How to get image DPI?

I'm using ImageObject to load an image to drawBot, process it through some filters and then save it as a new image. Simple batch processing.
Everything goes well when the images i input are 72dpi.
If the input image is set to more than 72dpi then saved images is smaller (in absolute px value).
I noticed there's an option to specify imageResolution for the saveImage() function so i'm assuming that i would need to match the dpi of the input and output image to keep the right size.
But how can i get the input image dpi?
in drawBot there is not a api for this.
I could consider
imageResoltion(path)returning the dpi
