Search and Get Images from PDF Document

The ImagePlacementAbsorber allows you to search among images on all pages in a PDF document.

To search a whole document for images:

1. Call the Pages collection’s Accept method. The Accept method takes an ImagePlacementAbsorber object as a parameter. This returns a collection of ImagePlacement objects.
2. Loop through the ImagePlacements objects and get their properties (Image, dimensions, resolution and so on).

The following code snippet shows how to search a document for all its images.

package com.aspose.pdf.examples;

import java.io.IOException;
import com.aspose.pdf.*;

public class ExampleSearchAndGet {

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

    public static void SearchImages() throws IOException {
        // Open document
        Document doc = new Document(_dataDir + "SearchAndGetImages.pdf");

        // Create ImagePlacementAbsorber object to perform image placement search
        ImagePlacementAbsorber abs = new ImagePlacementAbsorber();

        // Accept the absorber for all the pages
        doc.getPages().accept(abs);

        // Loop through all ImagePlacements, get image and ImagePlacement Properties
        for (ImagePlacement imagePlacement : abs.getImagePlacements()) {
            // Get the image using ImagePlacement object
            // XImage image = imagePlacement.getImage();

            // Display image placement properties for all placements
            System.out.println("image width:" + imagePlacement.getRectangle().getWidth());
            System.out.println("image height:" + imagePlacement.getRectangle().getHeight());
            System.out.println("image LLX:" + imagePlacement.getRectangle().getLLX());
            System.out.println("image LLY:" + imagePlacement.getRectangle().getLLY());
            System.out.println("image horizontal resolution:" + imagePlacement.getResolution().getX());
            System.out.println("image vertical resolution:" + imagePlacement.getResolution().getY());
        }

    }
}

To get an image from an individual page, use the following code:

doc.getPages().get_Item(1).accept(abs)
