Allow Resuse Page Content

In this tutorial, we will explain how to enable the “Allow Resuse Page Content” feature using Aspose.PDF for .NET. This feature optimizes the PDF document by reusing page content, reducing file size and improving performance. Follow the step-by-step guide below:

Step 1: Load the PDF document

string dataDir = "YOUR DOCUMENT DIRECTORY";
Document pdfDocument = new Document(dataDir + "OptimizeDocument.pdf");

Step 2: Set the AllowReusePageContent option

var optimizeOptions = new Pdf.Optimization.OptimizationOptions
{
    AllowReusePageContent = true
};

Step 3: Optimize the PDF document

pdfDocument.OptimizeResources(optimizeOptions);

Step 4: Save the updated document

pdfDocument.Save(dataDir + "OptimizeDocument_out.pdf");

Step 5: Check the file size reduction

var fi1 = new System.IO.FileInfo(dataDir + "OptimizeDocument.pdf");
var fi2 = new System.IO.FileInfo(dataDir + "OptimizeDocument_out.pdf");
Console.WriteLine("Original file size: {0}. Reduced file size: {1}", fi1.Length, fi2.Length);

Congratulations! You have successfully allowed reuse of page content in your PDF document.

Example source code for Allowing Reuse of Page Content using Aspose.PDF for .NET:

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";

// Open document
Document pdfDocument = new Document(dataDir + "OptimizeDocument.pdf");

// Set AllowReusePageContent option
var optimizeOptions = new Pdf.Optimization.OptimizationOptions
{
    AllowReusePageContent = true
};

Console.WriteLine("Start");

// Optimize PDF document using OptimizationOptions
pdfDocument.OptimizeResources(optimizeOptions);

// Save updated document
pdfDocument.Save(dataDir + "OptimizeDocument_out.pdf");

Console.WriteLine("Finished");

var fi1 = new System.IO.FileInfo(dataDir + "OptimizeDocument.pdf");
var fi2 = new System.IO.FileInfo(dataDir + "OptimizeDocument_out.pdf");
Console.WriteLine("Original file size: {0}. Reduced file size: {1}", fi1.Length, fi2.Length);

Console.WriteLine("\nAllowed reuse of page content successfully.\nFile saved at " + dataDir);

Now you can effectively optimize your PDF documents by allowing reuse of page content.

FAQ’s

Q: What is the purpose of enabling the “Allow Reuse Page Content” feature in a PDF document?

A: Enabling the “Allow Reuse Page Content” feature in a PDF document optimizes the file by reusing page content, which reduces the file size and improves overall performance. This optimization results in smaller PDF files without compromising on content quality.

Q: How does the “Allow Reuse Page Content” feature work?

A: When the “Allow Reuse Page Content” feature is enabled, identical page objects within the PDF document are shared and reused, instead of being duplicated for each occurrence. This sharing of page content significantly reduces the overall file size.

Q: Can I revert the optimization and restore the original document?

A: No, once the optimization with “Allow Reuse Page Content” is performed and the PDF document is saved, the changes are permanent. It is advisable to keep a backup of the original document before performing any optimization.

Q: Will enabling this feature affect the visual appearance or content of the PDF document?

A: Enabling the “Allow Reuse Page Content” feature does not affect the visual appearance or content of the PDF document. It solely optimizes the internal structure of the file to reduce redundancy and enhance efficiency.

Q: Is Aspose.PDF for .NET a reliable solution for PDF optimization and manipulation?

A: Yes, Aspose.PDF for .NET is a reliable and feature-rich library for PDF optimization and manipulation. It offers extensive options to optimize PDF files, including reducing file size, removing unused resources, and enhancing overall performance.
