GetAlphaChannelAsHBitmap Method

Returns an integer pointer which is a bitmap handle to a plane which is similar to an 8 bit gray scaled image.

Syntax

'Declaration
 
Public Function GetAlphaChannelAsHBitmap() As IntPtr

'Usage
 
Dim instance As Processor
Dim value As IntPtr
 
value = instance.GetAlphaChannelAsHBitmap()

public IntPtr GetAlphaChannelAsHBitmap()

public: IntPtr GetAlphaChannelAsHBitmap();

public:
IntPtr GetAlphaChannelAsHBitmap();

Remarks

Returning the handle implicitly reduces the image down to 24 bit. The alpha layer may be modified and restored via the AlphaAdd(IntPtr) method.

The original image must be a 32 bit image where 8 bits are the alpha layer and 24 bits are rgb layer.
