add_mez_image_watermark

Add an image overlay watermark to an existing ABR Mezzanine content object, optionally creating a new offering based on an existing one.

For best results, use an image in PNG format with a transparent background.

Before running, set env var PRIVATE_KEY

(substitute appropriate PRIVATE_KEY below)

npm install

export PRIVATE_KEY=0x0000000000000000000000000000000000000000000000000000000000000000

Example contents for WatermarkJsonFile (uploading local image file to mezzanine - file should be in same directory as the watermark json file):

{
  "align_h": "right",
  "align_v": "bottom",
  "image": "./logo.png",
  "margin_h": "1/20",
  "margin_v": "1/10",
  "target_video_height": 1080
}

---

Example contents for WatermarkJsonFile (using an image that has already been uploaded to fabric):

{
  "align_h": "right",
  "align_v": "bottom",
  "image": "/qfab/hq__C8vZUxtSdiW1zBKQWbUZVL6ZK3qctmiMVQ2XsQDfP3jqwQ2upKGPcg3DBd5dheMbepBrTDTLWi/files/watermark.png",
  "margin_h": "1/20",
  "margin_v": "1/10",
  "target_video_height": 1080
}

The image property in this case would refer to the hash of the object containing the image file.
