Windows Driver Kit DDI reference (ns-dxgiddi-dxgi_ddi_multiplane_overlay_attributes)

DXGI_DDI_MULTIPLANE_OVERLAY_ATTRIBUTES structure

Description

Used by the user-mode display driver to specify overlay plane attributes.

Members

Flags

Specifies a flip operation as one of the applicable values in the DXGI_DDI_MULTIPLANE_OVERLAY_FLAGS enumeration.

SrcRect

Specifies the source rectangle, of type RECT, relative to the source resource.

DstRect

Specifies the destination rectangle, of type RECT, relative to the monitor resolution.

ClipRect

Specifies any additional clipping, of type RECT, relative to the DstRect rectangle, after the data has been stretched according to the values of SrcRect and DstRect.

The driver and hardware can use the ClipRect member to apply a common stretch factor as the clipping changes when an app occludes part of the DstRect destination rectangle.

Rotation

Specifies the clockwise rotation of the overlay plane, given as a value from the DXGI_DDI_MODE_ROTATION enumeration.

Blend

Specifies the blend mode that applies to this overlay plane and the plane beneath it, given as a value from the DXGI_DDI_MULTIPLANE_OVERLAY_BLEND enumeration.

DirtyRectCount

The number of dirty rectangles specified for the overlay plane. If zero, the entire plane is considered dirty.

pDirtyRects

A pointer to an array of dirty rectangles (RECTs), relative to the source rectangle SrcRect, that indicate the portion of the overlay plane that has changed.

The driver can use this member to perform optimizations, though it's not required to use the dirty rectangle info. However, the driver should never fail a function call based on the provided dirty rectangles.

NumFilters

Optionally specifies the number of filters that the driver and hardware implement on the overlay plane. Note that the operating system ignores this member.

pFilters

An optional pointer to a buffer that specifies the filters that the driver and hardware implement on the overlay plane. Note that the operating system ignores this member.

VideoFrameFormat

Specifies the overlay plane's video frame format, given as a value from the DXGI_DDI_MULTIPLANE_OVERLAY_VIDEO_FRAME_FORMAT enumeration.

Note This value must always be DXGI_DDI_MULIIPLANE_OVERLAY_VIDEO_FRAME_FORMAT_PROGRESSIVE. The operating system does not support the other enumeration values.

YCbCrFlags

Specifies YUV range and conversion info as one of the applicable values in the DXGI_DDI_MULTIPLANE_OVERLAY_YCbCr_FLAGS enumeration.

StereoFormat

Specifies the overlay plane's video frame format, given as a value from the DXGI_DDI_MULTIPLANE_OVERLAY_STEREO_FORMAT enumeration.

Note This value must always be DXGI_DDI_MULTIPLANE_OVERLAY_STEREO_FORMAT_MONO. The operating system does not support the other enumeration values.

StereoLeftViewFrame0

Reserved for system use. Must always be FALSE.

StereoBaseViewFrame0

Reserved for system use. Must always be FALSE.

StereoFlipMode

Specifies the overlay plane's stereo flip mode, given as a value from the DXGI_DDI_MULTIPLANE_OVERLAY_STEREO_FLIP_MODE enumeration.

Note This value must always be DXGI_DDI_MULTIPLANE_OVERLAY_STEREO_FLIP_NONE. The operating system does not support the other enumeration values.

StretchQuality

Specifies the overlay plane's stretch quality, given as a value from the DXGI_DDI_MULTIPLANE_OVERLAY_STRETCH_QUALITY enumeration.
