Import PDF Documents into Aspose.Note

Introduction

With the vast amount of digital content available today, integrating PDF documents into your projects seamlessly is crucial. Aspose.Note for .NET provides powerful functionalities to import PDF documents efficiently. In this tutorial, we’ll explore how to import PDF documents step by step using Aspose.Note for .NET.

Prerequisites

Before diving into the tutorial, ensure you have the following:

1. Aspose.Note for .NET: Download and install the library from here.
2. Basic knowledge of C# and .NET Framework: Understanding of C# programming language and .NET Framework will be beneficial.

Import Namespaces

Make sure to import the necessary namespaces to access the classes and methods required for PDF import functionality:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;

using Aspose.Note.Importing;

Step 1: Import PDF Documents using Simple Merge

The Simple Merge approach allows importing all pages from multiple PDF documents page by page:

public static void ImportSetOfFiles_SimpleMerge()
{
    string dataDir = "Your Document Directory";

    var d = new Document();

    d.Import(Path.Combine(dataDir, "sampleText.pdf"))
     .Import(Path.Combine(dataDir, "sampleImage.pdf"))
     .Import(Path.Combine(dataDir, "sampleTable.pdf"));

    d.Save(Path.Combine(dataDir, "sample_SimpleMerge.one"));

    Console.WriteLine("\nThe PDF documents are imported successfully.");
}

Step 2: Import PDF Documents using Structured Merge

Structured Merge imports all pages from PDF documents while inserting pages from each document as children of a top-level OneNote page:

public static void ImportSetOfFiles_StructuredMerge()
{
    string dataDir = "Your Document Directory";

    var d = new Document();

    foreach (var file in new[] { "sampleText.pdf", "sampleImage.pdf", "sampleTable.pdf" })
    {
        d.AppendChildLast(new Page()).Title = new Title() { TitleText = new RichText() { ParagraphStyle = ParagraphStyle.Default }.Append(file) };
        d.Import(Path.Combine(dataDir, file), new PdfImportOptions(), new MergeOptions() { InsertAt = int.MaxValue, InsertAsChild = true });
    }

    d.Save(Path.Combine(dataDir, "sample_StructuredMerge.one"));

    Console.WriteLine("\nThe PDF documents are imported successfully.");
}

Step 3: Import PDF Documents using Single Page Merge

Single Page Merge merges content from multiple PDF documents onto a single OneNote page:

public static void ImportSetOfFiles_SinglePageMerge()
{
    string dataDir = "Your Document Directory";

    var d = new Document();

    var importOptions = new PdfImportOptions();
    var mergeOptions = new MergeOptions() { ImportAsSinglePage = true, PageSpacing = 100 };

    d.Import(Path.Combine(dataDir, "sampleText.pdf"), importOptions, mergeOptions)
     .Import(Path.Combine(dataDir, "sampleImage.pdf"), importOptions, mergeOptions)
     .Import(Path.Combine(dataDir, "sampleTable.pdf"), importOptions, mergeOptions);

    d.Save(Path.Combine(dataDir, "sample_SinglePageMerge.one"));

    Console.WriteLine("\nThe PDF documents are imported successfully.");
}

Step 4: Import PDF Documents using Custom Merge

Custom Merge allows grouping pages from PDF documents into single OneNote pages based on custom criteria:

public static void ImportSetOfFiles_CustomMerge()
{
    string dataDir = "Your Document Directory";

    var d = new Document();

    var mergeOptions = new MergeOptions() { ImportAsSinglePage = true, PageSpacing = 100 };

    IEnumerable<Page> pages = PdfImporter.Import(Path.Combine(dataDir, "SampleGrouping.pdf"));
    while (pages.Any())
    {
        d.Merge(pages.Take(5), mergeOptions);
        pages = pages.Skip(5);
    }

    d.Save(Path.Combine(dataDir, "sample_CustomMerge.one"));

    Console.WriteLine("\nThe PDF documents are imported successfully.");
}
