Extract Images from Document

Introduction

In this tutorial, we will explore how to extract images from documents using GroupDocs.Parser for .NET. GroupDocs.Parser is a powerful library that enables developers to extract text, metadata, images, and more from various document formats.

Prerequisites

Before you begin, ensure you have the following prerequisites set up:

• Visual Studio: Install Visual Studio on your machine.
• GroupDocs.Parser for .NET: Download and install GroupDocs.Parser from the download page.
• Sample Document: Prepare a sample document (PDF, DOCX, etc.) from which you want to extract images.

Import Namespaces

Start by importing the necessary namespaces in your C# project:

using System;
using System.Collections.Generic;
using System.Text;
using GroupDocs.Parser.Data;

Step 1: Create an Instance of the Parser Class

First, create an instance of the Parser class by providing the path to your sample document.

using (Parser parser = new Parser("YourSampleFile.pdf"))
{
    // Your code goes here
}

Replace "YourSampleFile.pdf" with the path to your document file.

Step 2: Extract Images from the Document

Next, extract images from the document using the GetImages() method.

IEnumerable<PageImageArea> images = parser.GetImages();

The GetImages() method returns a collection of PageImageArea objects representing images found in the document.

Step 3: Check Images Extraction Support

Before iterating over the images, check if image extraction is supported for the document.

if (images == null)
{
    Console.WriteLine("Images extraction isn't supported");
    return;
}

This step ensures that the document contains extractable images.

Step 4: Iterate Over Extracted Images

Now, iterate over the extracted images to access detailed information about each image, such as page index, rectangle coordinates, and image type.

foreach (PageImageArea image in images)
{
    Console.WriteLine($"Page: {image.Page.Index}, Rectangle: {image.Rectangle}, Type: {image.FileType}");
}

This loop prints out information about each extracted image, including its location and type.

Conclusion

In this tutorial, we learned how to use GroupDocs.Parser for .NET to extract images from documents programmatically. By following these steps, you can integrate document image extraction functionality into your .NET applications seamlessly.
