DCOMPOSITION_BORDER_MODE enumeration (dcomptypes.h)
Specifies the border mode to use when composing a bitmap or applying a clip with any transform such that the edges of the bitmap or clip are not axis-aligned with integer coordinates.
Syntax
typedef enum DCOMPOSITION_BORDER_MODE {
DCOMPOSITION_BORDER_MODE_SOFT = 0,
DCOMPOSITION_BORDER_MODE_HARD = 1,
DCOMPOSITION_BORDER_MODE_INHERIT = 0xffffffff
} ;
Constants
DCOMPOSITION_BORDER_MODE_SOFT Value: 0 Bitmap and clip edges are antialiased. |
DCOMPOSITION_BORDER_MODE_HARD Value: 1 Bitmap and clip edges are aliased. See Remarks. |
DCOMPOSITION_BORDER_MODE_INHERIT Value: 0xffffffff Bitmap and clip edges are drawn according to the mode established by the parent visual. |
Remarks
The default border mode for any given visual is DCOMPOSITION_BORDER_MODE_INHERIT, which delegates the determination of the border mode to the parent visual. If all visuals in a visual tree specify this mode, the default for all visuals is aliased rendering, 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.
