Extract images from document Leave feedback

GroupDocs.Parser provides the functionality to extract images from documents by the getImages() method:

parser.getImages() // returns Iterable<PageImageArea> or null

This method returns a Java Iterable collection of PageImageArea objects:

The ImageOptions class is used to define the image format into which the image is converted. The following image formats (ImageFormat) are supported:

• Bmp
• Gif
• Jpeg
• Png
• WebP

Here are the steps to extract images from the whole document:

• Instantiate the Parser object for the initial document;
• Call the getImages() method and obtain the collection of PageImageArea objects;
• Check if the collection isn’t null (images extraction is supported for the document);
• Iterate through the collection and get sizes, image types and image contents.

The following example shows how to extract all images from the whole document:

const groupdocs = require('@groupdocs/groupdocs.parser');

// Create an instance of Parser class
const parser = new groupdocs.Parser('images.pdf');
try {
  // Extract images
  const images = parser.getImages();
  // Check if images extraction is supported
  if (images == null) {
    console.log("Images extraction isn't supported");
  } else {
    // Iterate over images
    const it = images.iterator();
    while (it.hasNext()) {
      const image = it.next();
      // Print a page index, rectangle and image type
      console.log(`Page: ${image.getPage().getIndex()}, R: ${image.getRectangle()}, Type: ${image.getFileType()}`);
    }
  }
} finally {
  parser.close();
}
process.exit(0);

The output for images.pdf starts with:

Page: 0, R: (342.3999938964844; 233.83001708984375) (247.9499969482422; 164.8800048828125), Type: JPEG Image (.jpeg)
Page: 0, R: (342.3599853515625; 244.08001708984375) (248.0399932861328; 6.71999979019165), Type: JPEG Image (.jpeg)
