Converting TIFF to PDF in C# Using Aspose.Imaging

Converting TIFF images to PDF format is a common requirement for many applications, especially when dealing with scanned documents or high-resolution images. This tutorial will guide you through the process of converting TIFF files to PDF using C#, leveraging the powerful features provided by the Aspose.Imaging library.

Benefits of Converting TIFF to PDF

  1. Universal Compatibility: PDF files can be viewed on virtually any device or platform.
  2. Document Preservation: Maintains the original quality and layout of the TIFF file.
  3. Enhanced Security: PDFs allow for encryption and password protection, ensuring that your documents are secure.

Prerequisites: Preparing the Environment

To get started with converting TIFF to PDF in C#, you need to set up your development environment properly:

  1. Install Visual Studio or any compatible .NET IDE.
  2. Add the Aspose.Imaging library via command: bash dotnet add package Aspose.Imaging
using Aspose.Imaging;
using Aspose.Imaging.FileFormats.Pdf;

class Program
{
    static void Main(string[] args)
    {
        // Initialize metered license
        Metered metered = new Metered();
        metered.SetMeteredKey("your-public-key", "your-private-key");

        string tiffFilePath = @"path\to\input.tiff";
        string pdfOutputPath = @"path\to\output.pdf";

        using (Image image = Image.Load(tiffFilePath))
        {
            PdfOptions options = new PdfOptions();
            // Customize the output settings as needed
            options.VectorRasterizationOptions.Resolution = 300;

            image.Save(pdfOutputPath, options);
        }
    }
}

Understanding the Code

Let’s break down the key parts of this implementation:

Step 1: Initial Setup

First, we initialize the metered license and load the input file:

// Initialize metered license
Metered metered = new Metered();
metered.SetMeteredKey("your-public-key", "your-private-key");

string tiffFilePath = @"path\to\input.tiff";
using (Image image = Image.Load(tiffFilePath))
{
    // Further processing...
}

This step ensures that the application is licensed to use Aspose.Imaging and loads the TIFF file into an Image object.

Step 2: Configuring Options

Next, we configure the conversion/processing options:

PdfOptions options = new PdfOptions();
options.VectorRasterizationOptions.Resolution = 300;

Here, we create a PdfOptions object and set its resolution to 300 DPI. This ensures that the output PDF maintains high quality.

Step 3: Performing the Operation

Now we execute the main operation:

image.Save(pdfOutputPath, options);

This line saves the TIFF image as a PDF file with the specified settings.

Conclusion

This tutorial has provided a detailed guide on how to convert TIFF images to PDF using C# and the Aspose.Imaging library. By following these steps, you can easily integrate this functionality into your applications, ensuring that your documents are universally accessible and secure.

Remember to replace "your-public-key" and "your-private-key" with actual keys from your Aspose account for production use.
