2xSaI

[konjak]

I was just wondering if MMF2 today would allow for a feature such as 2xSai to be implemented? It's used in some emulators and what it does is it doubles the screen size and makes it look smooth. I'm no programmer, but it would be great if it was ever done as an extension or something. It's a CPU-heavy procedure though, I would think.

That's the link to the creator's site. It could be useful for, you know, lazy game-makers who want to make games in small resolutions... <img src="/center/images/graemlins/wink.gif" alt="" />

Isn't the resize to screensize exactly what you mention here?

I've seen this before (I think someone had a go at making this effect in Jamagic or something like that)

If the engine is open-source (which I think it is) there's no reason why it couldn't be made an extension. But it would need to zoom in on half the screen size, so if you wanted a 640x480 screen showing a resized 320x240 game, you would need to have the zoom object 640x480 in size and the rest of the level 320x240 behind it and in the middle of the screen. This would get more complicated with scrolling too...

I would also appreciate such an extension.

Zoom Object? wouldnt ViewPort be much easier to work with?

it has nothing to do with zoom or viewport, it makes the image clearer using an enlargement equation

[MrCyberpunk]

could it be used to make a better quality version of the zoom object and viewport object? That'd be cool, because i've found that the Zoom Object is overly pixelated.. to be expected i suppose but this would be GREAT!

If anyone feels like making an extension.. Here's the source

I'd love to have 2xSaI implented. Interesting to see that it's open source, I actually always believed until now that it was a feature that was built into the graphics card.

In either case, it would actually be extremely useful.

Sounds alot like Scale2x, which uses a simple algorithm to guess pixels to make images clearer. It can also scale further to make images up to 4 times bigger iirc.

I'd rather have this implemented into the Resize display to fill window size option. You know, non-integer pixel resizing looks rather ugly. Also, there's a newer filter called HQ2X (along with 3X, 4. That's also used in many emulators. You can find it and its source here:

In addition, many emulators interpolate the pixels when the display is stretched to fit. I think a few emulators out there actually interpolate the pixels that HQ2X doesn't filter, which makes the image look pretty good and not pixellated.
