D3DLOCKED_RECT

Describes a locked rectangular region.

typedef struct D3DLOCKED_RECT {
    INT Pitch;
    void * pBits;
} D3DLOCKED_RECT, *LPD3DLOCKED_RECT;

Members

Pitch

Pitch of surface, in bytes.

pBits

Pointer to the locked bits. If a RECT was provided to the IDirect3DSurface9::LockRect call, pBits will be appropriately offset from the start of the surface.

Remarks

The pitch for DXTn formats is different from what was returned in DirectX 7. It now refers to the number of bytes in a row of blocks. For example, if you have a width of 16, then you will have a pitch of 4 blocks (4*8 for DXT1, 4*16 for DXT2-5.)
