Hello,
I have a question:
can all the sprite on the screen be "filtered" smoothing the edge pixels and all?
like a Bilinear filter.

or like Runaway.

thanks

In 3D accelerated mode sprites gets automatically antialiased when scaled (characters for example). But to get sprites with antialiased edges the best approach is to use PNG images with an alpha channel.

Hello,
thanks for reply 
So, if I have an img with a circle, the edge of the circle will be directly antialiased?
I've seen the demo with the CG girl, and the edge does'nt  antialiased.

thanks

I guess you mean the 3d demo with the trinity character from matrix.
If yes then you have to enable antialiasing when running the executable. (2x, 4x or 6x antialiasing option available)

no I mean the 2d demo

The 2d demo is using bmp format for graphics which doesn't support alpha channel (like PNG).
That's why the edges are blocky. (It's an old demo afterall).

EDIT: And as I said earlier to get antialiased sprites use the png format with an alpha channel (tga format can also support alpha channel but png produces smaller files and it's more used anyway)

thanks for your usefull reply.

thanks!
