Or vice versa.

If you have an image, you can get its dimensions with
getDimensions. Multiply these by your scaling factor.

What about vice versa? Divide these by dimensions?

If you know the scaling factor used to scale up the images while drawing, then you just divide the dimensions by the scaling factor, yeah. Of course, that assumes that you know the resulting drawn dimensions of the image. This is because getDimensions returns the dimensions of the texture, it won't give you the dimensions the image was last drawn with.

Ok, thanks
