You’ll need to do it manually, by examining the pixels in the surface
and then skipping (or combining, if you don’t want it to look ugly) pixels.

Look for the ‘getpixel()’ and ‘putpixel()’ example code in the tutorials.

Or, you can use an add-on library that does this for you.
One that comes to mind (though I’m not sure if it’s deprecated, or not)
is SDL_rotozoom. (I’ve never personally used it.)

Search in the SDL website “Libraries” download page.

Good luck!

Hello Ricardo, (where are you in Brazil?)

Try one library, SDL Graphics (I think), it allows zoomin, rotating and scalling images on software surface, with support for MMX and 3D Now on the latest version, if I’m not wrong.

You can search for it at the SDL libraries page.
