Question

Pixels mapped onto an X-Y coordinate plane

Answer 1

Answer:

I put 2 images for an Example.

Your coordinates look odd, but going from co-ordinates to pixels, you probably want something like

f(x,y)=(190y+5,195−190x)

and going from pixels to coordinates

g(a,b)=(195−b190,a−5190,)

but you may need to adjust this slightly to deal with what happens on the edges
