AlphaChannelActiveBits Property

Show in webframe







Gets or sets a value indicating the active bits for the alpha channel.
Syntax
public int AlphaChannelActiveBits {get; set;}
'Declaration
 
Public Property AlphaChannelActiveBits As Integer
'Usage
 
Dim instance As CodecsJpeg2000SaveOptions
Dim value As Integer
 
instance.AlphaChannelActiveBits = value
 
value = instance.AlphaChannelActiveBits
public int AlphaChannelActiveBits {get; set;}
@property (nonatomic, assign) unsigned int alphaChannelActiveBits;
public int getAlphaChannelActiveBits()
public void setAlphaChannelActiveBits(int value)

Object.defineProperty('AlphaChannelActiveBits');
public:
property int AlphaChannelActiveBits {
   int get();
   void set (    int value);
}

Property Value

The active bits for the alpha channel. Possible values are 1 and 8. If the value is 1 it means the 256 levels of the 8-bit alpha channels will be transformed into two levels of value 255 or 0, using simple threshold. The threshold value is 127, so all values gt; 127 will be set to 255 and all values lt;= 127 will be set to 0. If the value is 8, all 256 levels of the 8-bit alpha channels will be compressed. This is the default value. This option should be used on a 32-bit bitmap: otherwise, it has no effect.
Example
For an example, refer to CodecsJpeg2000Options.
