Regrid one 2d matrix to another of different dimensions

This request is clear and relevant.

I have a 2d grid that maps motion detection zones onto a camera image.

Let's say the grid is 80x45, and in this grid are mapped 4 different zones (A,B,C,D).

I need to remap multiple areas within a 2d grid to another 2d grid.

I want to re-size the 4 zones from this original grid (80x45) to new grids (say 64x36 or 160x90), so that zones retain their shapes relative to each other.

    Can we please see some test data showing the "before-and-after" we want to get? Thanks!

      I have images to share, but am unable to include them or provide links in this reply box. Can you suggest an alternative - perhaps I could send them by email?

I do not recall seeing a package that does exactly that of "regriding" another package.

What you can do is to take a package like this one that is recommending and improve it or suggest improvements to the author, so it can do what you need.
