Add Subsequent Lines Indent In PDF File

This tutorial will guide you through the process of adding subsequent lines indent to text 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 add subsequent lines indent, add the following using directive at the top of the file:

using Aspose.Pdf;
using Aspose.Pdf.Text;

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 object

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

Aspose.Pdf.Document document = new Aspose.Pdf.Document();

Step 5: Add a page to the document

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

Aspose.Pdf.Page page = document.Pages.Add();

Step 6: Create a TextFragment with subsequent lines indent

Instantiate a TextFragment object and provide the desired text. In the provided code, the text is assigned to the variable text. Then, initialize TextFormattingOptions for the TextFragment and specify the SubsequentLinesIndent value.

Aspose.Pdf.Text.TextFragment text = new Aspose.Pdf.Text.TextFragment("A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog." );
text.TextState.FormattingOptions = new Aspose.Pdf.Text.TextFormattingOptions()
{
     SubsequentLinesIndent = 20
};

Step 7: Add the TextFragment to the page

Add the TextFragment object to the paragraphs collection of the page.

page.Paragraphs.Add(text);

Step 8: Repeat steps 6 and 7 for additional lines

To add subsequent lines with the same indent, repeat steps 6 and 7 for each line. Update the text content as needed.

text = new Aspose.Pdf.Text.TextFragment("Line2");
page.Paragraphs.Add(text);
text = new Aspose.Pdf.Text.TextFragment("Line3");
page.Paragraphs.Add(text);
text = new Aspose.Pdf.Text.TextFragment("Line4");
page.Paragraphs.Add(text);
text = new Aspose.Pdf.Text.TextFragment("Line5");
page.Paragraphs.Add(text);

Step 9: Save the PDF document

Save the PDF document using the Save method of the Document object. Specify the output file path.

document.Save(dataDir + "SubsequentIndent_out.pdf", Aspose.Pdf.SaveFormat.Pdf);

Sample source code for Add Subsequent Lines Indent using Aspose.PDF for .NET

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
// Create new document object 
Aspose.Pdf.Document document = new Aspose.Pdf.Document();
Aspose.Pdf.Page page = document.Pages.Add();
Aspose.Pdf.Text.TextFragment text = new Aspose.Pdf.Text.TextFragment("A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog. A quick brown fox jumped over the lazy dog.");
// Initilize TextFormattingOptions for the text fragment and specify SubsequentLinesIndent value
text.TextState.FormattingOptions = new Aspose.Pdf.Text.TextFormattingOptions()
{
	SubsequentLinesIndent = 20
};
page.Paragraphs.Add(text);
text = new Aspose.Pdf.Text.TextFragment("Line2");
page.Paragraphs.Add(text);
text = new Aspose.Pdf.Text.TextFragment("Line3");
page.Paragraphs.Add(text);
text = new Aspose.Pdf.Text.TextFragment("Line4");
page.Paragraphs.Add(text);
text = new Aspose.Pdf.Text.TextFragment("Line5");
page.Paragraphs.Add(text);
document.Save(dataDir + "SubsequentIndent_out.pdf", Aspose.Pdf.SaveFormat.Pdf);

Conclusion

You have successfully added subsequent lines indent to text using Aspose.PDF for .NET. The resulting PDF file can now be found at the specified output file path.
