Converting Normalized Vertex to Vertex in Google Cloud Vision

Question

Any idea how can I convert Normalized Vertex to Vertex? Normalized Vertex gives me relative position on an image whereas the Vertex returns coordinates based on the scale of the image. I have a set of Normalized Vertex that I would like to convert it to regular Vertex.

If you know the size of your image (it's width and height), you can simply multiply it with your NorrmalizedVertex. You should multiply the x field of your NormalizedVertex with the width of the picture to get the x field of the Vertex and multiply the y field of your NormalizedVertex with the height of the image to get the y of the Vertex.
