DecompositionLevels Property

Summary

Gets or sets the number of resolution levels in the compressed file.

Syntax

Objective-C

C++/CLI

public int DecompositionLevels { get; set; }

@property (nonatomic, assign) NSInteger decompositionLevels;

public: 
property int DecompositionLevels { 
   int get(); 
   void set (    int value); 
}

Property Value

Value that indicates the number of resolution levels in the compressed file. The maximum number of levels depends on the size of the image. Passing values that are too large will cause the save operation to fail. Each resolution level is one-half the size of the previous resolution, starting with the full image resolution. The default value is 5.

   //In the whole application
