Custom Tab Stops In PDF File

This tutorial will guide you through the process of creating custom tab stops 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 create custom tab stops, add the following using directives 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 instance

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

Document _pdfdocument = 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 = _pdfdocument.Pages.Add();

Step 6: Create custom tab stops

Create a TabStops object and add custom tab stops to it. Set the alignment type and leader type for each tab stop.

TabStops ts = new TabStops();
TabStop ts1 = ts.Add(100);
ts1.AlignmentType = TabAlignmentType.Right;
ts1.LeaderType = TabLeaderType.Solid;

TabStop ts2 = ts.Add(200);
ts2.AlignmentType = TabAlignmentType.Center;
ts2.LeaderType = TabLeaderType.Dash;

TabStop ts3 = ts.Add(300);
ts3.AlignmentType = TabAlignmentType.Left;
ts3.LeaderType = TabLeaderType.Dot;

Step 7: Create text fragments with tab stops

Create TextFragment objects and pass the custom tab stops to them. Use the special characters #$TAB to indicate the tab stops within the text.

TextFragment header = new TextFragment("This is an example of forming a table with TAB stops", ts);
TextFragment text0 = new TextFragment("#$TABHead1 #$TABHead2 #$TABHead3", ts);
TextFragment text1 = new TextFragment("#$TABdata11 #$TABdata12 #$TABdata13", ts);
TextFragment text2 = new TextFragment("#$TABdata21 ", ts);
text2.Segments.Add(new TextSegment("#$TAB"));
text2.Segments.Add(new TextSegment("data22 "));
text2.Segments.Add(new TextSegment("#$TAB"));
text2.Segments.Add(new TextSegment("data23"));

page.Paragraphs.Add(header);
page.Paragraphs.Add(text0);
page.Paragraphs.Add(text1);
page.Paragraphs.Add(text2);

Step 8: Save the PDF document

Save the PDF document using the Save method of the Document object.

_pdfdocument.Save(dataDir);
Console.WriteLine("\nCustom tab stops setup successfully.\nFile saved at " + dataDir);

Sample source code for Custom Tab Stops using Aspose.PDF for .NET

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
Document _pdfdocument = new Document();
Page page = _pdfdocument.Pages.Add();
Aspose.Pdf.Text.TabStops ts = new Aspose.Pdf.Text.TabStops();
Aspose.Pdf.Text.TabStop ts1 = ts.Add(100);
ts1.AlignmentType = TabAlignmentType.Right;
ts1.LeaderType = TabLeaderType.Solid;
Aspose.Pdf.Text.TabStop ts2 = ts.Add(200);
ts2.AlignmentType = TabAlignmentType.Center;
ts2.LeaderType = TabLeaderType.Dash;
Aspose.Pdf.Text.TabStop ts3 = ts.Add(300);
ts3.AlignmentType = TabAlignmentType.Left;
ts3.LeaderType = TabLeaderType.Dot;
TextFragment header = new TextFragment("This is a example of forming table with TAB stops", ts);
TextFragment text0 = new TextFragment("#$TABHead1 #$TABHead2 #$TABHead3", ts);
TextFragment text1 = new TextFragment("#$TABdata11 #$TABdata12 #$TABdata13", ts);
TextFragment text2 = new TextFragment("#$TABdata21 ", ts);
text2.Segments.Add(new TextSegment("#$TAB"));
text2.Segments.Add(new TextSegment("data22 "));
text2.Segments.Add(new TextSegment("#$TAB"));
text2.Segments.Add(new TextSegment("data23"));
page.Paragraphs.Add(header);
page.Paragraphs.Add(text0);
page.Paragraphs.Add(text1);
page.Paragraphs.Add(text2);
dataDir = dataDir + "CustomTabStops_out.pdf";
_pdfdocument.Save(dataDir);
Console.WriteLine("\nCustom tab stops setup successfully.\nFile saved at " + dataDir);

Conclusion

You have successfully created a PDF document with custom tab stops using Aspose.PDF for .NET. The resulting PDF file can now be found at the specified output file path.
