Texture generator, Python Per Pixel (C#, IronPython, Python)

Step 0.

You can see previous C# texture generator code :
https://gameenginebread.blogspot.com/2017/02/this-is-c-code-to-generate-custom.html

It was a code-based tools and only available to programmers. Python is one of the best script for everyone.
So let's create the tool again simply with Python.


Step 1.

Create a new C# project.

Download 'iron python' and add DLLs to references.

IronPython :
http://ironpython.net

How to setup :
MSDN : Running IronPython scripts from a c#

Step 2.

Add controls. I have not changed the button name, but it will be understood.

Step 3.

This is the code.
