Description
Box
5
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.
Point
2
Each destination pixel is computed by sampling the nearest pixel from the source image.
Srgb
6291456
Same as specifying SrgbIn | SrgbOut.
SrgbOut
4194304
Output data is in sRGB (gamma 2.2) color space.
SrgbIn
2097152
Input data is in sRGB (gamma 2.2) color space.
DitherDiffusion
1048576
Resulting image must be dithered using a 4x4 ordered dither algorithm.
Dither
524288
Resulting image must be dithered using a 4x4 ordered dither algorithm.
Mirror
458752
Same as specifying the MirrorU, MirrorV, and MirrorW flags. This flag is always used internally for this function.
MirrorW
262144
Pixels off the edge of the texture on the w-axis should be mirrored, not wrapped.
MirrorV
131072
Pixels off the edge of the texture on the v-axis should be mirrored, not wrapped.
MirrorU
65536
Pixels off the edge of the texture on the u-axis should be mirrored, not wrapped.
Triangle
4
Each pixel in the source image contributes equally to the destination image. This is the slowest of the filters.
Linear
3
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.
None
1
Mipmapping disabled. The rasterizer uses the magnification filter instead.
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.
