Windows Driver Kit DDI reference (nc-d3d10umddi-pfnd3dwddm2_6ddi_prepare_scanout_transformation)

PFND3DWDDM2_6DDI_PREPARE_SCANOUT_TRANSFORMATION callback function

Description

Invokes the driver to schedule work to perform the necessary transformations from the input resource, to the "shadow" allocation which will actually be scanned out. The runtime may request that the driver only update a sub-region, if only a small portion of the resource has changed since the last time this was invoked.

Parameters

`unnamedParam1`

hDevice [in]

A handle to the device.

`unnamedParam2`

hResource [in]

A handle to the resource that is associated with the allocations.

`Subresource`

The subresource index.

`VidPnSourceId`

A zero-based ID of the video present source in a path of a video present network topology.

`PlaneIdx`

The index of the plane.

`pSubRect`

Pointer to a D3D10_DDI_RECT.
