Is there anyone interested in a tutorial on pixel perfect upscale in Game Maker? I have tow version of it, one rendering an upscaled version of the view to a monitor size picture, and another one rendering an actual low res image, upscaled properly.
Apparently there is nothing up to date here, and I remember how it pissed me to fail at upscaling properly my pixel art when I started.

Im definitely interested. I have finally found a way to make it scale the low-res image to the highest even multiplier that the monitor can support... But i've got a feeling there are lots of room for improvement. One thing that bugs me is the camera-movement when the pixels are not split, when it's set to interpolate between, say, player and crosshair, i often get "camera-seizures" when it's closing in on it's focus point... There are some other issues that i can't remember right now of course...
But at least im interested

I would also really like to see one on some good looking parallax-backgrounds, for some reason i can't seem find any tutorials, or project-files, or own ways to make it work well. And it feels like it should be quite simple really, don't know why it doesn't work out

Oh, and if anyone could explain how to do this:
http://www.codeproject.com/Articles/106884/Implementing-Auto-tiling-Functionality-in-a-Tile-MI that would also be greatly appreciated by me at least... Maybe i've just been too tired every time i've read the article, but i can't figure out how the principle is supposed to be implemented.
<- lazy noob, but you may as well try to get it cheap, if no one feels up to explaining it i will brute force it into my brain somehow

I really should get some sleep first though
