Windows Driver Kit DDI reference (ne-d3d10umddi-d3dwddm2_6ddi_scanout_flags)

D3DWDDM2_6DDI_SCANOUT_FLAGS enumeration

Description

Used in the PFND3DWDDM2_6DDI_QUERY_SCANOUT_CAPS callback to indicate the transformation requirement in preparation for a flip operation.

Constants

`D3DWDDM2_6DDI_SCANOUT_FLAG_NONE`

A transformation requirement is not defined.

`D3DWDDM2_6DDI_SCANOUT_FLAG_TRANSFORMATION_REQUIRED`

A transformation is required. If transformation is required, the runtime will call PFND3DWDDM2_6DDI_PREPARE_SCANOUT_TRANSFORMATION.

`D3DWDDM2_6DDI_SCANOUT_FLAG_TRANSFORMATION_DESIRED`

A transformation should occur. If there has been no API request to disable the transformation, then the runtime will call PFND3DWDDM2_6DDI_PREPARE_SCANOUT_TRANSFORMATION.

`D3DWDDM2_6DDI_SCANOUT_FLAG_UNPREDICTABLE_TIMING`

Indicates to the runtime whether the resulting allocation follows a predictable scanout timing or not. This information will be used to adjust the front-buffer rendering safety margins.

Remarks

The driver may not set both the D3DWDDM2_6DDI_SCANOUT_FLAG_TRANSFORMATION_REQUIRED and D3DWDDM2_6DDI_SCANOUT_FLAG_TRANSFORMATION_DESIRED flag.
