XG_MIPLEVEL_LAYOUT Structure

Describes a single mip level in the hardware layout of a texture. Each mip level comprises a number of contiguous slices in the case of an array or volume texture.

Syntax

struct XG_MIPLEVEL_LAYOUT {
    UINT64 SizeBytes;
    UINT64 OffsetBytes;
    UINT64 Slice2DSizeBytes;
    UINT32 PitchPixels;
    UINT32 PitchBytes;
    UINT32 AlignmentBytes;
    UINT32 PaddedWidthElements;
    UINT32 PaddedHeightElements;
    UINT32 PaddedDepthOrArraySize;
    UINT32 WidthElements;
    UINT32 HeightElements;
    UINT32 DepthOrArraySize;
    UINT32 SampleCount;
    XG_TILE_MODE TileMode;
};
