D3DWDDM1_3DDI_TILE_COPY_FLAG enumeration

Description

Identifies how to copy a tile using the CopyTiles function.

Constants

`D3DWDDM1_3DDI_TILE_COPY_NO_OVERWRITE`

The GPU isn't currently referencing any of the portions of destination memory being written.

`D3DWDDM1_3DDI_TILE_COPY_LINEAR_BUFFER_TO_SWIZZLED_TILED_RESOURCE`

The CopyTiles operation involves copying a linear buffer to a swizzled tiled resource. This means to copy tile data from the specified buffer location, reading tiles sequentially, to the specified tile region (in x, y, z order if the region is a box), swizzling to optimal hardware memory layout as needed. In this CopyTiles call, you specify the source data with the hBuffer parameter and the destination with the hTiledResource parameter.

`D3DWDDM1_3DDI_TILE_COPY_SWIZZLED_TILED_RESOURCE_TO_LINEAR_BUFFER`

The CopyTiles operation involves copying a swizzled tiled resource to a linear buffer. This means to copy tile data from the tile region, reading tiles sequentially (in x, y, z order if the region is a box), to the specified buffer location, deswizzling to linear memory layout as needed. In this CopyTiles call, you specify the source data with the hTiledResource parameter and the destination with the hBuffer parameter.
