"Pixel art" is typically drawn without any blending or bi-linear filtering. For legacy Direct3D 9, you'd use (assuming your textures are bound to slot 0):

device->SetSamplerState(0, D3DSAMP_MINFILTER, D3DTEXF_POINT);
device->SetSamplerState(0, D3DSAMP_MAGFILTER, D3DTEXF_POINT);
device->SetSamplerState(0, D3DSAMP_MIPFILTER, D3DTEXF_NONE);

At this point, you shouldn't use legacy Direct3D 9 at all. Direct3D 11 is your best bet. If you are using C++, take a look at the SpriteBatch class with the CommonStates::PointClamp() sampler state in the DirectX Tool Kit.
