Fields

Linear	1	Interpolate a color from the four bitmap pixels that are the nearest to the current rendering pixel.
MagLinearMinLinearMipLinear	2	Use Linear interpolation for magnification, minification, and mip-level sampling.
MagLinearMinLinearMipNearest	3	Use Linear interpolation for magnification and minification; use NearestNeighbor for mip-level sampling.
MagLinearMinNearestMipLinear	4	Use Linear interpolation for magnification; use NearestNeighbor for minification; use Linear interpolation for mip-level sampling.
MagLinearMinNearestMipNearest	5	Use Linear interpolation for magnification; use NearestNeighbor for minification and mip-level sampling.
MagNearestMinLinearMipLinear	6	Use NearestNeighbor for magnification; use Linear interpolation for minification and mip-level sampling.
MagNearestMinLinearMipNearest	7	Use NearestNeighbor for magnification; use Linear interpolation for minification; use NearestNeighbor for mip-level sampling.
MagNearestMinNearestMipLinear	8	Use NearestNeighbor for magnification and minification; use Linear interpolation for mip-level sampling.
MagNearestMinNearestMipNearest	9	Use NearestNeighbor for magnification, minification, and mip-level sampling.
NearestNeighbor	0	Use the exact color of the nearest bitmap pixel to the current rendering pixel.

Remarks

Interpolating pixels is necessary when the pixels of an ICompositionSurface do not form a one-to-one mapping to the pixels of a SpriteVisual; this can happen under scale, stretch, rotation, skew, or other transformations (such as perspective projection, etc.).

When the bitmap contents of an ICompositionSurface are mapped to a SpriteVisual whose size is larger than that of the bitmap, each pixel from the surface must be mapped to a group of pixels on screen.

Conversely, when the bitmap contents of an ICompositionSurface are mapped to a SpriteVisual whose size is smaller than that of the bitmap, multiple pixels from the surface must be mapped to single pixels on screen.
