How do I intercept and alter touch events on a windows 10 tablet?

This is my first post on stackoverflow.
I have an old tablet with a faulty digitizer. The inputs are upside down, such that a tap in the lower right is registered in the upper left. Windows calibration does not fix it. I'd like to get this thing working right. More importantly, I'd like to use the opportunity to learn something.
I have some experience with C, C++, but mostly android apps in java. I've got no experience using hooks ad have never written a driver or driver filter before. I'm not sure that that is what I need to do. I was hoping to just write a background process that intercepts the touch input, inverts the x and y coordinates and then delivers that altered touch input to windows. I have only limited knowledge of windows applications, but I can review the basics elsewhere. My main question here is exactly what is in the title.
What do I need to do to read a touch input before it gets to windows, and how do I then send a touch event with the altered coordinates?
If you can't answer the question directly, but can point me in the right direction, please do.
If anyone has other suggestions for flipping the digitizer inputs, I'll welcome them, but either way I want to know how to do these things with software I can write and alter. Thank you for any and all help!
