Adding Dynamic Watermark with a pass-through field? | XM Community
Skip to main content

I'm trying to add dynamic watermarks to images in my survey, which would add a unique identifier (passed through the survey link) to all images.
I found this question but I haven't been able to get the watermark to work: https://community.qualtrics.com/XMcommunity/discussion/9316/display-a-dynamic-watermark-on-an-image.
In Look and Feel-->General-->Header, I added this as source code:
However, I'm not sure how to implement this JS to get the watermark to appear on my images. I tried adding it to the specific question under Edit Question JavaScript, but nothing happens :
$('img.watermark').watermark({
text: 'GOOGLE.COM',
textWidth: 100
});
What am I missing? What do I add to this above JS to reference my image?

Hi there, if you still need, I explored this a bit was able to get the watermarking to work. I found the code here:
https://brianium.github.io/watermarkjs/text.html
First, over in the survey's Look & Feel, add the below to the Header of the survey:






Next, over in the Builder, create a Text/Graphic question. Using the Rich Content Editor, configure the Question Text like the below:
Click here to write question text

 

Finally, add the below to the OnReady of the question's JS, updating the "Example Watermark" text and Image URL as needed:
watermark(['ImageURL'])
  .image(watermark.text.lowerRight('EXAMPLE WATERMARK', '48px Josefin Slab', '#fff', 0.5))
  .then(function (img) {
    document.getElementById('IMGID').appendChild(img);
  });

To make the Watermark text dynamic based off of an Embedded Data field, update the JS like the below:
var EMB = "${e://Field/EMB}";

watermark(m'ImageURL'])
  .image(watermark.text.lowerRight(EMB, '48px Josefin Slab', '#fff', 0.5))
  .then(function (img) {
    document.getElementById('IMGID').appendChild(img);
  });

Going to update this post since the migration is hiding some of it. 

I found the code here:

https://brianium.github.io/watermarkjs/text.html

First, over in the survey's Look & Feel, add the below to the Header of the survey:

<script src="https://brianium.github.io/watermarkjs/scripts/polyfill.js"></script>
<script src="https://brianium.github.io/watermarkjs/scripts/watermark.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/8.5/highlight.min.js"></script>
<link rel="stylesheet" href="https://brianium.github.io/watermarkjs/css/bootstrap.min.css">
<link rel="stylesheet" href="https://brianium.github.io/watermarkjs/css/bootstrap-theme.min.css">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/8.5/styles/default.min.css">

Next, over in the Builder, create a Text/Graphic question. Using the Rich Content Editor, configure the Question Text like the below:

Click here to write question text
<div id="IMGID">&nbsp;</div>

Finally, add the below to the OnReady of the question's JS, updating the "Example Watermark" text and Image URL as needed. I recommend using an image uploaded to your Qualtrics library.

setTimeout(function () { //ensure font faces are loaded

var text = watermark.text;

watermark(('https://yourbrand.az1.qualtrics.com/CP/Graphic.php?IM=IM_38Y8dGQPZMMQbMW'])
        .image(text.lowerRight('EXAMPLE WATERMARK', '100px Josefin Slab', '#fff', 0.5))
        .then(function (img) {
          var pre = document.querySelector('#IMGID');
          pre.parentNode.insertBefore(img, pre);
        });

}, 100);

 

To make the Watermark text dynamic based off of an Embedded Data field or question answer, update the JS like the below to include the piped text. In the below example, the piped text from an open ended question on a previous page is being used to set the watermark for the image.

setTimeout(function () { //ensure font faces are loaded

var EMB = "${q://QID35/ChoiceTextEntryValue}";

var text = watermark.text;

watermark(k'https://yourbrand.az1.qualtrics.com/CP/Graphic.php?IM=IM_38Y8dGQPZMMQbMW'])
        .image(text.lowerRight(EMB, '100px Josefin Slab', '#fff', 0.5))
        .then(function (img) {
          var pre = document.querySelector('#IMGID');
          pre.parentNode.insertBefore(img, pre);
        });

}, 100);
