RotSprite - better pixel art rotation

[worstplayer]

There was recently some discussion here about rotating pixel art, reached conclusion that it's not possible, and guess what I just found:
RotSprite
...and it works really well.
You still need to do some manual cleanup, but it's way better than rotation in other apps, which fucks up sprites beyond any repairs.

Incredible!

I've tried it as I'm currently in a major up-scale phase of my sprites and guess what, the result is astonishing:



THANKS!!!

Nice tip, thanks. Now only if I could get the source code and make it generate the rotate sprites at runtime. :P

I can't find source either, but here's a high level overview

TL;DR: expanding sprite with Scale2x to 8 times the original size, rotating it, shrinking it again, and replacing flat areas of wrong color with "dumb" rotation.

Doesn't sound like something you'd want to do in realtime. Maybe if you stored sprites in already expanded form...but then it'd take up as much memory as just using prerendered rotations.

That's what I meant, it would save on having to store dozens of extra .png files for no paticular reason. Only have to generate them once at run-time.

Oh wow. The results of this are absolutely great!
Rotation is almost flawless, but scaling is noticeably off [but still looks better than a doing just a straight hq2x filter [and it does arbitrary sizes, yay]].

This is easily one of the coolest little tools I've seen, shame there's no Linux version, it dies in Wine on the actual conversion step, had to run it in a VM.
