_DXGI_DDI_PRESENT_MULTIPLANE_OVERLAY structure

Description

Specifies overlay planes to display.

Members

`LayerIndex`

The zero-based index of the overlay plane to display. The top plane (in the z-direction) has index zero. The planes' index values must be sequential from top to bottom.

`Enabled`

Indicates whether the overlay plane specified by LayerIndex is enabled for display.

`hResource`

A handle to the resource that is displayed by using the overlay plane.

`SubResourceIndex`

The zero-based index into the resource, which is specified by the handle in the hResource member. This index indicates the subresource, or surface, on which an overlay plane is to be displayed.

`PlaneAttributes`

A structure of type DXGI_DDI_MULTIPLANE_OVERLAY_ATTRIBUTES that specifies overlay plane attributes.
