public: __property byte get_TargetContrast();
public: __property void set_TargetContrast( 
   byte value
);

public:
property byte TargetContrast {
   byte get();
   void set (    byte value);
}

Remarks

The default value is 127.

Valid values are 1 to 255.

This value sets the target contrast for document images, where contrast is calculated by comparing the 50th and 1st percentile brightness across the image. Images that have a contrast below the target range will have a contrast correction method recommended.
