Flags Property (CombineCommand)

Gets or sets flags from seven groups that define treatment of the source, treatment of the destination, the operation to use when combining the data, treatment of the resulting image, and the color plan for the destination, source and resulting images.

Syntax

Visual Basic
C#
WinRT C#
WinRT JavaScript
C++

public CombineCommandFlags Flags {get; set;}

'Declaration
 
Public Property Flags As CombineCommandFlags

'Usage
 
Dim instance As CombineCommand
Dim value As CombineCommandFlags
 
instance.Flags = value
 
value = instance.Flags

public CombineCommandFlags Flags {get; set;}

 get_Flags();
 set_Flags(value);

public:
property CombineCommandFlags Flags {
   CombineCommandFlags get();
   void set (    CombineCommandFlags value);
}

Property Value

Value that represent the flags. The flags apply only to the defined rectangles (not necessarily the whole image). You can use a bitwise OR ( | ) to specify one flag from each group.

Remarks

If the user didn't set any one of these flags:

Then the CombineCommand will internally use the CombineCommandFlags.SourceMaster which means that all of channels (red, green and blue) will be used from the source image.

If the user didn't set any one of these flags:

Then the CombineCommand will internally use the CombineCommandFlags.DestinationMaster which means that all of channels (red, green and blue) will be used from the destination image.
