Multicolumn Paragraphs In PDF File

In this tutorial, we will explain how to work with multicolumn paragraphs in PDF file using the Aspose.PDF library for .NET. We will go through the step-by-step process of manipulating and accessing multicolumn paragraphs using the provided C# source code.

Requirements

Before you begin, ensure that you have the following:

  • The Aspose.PDF for .NET library installed.
  • A basic understanding of C# programming.

Step 1: Set up the Document Directory

First, you need to set the path to the directory where your input PDF file is located. Replace "YOUR DOCUMENT DIRECTORY" in the dataDir variable with the path to your PDF file.

string dataDir = "YOUR DOCUMENT DIRECTORY";

Step 2: Load the PDF Document

Next, we load the input PDF document using the Document class from the Aspose.PDF library.

Document doc = new Document(dataDir + "MultiColumnPdf.pdf");

Step 3: Access Multicolumn Paragraphs

We use the ParagraphAbsorber class to absorb and visit the paragraphs in the PDF document. We then retrieve the page markups and access the multicolumn paragraphs.

ParagraphAbsorber absorb = new ParagraphAbsorber();
absorb.Visit(doc);
PageMarkup markup = absorb.PageMarkups[0];

Step 4: Work with Multicolumn Paragraphs

We access specific sections and paragraphs within the multicolumn structure and print their text.

Console.WriteLine("IsMulticolumnParagraphsAllowed == false\r\n");

// Accessing the last paragraph in a section
MarkupSection section = markup.Sections[2];
MarkupParagraph paragraph = section.Paragraphs[section.Paragraphs.Count - 1];
Console.WriteLine("Section at {0} last paragraph text:\r\n", section.Rectangle.ToString());
Console.WriteLine(paragraph.Text);

// Accessing the first paragraph in a section
section = markup. Sections[1];
paragraph = section.Paragraphs[0];
Console.WriteLine("\r\nSection at {0} first paragraph text:\r\n", section.Rectangle.ToString());
Console.WriteLine(paragraph.Text);

// Enabling multicolumn paragraphs
markup.IsMulticolumnParagraphsAllowed = true;
Console.WriteLine("\r\nIsMulticolumnParagraphsAllowed == true\r\n");

// Accessing the last paragraph in a section after enabling multicolumn paragraphs
section = markup. Sections[2];
paragraph = section.Paragraphs[section.Paragraphs.Count - 1];
Console.WriteLine("Section at {0} last paragraph text:\r\n", section.Rectangle.ToString());
Console.WriteLine(paragraph.Text);

// Accessing the first paragraph in a section after enabling multicolumn paragraphs
section = markup. Sections[1];
paragraph = section.Paragraphs[0];
Console.WriteLine("\r\nSection at {0} first paragraph text:\r\n", section.Rectangle.ToString());
Console.WriteLine(paragraph.Text);

Sample source code for Multicolumn Paragraphs using Aspose.PDF for .NET

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
Document doc = new Document(dataDir + "MultiColumnPdf.pdf");
ParagraphAbsorber absorber = new ParagraphAbsorber();
absorber.Visit(doc);
PageMarkup markup = absorber.PageMarkups[0];
Console.WriteLine("IsMulticolumnParagraphsAllowed == false\r\n");
MarkupSection section = markup.Sections[2];
MarkupParagraph paragraph = section.Paragraphs[section.Paragraphs.Count - 1];
Console.WriteLine("Section at {0} last paragraph text:\r\n", section.Rectangle.ToString());
Console.WriteLine(paragraph.Text);
section = markup.Sections[1];
paragraph = section.Paragraphs[0];
Console.WriteLine("\r\nSection at {0} first paragraph text:\r\n", section.Rectangle.ToString());
Console.WriteLine(paragraph.Text);
markup.IsMulticolumnParagraphsAllowed = true;
Console.WriteLine("\r\nIsMulticolumnParagraphsAllowed == true\r\n");
section = markup.Sections[2];
paragraph = section.Paragraphs[section.Paragraphs.Count - 1];
Console.WriteLine("Section at {0} last paragraph text:\r\n", section.Rectangle.ToString());
Console.WriteLine(paragraph.Text);
section = markup.Sections[1];
paragraph = section.Paragraphs[0];
Console.WriteLine("\r\nSection at {0} first paragraph text:\r\n", section.Rectangle.ToString());
Console.WriteLine(paragraph.Text);
