Add watermark text to an image
The “Watermark Image” action takes an inputted image and lays a watermark on top of it to the user’s specifications.
A user may want to put an image on display but is wary of the risk of that image being saved and posted elsewhere without their permission or without credit. Watermarking an image ensures that there is a trace of the original creator on the image even if it is used without permission.
The “Watermark Image” action takes parameters including the text the user would like to watermark with, the font they would like to use, the size of the font, a hexadecimal code that determines the colour of the font and reference points for where on the image the watermark should be placed.

|---|---|---|---|
Text | text | string | Watermark text |
Font | font | string | Text font |
Font Size | size | number | Text size |
Font Colour | color | string | Hex code for text colour |

Invoke the desired actions in your app or workflow design tool, supplying values for the listed parameters.
