Flags Property (CombineCommand)

Summary

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 planes for the destination, source and resulting images.

Syntax

Java

Objective-C

WinRT C#

C++

public Leadtools.Imageprocessing.Effects.CombineCommandFlags Flags {get; set;}

Public Property Flags As Leadtools.Imageprocessing.Effects.CombineCommandFlags

public Leadtools.Imageprocessing.Effects.CombineCommandFlags Flags {get; set;}

@property (nonatomic, assign) LTCombineCommandFlags flags

public int getFlags() 
public void setFlags(int value)

get_Flags(); 
set_Flags(value); 
Object.defineProperty('Flags');

public: 
property Leadtools.Imageprocessing.Effects.CombineCommandFlags Flags { 
   Leadtools.Imageprocessing.Effects.CombineCommandFlags get(); 
   void set (    Leadtools.Imageprocessing.Effects.CombineCommandFlags ); 
}

Property Value

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

Remarks

If the user did not set any of the following flags:

Then the CombineCommand will internally use the SourceMaster, which means that all channels (red, green and blue) will be used from the source image. If the user did not set any of the following flags:

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