DXGI_DDI_PRESENT_FLAGS structure (dxgiddi.h)
Identifies how to perform a present operation.
Syntax
typedef struct DXGI_DDI_PRESENT_FLAGS {
union {
struct {
UINT Blt : 1;
UINT Flip : 1;
UINT PreferRight : 1;
UINT TemporaryMono : 1;
UINT AllowTearing : 1;
UINT AllowFlexibleRefresh : 1;
UINT NoScanoutTransform : 1;
UINT Reserved : 25;
};
UINT Value;
};
} DXGI_DDI_PRESENT_FLAGS;
Members
Blt
Specifies whether to perform a bit-block transfer (bitblt) data to the primary surface.
Setting this member is equivalent to setting the first bit of the 32-bit Value member (0x00000001).
Flip
Specifies whether to flip to a new surface.
Setting this member is equivalent to setting the second bit of the 32-bit Value member (0x00000002).
PreferRight
Supported in Windows 8 and later versions.
Specifies that, if a stereo present operation must be reduced to mono, the present operation should show the view from the right eye.
If this member is not set, the default mono present operation shows the view from the left eye.
Setting this member is equivalent to setting the third bit of the 32-bit Value member (0x00000004).
TemporaryMono
Supported in Windows 8 and later versions.
Specifies that a present operation should use the left buffer as a mono (non-stereo) buffer.
Setting this member is equivalent to setting the fourth bit of the 32-bit Value member (0x00000008).
AllowTearing
AllowFlexibleRefresh
NoScanoutTransform
Supported in Windows 10, version 1901 and later.
This flag will only be passed if the driver set the D3DWDDM2_6DDI_SCANOUT_FLAG_TRANSFORMATION_DESIRED flag, instead of the D3DWDDM2_6DDI_SCANOUT_FLAG_TRANSFORMATION_REQUIRED flag of the D3DWDDM2_6DDI_SCANOUT_FLAGS enumeration.
Reserved
This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting the remaining 28 bits (0xFFFFFFF0) of the 32-bit Value member to zeros.
Value
A member in the union that is contained in DXGI_DDI_PRESENT_FLAGS that can hold one 32-bit value that identifies how to perform a present operation.
