D3DLOCKED_RECT

  • Article

This structure describes a locked rectangular region.

typedef struct _D3DLOCKED_RECT {
  INT Pitch;
  void* pBits;
} D3DLOCKED_RECT;

Members

  • Pitch
    Pitch of surface, in bytes.
  • pBits
    Pointer to the locked bits. If a RECT was provided to the 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 7.0. It now refers to 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.)

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: D3d8types.h.
