Members

Blt

A UINT value that specifies whether to bit-block transfer (bitblt) data to the primary surface. This bit-field flag can be used with the DstRectValid and SrcRectValid bit-field flags.

Setting this member is equivalent to setting the first bit of the 32-bit Value member (0x00000001).

ColorFill

A UINT value that specifies whether to perform a colorfill bitblt to the primary surface by using the value in the Color member of the D3DKMT_PRESENT structure. This bit-field flag can be used with the DstRectValid bit-field flag.

Setting this member is equivalent to setting the second bit of the 32-bit Value member (0x00000002).

Flip

A UINT value that specifies whether to flip to a new surface.

Setting this member is equivalent to setting the third bit of the 32-bit Value member (0x00000004).

FlipDoNotFlip

A UINT value that specifies whether to insert queued waits into the rendering stream. Setting this member indicates to flip to the same surface that is currently being scanned out.

Setting this member is equivalent to setting the fourth bit of the 32-bit Value member (0x00000008).

FlipDoNotWait

A UINT value that specifies whether the OpenGL installable client driver (ICD) requires that the present operation wait for the number of queued flip surfaces to fall below a particular limit before the operation begins. Setting this member indicates that the ICD does not require waiting. The default limit for the number of queued flip surfaces is three.

Setting this member is equivalent to setting the fifth bit of the 32-bit Value member (0x00000010).

FlipRestart

A UINT value that specifies whether to restart a flip to a new surface.

Setting this member is equivalent to setting the sixth bit of the 32-bit Value member (0x00000020).

DstRectValid

A UINT value that specifies whether the bitblt uses a destination rectangular area.

Setting this member is equivalent to setting the seventh bit of the 32-bit Value member (0x00000040).

SrcRectValid

A UINT value that specifies whether the bitblt uses a source rectangular area.

Setting this member is equivalent to setting the eighth bit of the 32-bit Value member (0x00000080).

RestrictVidPnSource

A UINT value that specifies whether to restrict the bitblt. If the hWindow member is NULL, the VidPnSourceId member of the D3DKMT_PRESENT structure indicates which output the full-screen bitblt is directed to; if hWindow is non-NULL, VidPnSourceId indicates which output to restrict the windowed bitblt to.

Setting this member is equivalent to setting the ninth bit of the 32-bit Value member (0x00000100).

SrcColorKey

A UINT value that specifies whether to perform source color-keying by using the value in the Color member of the D3DKMT_PRESENT structure. That is, any pixel in the source surface that matches the color key should not be copied to the destination surface, and all of the source pixels that do not match the color key should be copied.

Setting this member is equivalent to setting the tenth bit of the 32-bit Value member (0x00000200).

DstColorKey

A UINT value that specifies whether to perform destination color-keying by using the value in the Color member of D3DKMT_PRESENT. That is, any pixel in the destination surface that matches the color key should be replaced with the corresponding pixel from the source surface, and all of the destination pixels that do not match the color key should not be replaced.

Setting this member is equivalent to setting the eleventh bit of the 32-bit Value member (0x00000400).

LinearToSrgb

A UINT value that specifies whether to convert the linear-formatted source to sRGB format during the copy operation. sRGB format is gamma corrected. For more information about sRGB format, see the sRGB website.

Setting this member is equivalent to setting the twelfth bit of the 32-bit Value member (0x00000800).

PresentCountValid

A UINT value that specifies whether the value set in the PresentCount member of the D3DKMT_PRESENT structure is valid.

Setting this member is equivalent to setting the thirteenth bit of the 32-bit Value member (0x00001000).

Rotate

[in] A UINT value that specifies whether to rotate the presentation data to match the current orientation of the screen during the presentation bit-block transfer (bitblt). The current orientation of the screen is set in the Rotation member of a D3DKMDT_VIDPN_PRESENT_PATH_TRANSFORMATION structure, which is set in the ContentTransformation member of the D3DKMDT_VIDPN_PRESENT_PATH structure for the video present path.

The display miniport driver should rotate the data only if the Rotate bit-field flag is set. Even if the driver determines that the current orientation of the screen is rotated from the presentation data and Rotate is not set, the driver should not rotate the data.

Setting this member is equivalent to setting the fourteenth bit of the 32-bit Value member (0x00002000).

PresentToBitmap

A UINT value that specifies whether to present to a bitmap.

Setting this member is equivalent to setting the fifteenth bit of the 32-bit Value member (0x00004000).

