Pixel-art scaling

[nkorth]

I got my pixel-art game to scale cleanly to higher resolutions, but I was wondering: has anyone implemented scaling algorithms like scale2x, 2xsai, or hq2x in Löve?

Actually, Mari0 (A project I'm sure you've heard about by now, go to stabyourself.net to check it out) has some PixelEffects files that do a bunch of cool stuff. One of them was HQ2X I believe. It's completely possible using Effects/Shaders and Canvases.

I'm not really keen in bumping old topics, but this is exactly what I wanted to ask about, so I'd rather post here.

I implemented such an algorythm (more precisely the Scale2X) in as3 for a game that I'd like now to port to LÖVE. It was relatively slow, so I never tried doing it with HQX because that is even more complex and requires more computations.

If anyone is interested, I can post the source for that, but I was wondering if someone did already implemented the HQX algorythm as a shader.

I have little experience with shaders, but I'll give it a go if no one else did. I suspect they are considerably faster than AS3 implementations, so then, worth implementing.

Indeed it does. Thanks!
