Determine Line Break In PDF File

This tutorial will guide you through the process of determining line breaks in PDF file using Aspose.PDF for .NET. The provided C# source code demonstrates the necessary steps.

Requirements

Before you begin, ensure that you have the following:

  • Visual Studio or any other C# compiler installed on your machine.
  • Aspose.PDF for .NET library. You can download it from the official Aspose website or use a package manager like NuGet to install it.

Step 1: Set up the project

  1. Create a new C# project in your preferred development environment.
  2. Add a reference to the Aspose.PDF for .NET library.

Step 2: Import required namespaces

In the code file where you want to determine line breaks, add the following using directives at the top of the file:

using Aspose.Pdf;
using System.IO;

Step 3: Set the document directory

In the code, locate the line that says string dataDir = "YOUR DOCUMENT DIRECTORY"; and replace "YOUR DOCUMENT DIRECTORY" with the path to the directory where your documents are stored.

Step 4: Create a new Document instance

Instantiate a new Document object by adding the following line of code:

Document doc = new Document();

Step 5: Add a page to the document

Add a new page to the document using the Add method of the Pages collection. In the provided code, the new page is assigned to the variable page.

Page page = doc.Pages.Add();

Step 6: Add text fragments with line breaks

Create a loop to add multiple text fragments to the page, each containing a paragraph with line breaks.

for (int i = 0; i < 4; i++)
{
     TextFragment text = new TextFragment("Lorem ipsum \r\ndolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.
     text.TextState.FontSize = 20;
     page.Paragraphs.Add(text);
}

Step 7: Save the PDF document and extract line break information

Save the PDF document using the Save method of the Document object. Then, extract the line break information using the GetNotifications method of the desired page.

doc.Save(dataDir + "DetermineLineBreak_out.pdf");
string notifications = doc.Pages[1].GetNotifications();
File.WriteAllText(dataDir + "notifications_out.txt", notifications);

Sample source code for Determine Line Break using Aspose.PDF for .NET

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
Document doc = new Document();
Page page = doc.Pages.Add();
for (int i = 0; i < 4; i++)
{
	TextFragment text = new TextFragment("Lorem ipsum \r\ndolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.");
	text.TextState.FontSize = 20;
	page.Paragraphs.Add(text);
}
doc.Save(dataDir + "DetermineLineBreak_out.pdf");
string notifications = doc.Pages[1].GetNotifications();
File.WriteAllText(dataDir + "notifications_out.txt", notifications);

Conclusion

You have successfully determined line breaks in a PDF document using Aspose.PDF for .NET. The line break information has been extracted and saved to a text file.
