Provides methods for creating graphics buffers that can be used for double buffering.
Assembly: System.Drawing (in System.Drawing.dll)
Thetype exposes the following members.
|Allocate(Graphics, Rectangle)||Creates a graphics buffer of the specified size using the pixel format of the specified Graphics.|
|Allocate(IntPtr, Rectangle)||Creates a graphics buffer of the specified size using the pixel format of the specified Graphics.|
|Dispose||Releases all resources used by the .|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|Invalidate||Disposes of the current graphics buffer, if a buffer has been allocated and has not yet been disposed.|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The class allows you to implement custom double buffering for your graphics. Graphics that use double buffering can reduce or eliminate flicker that is caused by redrawing a display surface.
The simplest way to use double buffering is to set the OptimizedDoubleBuffer control style flag on a control using the SetStyle method. Setting the OptimizedDoubleBuffer control styles flag for a control redirects all painting for the control through a default graphics buffer, without requiring any additional code. This flag is set to true by default.
The class provides methods for creating and configuring a graphics buffer. The Allocate method creates a BufferedGraphics, which is a wrapper for a graphics buffer that also provides methods you can use to write to the buffer and render its contents to an output device.
You can retrieve the for the current application domain from the static BufferedGraphicsManager.Current property. For graphically intensive applications such as animation, you can create a dedicated using the constructor, but for most applications the BufferedGraphicsManager.Current property will be sufficient.
The following code example demonstrates how to acquire the for the current application domain. This code is part of a larger example provided for the BufferedGraphics class.
