Bitmap rotation...?

SDL Development

Hi,
I was just wondering if SDL supports bitmap/image rotation, and if it doesn’t
would it be possible to rotate SDL_Surface(s) manually?

-Thanks

is it possible to rotate it manualy? yes, everythings possible of course :stuck_out_tongue:

but!

check out SDL_Rotozoom from the libraries Section on the sdl page, it might
be what your looking for.

or you could learn opengl and use it for 2d.> ----- Original Message -----

Hi,

libSDL itself does not.

Of course. And it’s been done! There are even libraries that you can
drop in and use. :^) SDL_gfx, for example, includes a rotozoomer:

http://www.ferzkopp.net/~aschiffler/Software/SDL_gfx-2.0/

Not sure if that’s the latest, greatest lib that can do this for you,
but it’s the one I always remember. (I personally haven’t used it myself,
yet!)

For more on doing it yourself, look up the ‘getpixel()’ and 'putpixel()'
example functions, somewhere in the example code and/or docs.

Good luck!
