DCOMPOSITION_BITMAP_INTERPOLATION_MODE enumeration (dcomptypes.h)
Specifies the interpolation mode to be used when a bitmap is composed with any transform where the pixels in the bitmap don't line up exactly one-to-one with pixels on screen.
Syntax
typedef enum DCOMPOSITION_BITMAP_INTERPOLATION_MODE {
DCOMPOSITION_BITMAP_INTERPOLATION_MODE_NEAREST_NEIGHBOR = 0,
DCOMPOSITION_BITMAP_INTERPOLATION_MODE_LINEAR = 1,
DCOMPOSITION_BITMAP_INTERPOLATION_MODE_INHERIT = 0xffffffff
} ;
Constants
DCOMPOSITION_BITMAP_INTERPOLATION_MODE_NEAREST_NEIGHBOR Value: 0 Bitmaps are interpolated by using nearest-neighbor sampling. |
DCOMPOSITION_BITMAP_INTERPOLATION_MODE_LINEAR Value: 1 Bitmaps are interpolated by using linear sampling. |
DCOMPOSITION_BITMAP_INTERPOLATION_MODE_INHERIT Value: 0xffffffff Bitmaps are interpolated according to the mode established by the parent visual. |
Remarks
The default interpolation mode for a visual is DCOMPOSITION_BITMAP_INTERPOLATION_MODE_INHERIT. If all visuals in a visual tree specify this mode, the default for all visuals is nearest neighbor sampling, which is the fastest mode.
A single visual can have any combination of visual properties. However, if a visual has the following combination of properties, the borders of the visual will default to DCOMPOSITION_BORDER_MODE_HARD.
