Image Scaling

Name: Anonymous 2012-08-22 16:07

/prog/, do you have fast and good image scaling algorithm in the form of:
void resample(uint8_t *Dst, int DstW, int DstH, uint8_t *Src, int SrcW, int SrcH);

???

The inner loop will be compiled as a pointer counting up towards an end pointer, basically: while (dstp < dst_end)
Only if compiler is very smart. IIRC, Visual Studio 6.0 havent done such optimization and since then I always do it manually.

It can be done by hand rather rapidly using bit operators.

To my knowledge GCC has featured this optimization since forever

What the hell does ``ishygddt" mean, friend?

By the way, why are ``2011" and ``micro-optimization" green? And if you were going to quote something, you do it with "> ", not with ">".

But I doubt you would want to quote ``2011" and ``micro-optimization", >>28-san didn't mention those words.

I'm truly confused.

No, really, I don't understand and I'd like to know.

I can't believe you're lazy enough to contract that sentence into a badly done ``acronym" that doesn't even use uppercase letters.

And how do you expect me to do a ``2011"?

It's already 2011 and you're still doing this?

What?

Please be honest, did this stupid contraction come from Reddit? Never seen it on /prog/ before.

It came from the imageboards, namely /v/. /sp/ will claim to have ``started it'' but nobody goes to /sp/ so there's no proof and it would have never reached popularity if it didn't spring up in /v/.

Gosh, so it came from the imageboards.

Why do these people think they're an ``epic meme factory"? This stupid contraction is not even funny.

Because the imageboards are all about xD TUH EPICKQ LOWELEZ, since it's all children and manchildren. However generally their tropes get used here satirically and provocateurally, because we hate most of each other.
