'Declaration

Public Property InitAlpha As Boolean

'Usage

Dim instance As CodecsLoadOptions
Dim value As Boolean
 
instance.InitAlpha = value
 
value = instance.InitAlpha

public bool InitAlpha {get; set;}

@property (nonatomic, assign) BOOL initAlpha

public boolean getInitAlpha()
public void setInitAlpha(boolean value)

 <br/>get_InitAlpha();<br/>set_InitAlpha(value);<br/>Object.defineProperty('InitAlpha');

public:
property bool InitAlpha {
   bool get();
   void set (    bool value);
}

Property Value

true to set the alpha channel to ones (0xFF for 8-bit and OxFFFF for 16-bit), false to set the alpha channel to zeros.

Remarks

The default value for this property is true.

When loading 32-bit or 64-bit images that are known to have valid alpha channel information, you should set this property to false if you wish to retain the alpha channel in the loaded image.

The following formats will ignore this option, and will always retain alpha channel information during load:
