Gets or sets a value indicating the active bits for the alpha channel.
public int AlphaChannelActiveBits { get; set; }
Public Property AlphaChannelActiveBits As Integer
@property (nonatomic, assign) NSUInteger alphaChannelActiveBits
public int getAlphaChannelActiveBits()
public void setAlphaChannelActiveBits(int 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.
