## Bitmap::LockBits(const Rectangle\&, Imaging::ImageLockMode, Imaging::PixelFormat) method


Locks a [Bitmap](../) into system memory.

```cpp
Imaging::BitmapDataPtr System::Drawing::Bitmap::LockBits(const Rectangle &rect, Imaging::ImageLockMode flags, Imaging::PixelFormat format)
```


| Parameter | Type | Description |
| --- | --- | --- |
| rect | const Rectangle\& | A rectangle that specifies the region of the image to lock |
| flags | Imaging::ImageLockMode | Specifies the access level to the bitmap |
| format | Imaging::PixelFormat | The data format of this bitmap |

### ReturnValue

A shared pointer to a BitmapData object that contains information about the performed lock operation
