I am trying to convert this code from java to C# (located here)
I have some winform experience but not a lot with the drawing of pixels on a winform applications.
I feel fairly confident I can convert over most of the sub methods im just unclear on how i would draw indiviual pixels on the screen
any help or tools for converting over java to c# would be greatly apprehsated
