Members

	Member name	Description
	Box	Each pixel is computed by averaging a 2x2(x2) box of pixels from the source image. This filter works only when the dimensions of the destination are half those of the source, as is the case with mipmaps.
	Linear	Bilinear interpolation filtering is used as a texture magnification or minification filter. A weighted average of a 2x2 area of texels surrounding the desired pixel is used. The texture filter to use between mipmap levels is trilinear mipmap interpolation. The rasterizer interpolates pixel color in a linear manner, using the texels of the two nearest textures.
	Mirror	Same as specifying the MirrorU and MirrorV flags. This flag is always used internally for this function.
	MirrorU	Pixels off the edge of the texture on the u-axis should be mirrored, not wrapped.
	MirrorV	Pixels off the edge of the texture on the v-axis should be mirrored, not wrapped.
	None	Mipmapping disabled. The rasterizer uses the magnification filter instead.
	Point	Each destination pixel is computed by sampling the nearest pixel from the source image.

Remarks

Each valid filter must contain exactly one of the following flags: None, Point, Linear, or Box. In addition, the bitwise OR operator can be used to specify zero or more of the following optional flags with a valid filter: MirrorU or MirrorV, or Mirror.
