First I'm not a Programmer To Know how to make it but I'm Designer i can't Imagine the idea As A programmer But i will Say It.
I have an solution for stretching pixels and make the size of the picture bigger without making pixels get bad .
what about making of each pixel 8 copies around it then we will have 9 pixels make a a new square of 9 pixels and when we want to have a new size bigger than size we can make more pixels,
as example if we want to make the picture Bigger 200% we will make 8 Copies around one pixel to Have 9 pixels it's okay , then when we want to make the picture 300% we will make around the new 9 pixels we will make 12 pixels all Will Be the same pixel But There will Be a problem when we make 8 copies we will make the picture 800% bigger so We Can Get the Picture bigger as we like and then we will make photoshop resize the picture again to the size we want to have . so Instead of stretch one pixel we make Copies of that pixel to make the size of the picture bigger and not to make it bad.

Set the interpolation to Nearest Neighbor.

What you described is 300%, not 200% enlargement. 200% would create 2 pixels by 2 pixels (4 total).

For photographs, you would use the Bicubic interpolation methods to keep edges relatively smooth.

But for pixelated artwork where you don't want antialiasing, use Nearest Neighbor.
