Java Words developers can easily insert an image into a DOCX document using the Aspose.Words Cloud REST API. This guide walks you through the process of adding a picture to a Word file online with the Java Low‑Code API, covering the key properties you can set to customize the image before it is placed in the document. For more details on the DOCX format, see the DOCX file information page. You can also use image files such as PNG as the source.

Steps to Add a Picture to Word Document with Java REST API

  1. Initialize the WordsApi object with your client ID and client secret.
  2. Create an InsertDrawingObjectOnlineRequest, providing the source Word file bytes and the desired output file name.
  3. Instantiate a DrawingObjectInsert object and configure the image’s characteristics (size, position, wrap type, etc.).
  4. Assign the target image file to the request object.
  5. Call the InsertDrawingObjectOnline method to insert the image into the Word document.
  6. Retrieve the resulting document from the response and save it using the Document.TryGetValue() method.

The steps above outline the complete workflow for adding a picture to a Word document via the Java REST API. By constructing the InsertDrawingObjectOnlineRequest with the appropriate parameters—input document, output name, image dimensions, placement, and image file—you can programmatically embed images into your Word files.
