  6. Setup AEM to use the worker

Lesson 5: Set Up AEM to Use the Worker

Go to your AEM Cloud instance and open Tools -> Assets -> Processing Profiles. Then create a new processing profile, for example My Worker test profile. On the Custom tab, configure your renditions to use your worker, as shown here:

Config of custom renditions

These three renditions were created using imgix configuration parameters - we don't need to escape JSON, since it's used in AEM:

  1. Crop an image to 300x300 px around faces if detected, or around busy sections of the image (entropy):

    {
     "fit": "crop",
     "crop": "faces,entropy",
     "w": 300,
     "h": 300
    }
    
  2. Apply an ellipse mask around the cropped area in the previous rendition.

    {
     "fit": "crop",
     "crop": "faces,entropy",
     "w": 300,
     "h": 300,
     "fm": "png",
     "mask": "ellipse"
    }
    
  3. Add a text watermark to the rendition in the previous image:

    {
     "h": 300,
     "w": 300,
     "fit": "crop",
     "crop": "faces,entropy",
     "mark": "https://assets.imgix.net/~text?w=200&txt-color=fff&txt=Hello+world&txt-size=16&txt-lead=0&txt-pad=15&bg=80002228&txt-font=Avenir-Heavy"
    }
    

Finally, apply the profile to DAM folder:

Apply Profile to Folder

Now you can upload images to the folder and observe results on the asset details page.
