To extract and image from a page:

Get the image from the Images collection using the image index. Use the XImage object’s save(..) method to save the extracted image.

package com.aspose.pdf.examples;

import java.io.FileOutputStream;
import java.io.IOException;

import com.aspose.pdf.*;
import com.aspose.pdf.internal.html.rendering.image.ImageFormat;

public class ExampleExtractImages {

    private static String _dataDir = "/home/admin1/pdf-examples/Samples/";

    public static void ExtractImages() throws IOException {

        // Open document
        Document pdfDocument = new Document(_dataDir + "ExtractImages.pdf");

        // Extract a particular image
        XImage xImage = pdfDocument.getPages().get_Item(1).getResources().getImages().get_Item(1);

        FileOutputStream outputImage = new FileOutputStream(_dataDir + "output.jpg");

        // Save output image
        xImage.save(outputImage, ImageFormat.Jpeg);
        outputImage.close();

        // Save updated PDF file
        pdfDocument.save(_dataDir + "ExtractImages_out.pdf");
    }
