Microsoft DirectX 9.0 |
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.)
