Details

The following pointers are thought of when doing the following calculations.

• The image is to be scaled without any distortions. No skews etc

• The translation coordinates of an image is defined by the top left corner of the image

• The following function will not query the Googleslides API to retrieve the page size automatically. The user would need to obtain that information and feed it into this function. This is to prevent this function from overutilizing the API unnecessarily when utilizing this function
