  2. Create an instance of the ImageExtractorOptions class.
  3. Add the input file path to the options.
  4. Process the image extraction using the plugin.
  5. Retrieve the extracted images from the result container.
​
 1using var plugin = new ImageExtractor();
 2
 3// Create an instance of the ImageExtractorOptions class
 4var imageExtractorOptions = new ImageExtractorOptions();
 5
 6// Add the input file path
 7imageExtractorOptions.AddInput(new FileDataSource(Path.Combine(@"C:\Samples\", "sample.pdf")));
 8
 9// Process the image extraction
10var resultContainer = plugin.Process(imageExtractorOptions);
11
12// Get the extracted image and save it to a file
13var extractedImage = resultContainer.ResultCollection[0].ToStream();
14var outputStream = File.OpenWrite(@"C:\Samples\tmp.jpg");
15extractedImage.CopyTo(outputStream);

Extracting Images from Multiple PDF Files

The ImageExtractor plugin supports batch processing, allowing you to extract images from multiple PDFs simultaneously. This feature is especially useful when you have a collection of PDF files and need to retrieve all the images in one go.

 4// Add multiple input PDF files
 5options.AddInput(new FileDataSource(@"C:\Samples\file1.pdf"));
 6options.AddInput(new FileDataSource(@"C:\Samples\file2.pdf"));
 7options.AddInput(new FileDataSource(@"C:\Samples\file3.pdf"));
 8
 9// Process the image extraction
10var resultContainer = plugin.Process(options);
11
12// Save the extracted images from all files
13for (int i = 0; i < resultContainer.ResultCollection.Count; i++)
14{
15    var extractedImage = resultContainer.ResultCollection[i].ToStream();
16    using var outputStream = File.OpenWrite($@"C:\Samples\image_{i + 1}.jpg");
17    extractedImage.CopyTo(outputStream);
18}
