| 定数名 | 解説 |
| None | 「MipMapは無効になり、ラスタライザはかわりにMagFilterを使います。」だそうです。 |
| Point | 滑らかになりません。一番近いテクセルの色が使われます。ギザギザです。 |
| Linear | バイリニアフィルターです。周りの2x2の領域の中での平均値が使われます。いろんなサンプルを見たところ、これが一番使われているようですね。 |
| Anisotropic | 異方性フィルターです。 |
| PyramidalQuad | 4サンプル・テントフィルターです。 |
| GaussianQuad | 4サンプル・ガウシアンフィルターです。画像をぼかすことで滑らかにするそうです。 |
