this adds 2 comfyui nodes

ImageTransformNode, which accepts an offsetX an offsetY and a zoom factor, and applies these transformations to the image it receives. This is useful for creating parallax effects, or for zooming in on a specific part of the image.

JsonParserNode which accepts a json string formatted like: { 'offsetX': 0, 'offsetY': 0, 'zoom': 0.5 }

and returns the 3 values as separate outputs. This is useful for creating a UI that allows the user to control the ImageTransformNode.
