Lock Method
Lock(BitmapLockFlags)
Provides access to a rectangular area of the bitmap.
Declaration
public BitmapLock Lock(BitmapLockFlags flags)Parameters
| Type | Name | Description | ||||||
|---|---|---|---|---|---|---|---|---|
| BitmapLockFlags | flags | The access mode you wish to obtain for the lock. This is a bitwise combination of BitmapLockFlags for read, write, or read and write access.
? |
Returns
| Type | Description |
|---|---|
| BitmapLock | A reference that receives the locked memory location. |
Remarks
Locks are exclusive for writing but can be shared for reading. You cannot call CopyPixels while the Bitmap is locked for writing. Doing so will return an error, since locks are exclusive.
