Extract Images from PDF C#

Images are held in each page’s Resources collection’s Images collection. To extract a particular page, then get the image from the Images collection using the particular index of the image.

The image’s index returns an XImage object. This object provides a Save method which can be used to save the extracted image. The following code snippet shows how to extract images from a PDF file.

The following code snippet also work with Aspose.PDF.Drawing library.

private static void ExtractImagesFromPDF()
{
    // For complete examples and data files, please go to https://github.com/aspose-pdf/Aspose.PDF-for-.NET
    // The path to the documents directory.
    string dataDir = RunExamples.GetDataDir_AsposePdf_WorkingDocuments();

    // Open document using 'using' block to ensure proper disposal
    using (var document = new Aspose.Pdf.Document(dataDir + "ExtractImages.pdf"))
    {
        // Extract a particular image
        var xImage = document.Pages[1].Resources.Images[1];

        using (var outputImage = new FileStream(dataDir + "outputImage.jpg", FileMode.Create))
        {
            // Save output image
            xImage.Save(outputImage, ImageFormat.Jpeg);
        }

        // Save updated PDF file
        document.Save(dataDir + "ExtractImages_out.pdf");
    }
}
