I don't mean to be rude but changing the display resolution does the opposite of what I'm going for ;; It might come in handy for another option though..
I meant I DO want to stretch the display when resizing the window, but I don't want the interpolation that comes with it. Basically my game's window width and height is 256x224. I just want to stretch the window out to 512x448 or higher so it's easier to see. I used the window object and "set size" to achieve this, but like I said it automatically messes with the graphics and makes them blurry. With that said, is there a way to resize the window and it's contents without distorting the graphics?
Sorry for any confusion.
You are not rude
Changing the display resolution does what you want (instead of resizing the window), you just need to rework the content to your needs (point sampling is still required, of course).
Your actual example as pseudo code:
+(Some trigger, eg On key pressed)
->System: Set layout size to 512x448
->System: Set zoom to (200, 200)
->System: Set display size to 512x448
The only thing left to do is reposition the "camera", but that's dependant of what you want to show or what other events or plugins you use therefore, so I'll leave it out.
