GenerateBarcodewithLogo_CSharp_Barcode.cs

// This code example demonstrates how to generate a barcode with an image instead of code text.
// Create an instance of BarcodeGenerator class
// Set the barcode symbology 
// Set the barcode text
BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.EAN13, "1234567890");

// Set QR code size value in pixels
generator.Parameters.Barcode.XDimension.Pixels = 10;

// Generate Barcode image and store it in a Bitmap
Bitmap barcode = generator.GenerateBarCodeImage();

// Load the logo or other image as Bitmap
Bitmap picture = (Bitmap)Image.FromFile(@"D:\Files\BarCode\aspose-logo.png");

// Create a new empty image with new Calculated height & width
Bitmap output = new Bitmap(Math.Max(barcode.Width, picture.Width), barcode.Height + picture.Height);

// Get the Graphics object
using (Graphics g = Graphics.FromImage(output))
{
    // Clear the canvas 
    g.Clear(Color.White);

    // Draw the primary image (barcode image) on the canvas
    g.DrawImage(picture, new PointF(30, 0));

    // Draw the second image (logo image) on the canvas inside the barcode image
    g.DrawImage(barcode, new PointF(0, picture.Height));
}

// Save the output image
output.Save(@"D:\Files\BarCode\output.jpg");

// This code example demonstrates how to generate a barcode with an image instead of code text.
// Create an instance of BarcodeGenerator class

// Set QR code size value in pixels
generator.Parameters.Barcode.XDimension.Pixels = 10

// Generate Barcode image and store it in a Bitmap
Bitmap barcode = generator.GenerateBarCodeImage();

// Load the logo or other image as Bitmap
Bitmap picture = (Bitmap)Image.FromFile(@"D:\Files\BarCode\logo.png");

// Create a new empty image with new Calculated height & width

    g.DrawImage(barcode, new PointF(0, picture.Height));
}

// Save the output image
