IDirect3DDevice9, setting how textures scale?

In Photoshop you can control how pictures are scaled up and down as 'image interpolation', it has different options like 'Bicubic', 'Bilinear', 'Nearest Neighbour' and such.

I was wondering if I could do something similar in DirectX? Basically if I slap a texture on a quad and stretch the quad how can I control how the texture on the quad is represented?

Thanks for any help!

If you are using fixed function pipeline :

Setting the D3DSAMP_MAGFILTER, D3DSAMP_MINFILTER , D3DSAMP_MIPFILTER values.

Otherwise set the FILTER option of the sampler object if you're using HLSL.

There are 4 type of filtering. NONE, POINT, LINEAR, ANISOTROPIC.
