title: How to combine image and text into one blob in google drive
body: <p>I'm trying to create my own barcode labels with google apps script.  I'm able to retrieve an image blob of the barcode, but I want to be able to add another row of text to it.  Is it possible to combine or edit the image blob?  If so how would one go about doing that.</p>
  
  <p>Here is my current code for getting the barcode.</p>
  
  <pre><code>function createLabel() {
    var url = "http://www.barcodesinc.com/generator/image.php?code=20-001-001&amp;style=196&amp;type=C128B&amp;width=200&amp;height=100&amp;xres=1&amp;font=3"
    var image = UrlFetchApp.fetch(url).getBlob();
    DriveApp.createFile(image);
  }
  </code></pre>
  
  <p>I know the barcode comes with the number of its data below it, but I need to make that number larger and easier to read.</p>
  
  <p>I've tried creating a document and inserting the text and image, but it's just printing like I need it to print.</p>