Supported starting with Windows 7.

RedirectedFlip

A UINT value that specifies whether to redirect a flip to a new surface.

Setting this member is equivalent to setting the sixteenth bit of the 32-bit Value member (0x00008000).

Supported starting with Windows 7.

RedirectedBlt

A UINT value that specifies whether to redirect a bitblt to a new surface.

Setting this member is equivalent to setting the seventeenth bit of the 32-bit Value member (0x00010000).

Supported starting with Windows 7.

FlipStereo

Specifies whether the driver should flip both left and right images of a stereo allocation.

If the FlipOnNextVSync member of the DXGK_SETVIDPNSOURCEADDRESS_FLAGS structure is set, the driver should complete the flip to the left image on the next VSync and then complete the flip to the right image on the following VSync.

If the FlipImmediate member of the DXGK_SETVIDPNSOURCEADDRESS_FLAGS structure is set, the driver should immediately start to scan out from the new allocation. For example, if the driver was scanning a right image, it should start the new scan from the same relative offset in the right image of the new allocation.

The FlipStereo and FlipStereoTemporaryMono members cannot both be set at the same time.

For more requirements, see the Remarks section.

Setting this member is equivalent to setting the eighteenth bit of the 32-bit Value member (0x00020000).

Supported starting with Windows 8.

FlipStereoTemporaryMono

Specifies whether the driver should use the left image of a stereo allocation for the right and left portions of a stereo frame. The driver performs the same present operation as with FlipStereo, except that it should scan out only from the left image to produce both images of a stereo frame.

This member should be set only if the driver reports support for this option in the current display mode by setting the Type member of the D3DKMDT_VIDPN_SOURCE_MODE structure to D3DKMDT_RMT_GRAPHICS_STEREO_ADVANCED_SCAN.

The FlipStereo and FlipStereoTemporaryMono members cannot both be set at the same time.

The FlipStereoTemporaryMono and FlipStereoPreferRight members cannot both be set at the same time.

For more requirements, see the Remarks section.

Setting this member is equivalent to setting the nineteenth bit of the 32-bit Value member (0x00040000).

Supported starting with Windows 8.

FlipStereoPreferRight

Specifies that when the driver clones a stereo primary allocation to a mono monitor, it should use the right image.

The FlipStereoTemporaryMono and FlipStereoPreferRight members cannot both be set at the same time.

For more requirements, see the Remarks section.

Setting this member is equivalent to setting the twentieth bit of the 32-bit Value member (0x00080000).

Supported starting with Windows 8.

BltStereoUseRight

Specifies that when the driver presents from a stereo allocation to a mono allocation, it should use the right image. If not set, the driver should use the left image.

Setting this member is equivalent to setting the twenty-first bit of the 32-bit Value member (0x00100000).

Supported starting with Windows 8.

PresentHistoryTokenOnly

Specifies that the driver should submit only a present history token.

A present history token is a data packet that the rendering app submits to inform the Desktop Window Manager (DWM) that rendering is complete and the swap chain back buffer is ready to be presented.

Setting this member is equivalent to setting the twenty-second bit of the 32-bit Value member (0x00200000).

Supported starting with Windows 8.

PresentRegionsValid

Specifies that the D3DKMT_PRESENT.pPresentRegions member is a valid pointer (not NULL).

Setting this member is equivalent to setting the twenty-third bit of the 32-bit Value member (0x00400000).

Supported starting with Windows 8.

PresentDDA

This member is reserved and should be set to zero.

Setting this member is equivalent to setting the twenty-fourth bit of the 32-bit Value member (0x00800000).

ProtectedContentBlankedOut

This member is reserved and should be set to zero.

Setting this member is equivalent to setting the twenty-fifth bit of the 32-bit Value member (0x01000000).

Supported starting with Windows 8.

RemoteSession

Specifies that the present operation is directed to a remote session.

Setting this member is equivalent to setting the twenty-sixth bit of the 32-bit Value member (0x02000000).

Supported starting with Windows 8.

Reserved

This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting the remaining 6 bits (0xFC000000) of the 32-bit Value member to zeros.

Supported starting with Windows 8.

Reserved

This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting the remaining 9 bits (0xFF800000) of the 32-bit Value member to zeros.

Value

A 32-bit value that identifies how to perform the present operation.

Remarks

If any of the FlipStereo, FlipStereoTemporaryMono, or FlipStereoPreferRight members are set, these conditions apply:
