This enumeration is available only when developing for Windows.
Defines modes describing how to filter an image or mipmap when it is minified or magnified to fit a set of vertices.

Syntax
[FlagsAttribute]
public enum FilterOptions
Members
| Member name | Description | |
|---|---|---|
| Box | Each pixel is computed by averaging a 2×2(×2) 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. | |
| Dither | Resulting image must be dithered using a 4×4 ordered dither algorithm. This happens when converting from one format to another. | |
| DitherDiffusion | Do diffuse dithering on the image when changing from one format to another. | |
| Linear | Bilinear interpolation filtering is used as a texture magnification or minification filter. A weighted average of a 2×2 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, MirrorV, and MirrorW 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. | |
| MirrorW | Pixels off the edge of the texture on the w-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. | |
| Srgb | Same as specifying SrgbIn | SrgbOut. | |
| SrgbIn | Input data is in sRGB (gamma 2.2) color space. | |
| SrgbOut | Output data is in sRGB (gamma 2.2) color space. | |
| Triangle | Each pixel in the source image contributes equally to the destination image. This is the slowest of the filters. |
Remarks
Each valid filter must contain exactly one of the following flags: None, Point, Linear, Triangle, 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, MirrorV, MirrorW, Mirror, or Dither.
