_DXGK_MULTIPLANE_OVERLAY_POST_COMPOSITION_FLAGS structure

Description

A structure containing the flags describing the transformations applied to an image.

Members

`VerticalFlip`

Indicates that the image should be flipped vertically.

`HorizontalFlip`

Indicates that the image should be flipped horizontally.

`Reserved`

This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting the remaining 30 bits (0xFFFFFFFC) of the 32-bit Value member to zeros.

`Value`

Remarks

Applying VerticalFlip and HorizontalFlip simultaneously results in 180 degree rotation.
