/prog/ - SDL question

Name: Anonymous 2012-09-29 14:54

I'm learning SDL right now.
What are the advantages of color keying? Isn't it better to use transparent PNGs instead? It's easier and you can even have semi-transparency.

It's probably either quicker or not.

It's useful for pixelart graphics and takes less bandwidth.

It probably is. I wonder how much quicker though.
Will I run into problems when trying to move around 100+ animated sprites? Actually, I guess I'll just try.

Lower filesizes. You have one less channel because you're just using eye burning pink instead of alpha.

It doesn't require an alpha channel. I doubt there's any noticeable difference in speed.

Hm, okay. Thanks. So if I don't care about some extra kilobytes, using transparent PNGs is fine.

Last I checked, SDL didn't support transparency.

Sure. And I could be wrong on this, but you might need to set it to a different color mode that supports alpha transparency. If you only need "binary" transparency (opaque or transparent) color keying may be faster and use less memory.

SDL is perfectly fine for small projects.
