Extract images from documents Leave feedback

GroupDocs.Parser allows to extract images from PDF, Emails, Ebooks, Microsoft Office: Word (DOC, DOCX), PowerPoint (PPT, PPTX), Excel (XLS, XLSX), LibreOffice formats and many others (see the full list in the supported document formats article).

GroupDocs.Parser allows to easily implement both simple and complex image extraction cases (see more in the working with images section).

In this article you can see how to extract images from any supported format without additional settings.

To extract images from documents simply call the getImages() method:

parser.getImages(); // returns a Java Iterable of PageImageArea objects or null

This method returns a collection of PageImageArea objects:

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 image objects;
• Check if collection isn’t null (image extraction is supported for the document);
• Iterate through the collection and get sizes, image types and image contents.

The collection is a Java Iterable, so iterate over it with iterator(), hasNext() and next().

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().toString()}, Type: ${image.getFileType().toString()}`);
    }
  }
} finally {
  parser.close();
}

process.exit(0);
