrbill.generator.Address;
import net.codecrete.qrbill.generator.Bill;
import net.codecrete.qrbill.generator.QRBill;

import net.codecrete.qrbill.canvas.PNGCanvas;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

public class QRBillExample {

    public static void main(String[] args) {

        // Setup bill
        Bill bill = new Bill();
        bill.setLanguage(Bill.Language.fr);
        bill.setAccount("CH4431999123000889012");
        // ...
        // see https://github.com/manuelbl/SwissQRBill
        // ...
        debtor.setCountryCode("CH");
        bill.setDebtor(debtor);

        PNGCanvas canvas = new PNGCanvas(144);
        byte[] png = QRBill.generate(bill, canvas);

        Path path = Paths.get("qrbill.png");
        try {
            Files.write(path, png);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
        System.out.println("QR bill saved at " + path.toAbsolutePath());
    }
}
```

### Add QR Bill to Existing PDF (C# with iText 7)

Source: https://github.com/manuelbl/swissqrbill/wiki/Add-to-existing-PDF

This C# snippet demonstrates adding a QR bill to an existing PDF using iText 7. It requires the Bill data, paths to the input and output PDFs, and a custom IText7Canvas implementation.

```csharp
Bill bill = ...; // bill data
string invoiceWithoutQRBill = ...; // path to existing PDF
string invoiceWithQRBill = ...; // path to new PDF
using (FileStream fs = new FileStream(invoiceWithQRBill, FileMode.Create))
using (IText7Canvas canvas = new IText7Canvas(OpenPdfInvoice(invoiceWithoutQRBill), fs, IText7Canvas.LastPage))
{
    QRBill.Draw(bill, canvas);
}
```

--------------------------------

### Add Gradle Dependency for QR Bill Generator

Source: https://github.com/manuelbl/swissqrbill/blob/master/README.md

Add this line to your Gradle project's build.gradle file to include the QR bill generator library.

```gradle
implementation "net.codecrete.qrbill:qrbill-generator:3.4.0+"
```

--------------------------------

### Add Maven Dependency for QR Bill Generator

Source: https://github.com/manuelbl/swissqrbill/blob/master/README.md

Include this dependency in your Maven project's pom.xml to use the QR bill generator library.

```xml
<dependency>
        <groupId>net.codecrete.qrbill</groupId>
        <artifactId>qrbill-generator</artifactId>
        <version>[3.4.0,3.999999]</version>
    </dependency>
```

--------------------------------

### Add QR Bill to Last Page (Java)

Source: https://github.com/manuelbl/swissqrbill/wiki/Add-to-existing-PDF

Use this Java snippet to add a QR bill to the last page of an existing PDF. Ensure you have the Bill data and paths for the input and output PDFs.

```java
Bill bill = ...; // bill data
Path invoiceWithoutQRBill = ...; // path to existing PDF
Path invoiceWithQRBill = ...; // path to new PDF
try (PDFCanvas canvas = new PDFCanvas(invoiceWithoutQRBill, PDFCanvas.LAST_PAGE)) {
    QRBill.draw(bill, canvas);
    canvas.saveAs(invoiceWithQRBill);
}
```

--------------------------------

### Disable SVG Shape Conversion in Jasper Reports

Source: https://github.com/manuelbl/swissqrbill/blob/master/examples/jasper_reports_rendering/README.md

This property can be set to control SVG shape conversion in Jasper Reports. However, it may not have a significant effect when Batik is used in the graphics pipeline.

```properties
net.sf.jasperreports.export.pdf.force.svg.shapes=false
```
