The D3D12DDI_RENDER_PASS_ENDING_ACCESS_PRESERVE_LOCAL_PARAMETERS_0101 structure specifies parameters for preserving a local portion of a resource at the end of a render pass.
AdditionalWidthSpecifies the additional width, in pixels, to be preserved on either side of the preserved region. A value of 0 means no extra pixels are preserved beyond the specified region. See Remarks.
AdditionalHeightSpecifies the additional height, in pixels, to be preserved above and below the preserved region. A value of 0 means no extra pixels are preserved beyond the specified region. See Remarks.
This structure is used when the ending access Type for a resource within a render pass is one of the following values. For each of these types, the beginning of the previous pass must specify the matching D3D12DDI_RENDER_PASS_BEGINNING_ACCESS_TYPE_0053_PRESERVE_LOCAL_*XXX* value and the same AdditionalWidth/AdditionalHeight parameters.

AdditionalWidth and AdditionalHeight must be set to 0 for D3D12DDI_RENDER_PASS_ENDING_ACCESS_TYPE_0101_PRESERVE_LOCAL_RENDER because they don't make sense in the context of rendering.
If AdditionalWidth/AdditionalHeight parameters for the pass are nonzero, they define a border of additional pixel locations around the current one that can also be read. For instance, AdditionalWidth of 1 and AdditionalHeight of 2 means a region 3 pixels wide and 5 pixels tall around the current pixel can be read by the current pixel.
