Dynamic image composition in C#

This project is to reproduce the same functionality as found in the python code here (see the last example for multiple image composition): [login to view URL] But I need it In C# - with a bit of extra added functionality: 1. Instead of functions with just a single variable consisting of a number e.g. x = 5, the input variable will be an image. 2. There should be functions with 1,or 2 variables. This means that image functions with 2 variables will need to input images e.g. add(X,Y) needs images X and Y. 3. There should be a method that picks the functions randomly, but of course any time a 2-variable function is picked, it needs to have two functions to operate on so a 2 variable function should be able to be picked unless there are at least two inputs. So there should be a list of functions [...,4,3,2,1] which operates on some initial image x, so [...4,3,2,1](x) = [...4,3,2,1(x)]. But if function 2 is a single variable function then function 2 takes in the output of function 1 i.e. 2(1(x)) etc. But to consider the two variable functions, consider Addition using a numerical example: Add(a,b): return a + b f(y): return x + 5 g(x): return x * 3 Say we have the list of functions [Add,f,g](y) where y is the input. The list should compute from right to left e.g. first g(y) is computed then the function f applied to that which means that f(g(y)). Then Add is applied to these two functions which gives Add(f(g(y)),(g(y))) So numerically: Add(a,b)(5) = [Add,f,g](5) = Add(f(g(5)),g(5)) where g(5) = 5*3 = 15 and so f(15) = 15 + 5 = 20, so we have Add(20,15) = 35. This is only the first part of something I'm trying to build (No, it is not homework) so there is potential for extending this piece of code.
