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.
