D3DLOCKED_RECT Structure


Describes a locked rectangular region.

Syntax

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 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 Microsoft?DirectX?7.0. 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.)
