Create Multi Column Pdf

This tutorial will guide you through the process of creating a multi column PDF 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 a multi column PDF, add the following using directives at the top of the file:

using Aspose.Pdf;
using Aspose.Pdf.Drawing;

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: Set the page margins

Specify the left and right margin information for the PDF file using the PageInfo.Margin property of the Document.

doc.PageInfo.Margin.Left = 40;
doc.PageInfo.Margin.Right = 40;

Step 6: 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 7: Create a Graph object and add a line

Create a new Graph object with specific dimensions and add a line to it. Then, add the Graph object to the Paragraphs collection of the page.

Aspose.Pdf.Drawing.Graph graph1 = new Aspose.Pdf.Drawing.Graph(500, 2);
float[] backPos = new float[] { 1, 2, 500, 2 };
Aspose.Pdf.Drawing.Line l1 = new Aspose.Pdf.Drawing.Line(posArr);
graph1.Shapes.Add(l1);
page.Paragraphs.Add(graph1);

Step 8: Add heading text with HTML formatting

Create an HtmlFragment object and set its content to the desired HTML text. Then, add the fragment to the Paragraphs collection of the page.

string s = "<font face=\"Times New Roman\" size=4>" +
     "<strong>How to Steer Clear of money scams</<strong>" +
     "</font>";
HtmlFragment heading_text = new HtmlFragment(s);
page.Paragraphs.Add(heading_text);

Step 9: Create a FloatingBox with multiple columns

Create a FloatingBox object and set the number of columns and column spacing. Then, add text fragments and a line to the Paragraphs collection of the FloatingBox.

Aspose.Pdf.FloatingBox box = new Aspose.Pdf.FloatingBox();
box. ColumnInfo. ColumnCount = 2;
box.ColumnInfo.ColumnSpacing = "5";
box.ColumnInfo.ColumnWidths = "105 105";

TextFragment text1 = new TextFragment("By A Googling (The Official Google Blog)");
text1.TextState.FontSize = 8;
text1.TextState.LineSpacing = 2;
box.Paragraphs.Add(text1);

TextFragment text2 = new TextFragment("Sed augue tortor, sodales id, luctus et, pulvinar ut, eros. Suspendisse vel dolor. Sed quam. Curabitur ut massa vitae eros euismod aliquam...");
box.Paragraphs.Add(text2);

Aspose.Pdf.Drawing.Graph graph2 = new Aspose.Pdf.Drawing.Graph(50, 10);
float[] posArr2 = new float[] { 1, 10, 100, 10 };
Aspose.Pdf.Drawing.Line l2 = new Aspose.Pdf.Drawing.Line(posArr2);
graph2.Shapes.Add(l2);
box.Paragraphs.Add(graph2);

page.Paragraphs.Add(box);

Step 10: Save the PDF document

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

doc.Save(dataDir);

Sample source code for Create Multi Column Pdf using Aspose.PDF for .NET

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
Document doc = new Document();
// Specify the left margin info for the PDF file
doc.PageInfo.Margin.Left = 40;
// Specify the Right margin info for the PDF file
doc.PageInfo.Margin.Right = 40;
Page page = doc.Pages.Add();
Aspose.Pdf.Drawing.Graph graph1 = new Aspose.Pdf.Drawing.Graph(500, 2);
// Add the line to paraphraphs collection of section object
page.Paragraphs.Add(graph1);
// Specify the coordinates for the line
float[] posArr = new float[] { 1, 2, 500, 2 };
Aspose.Pdf.Drawing.Line l1 = new Aspose.Pdf.Drawing.Line(posArr);
graph1.Shapes.Add(l1);
// Create string variables with text containing html tags
string s = "<font face=\"Times New Roman\" size=4>" +
"<strong> How to Steer Clear of money scams</<strong> "
+ "</font>";
// Create text paragraphs containing HTML text
HtmlFragment heading_text = new HtmlFragment(s);
page.Paragraphs.Add(heading_text);
Aspose.Pdf.FloatingBox box = new Aspose.Pdf.FloatingBox();
// Add four columns in the section
box.ColumnInfo.ColumnCount = 2;
// Set the spacing between the columns
box.ColumnInfo.ColumnSpacing = "5";
box.ColumnInfo.ColumnWidths = "105 105";
TextFragment text1 = new TextFragment("By A Googler (The Official Google Blog)");
text1.TextState.FontSize = 8;
text1.TextState.LineSpacing = 2;
box.Paragraphs.Add(text1);
text1.TextState.FontSize = 10;
text1.TextState.FontStyle = FontStyles.Italic;
// Create a graphs object to draw a line
Aspose.Pdf.Drawing.Graph graph2 = new Aspose.Pdf.Drawing.Graph(50, 10);
// Specify the coordinates for the line
float[] posArr2 = new float[] { 1, 10, 100, 10 };
Aspose.Pdf.Drawing.Line l2 = new Aspose.Pdf.Drawing.Line(posArr2);
graph2.Shapes.Add(l2);
// Add the line to paragraphs collection of section object
box.Paragraphs.Add(graph2);
TextFragment text2 = new TextFragment(@"Sed augue tortor, sodales id, luctus et, pulvinar ut, eros. Suspendisse vel dolor. Sed quam. Curabitur ut massa vitae eros euismod aliquam.
