Extract Images from PDF

Introduction

In this tutorial, we will explore how to use GroupDocs.Parser for .NET to extract images from PDF documents. GroupDocs.Parser is a powerful library that enables developers to work with various document formats, including PDF, DOCX, PPTX, and more, in a .NET environment. By following these steps, you’ll be able to extract images from PDF files effortlessly.

Prerequisites

Before we begin, ensure you have the following prerequisites:

• Visual Studio installed on your system
• Basic knowledge of C# programming
• GroupDocs.Parser for .NET library (Download here)

Import Namespaces

To start, include the necessary namespaces in your C# code file.

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

Step 1: Create an Instance of Parser Class

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

// Create an instance of Parser class
using (Parser parser = new Parser("YourSampleFile.pdf"))
{
    // Code to extract images will go here
}

Step 2: Extract Images from PDF

Within the using block, utilize the GetImages method of the Parser instance to retrieve a collection of images from the PDF document.

// Extract images from the PDF
IEnumerable<PageImageArea> images = parser.GetImages();

Step 3: Configure Image Saving Options

Define the options to specify how the extracted images should be saved. Here, we will save the images in PNG format.

// Create options to save images in PNG format
ImageOptions options = new ImageOptions(ImageFormat.Png);

Step 4: Iterate Over Extracted Images and Save

Iterate through each image in the images collection and save them to PNG files sequentially.

int imageNumber = 0;
foreach (PageImageArea image in images)
{
    // Save the image to a PNG file
    image.Save(imageNumber.ToString() + ".png", options);
    imageNumber++;
}

Conclusion

In this tutorial, we have demonstrated how to extract images from PDF documents using GroupDocs.Parser for .NET. By following these steps, you can seamlessly integrate image extraction functionality into your .NET applications.
