AutoProcess Property

Summary

Gets or sets a value which determines whether to automatically adjust the overlay image and position when the main image changes.

Syntax

Objective-C

C++/CLI

Java

Python

public bool AutoProcess { get; set; }

@property (nonatomic, assign) BOOL autoProcess

public boolean getAutoProcess(); 
public void setAutoProcess( 
   boolean booleanValue 
);

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

AutoProcess # get and set (RasterOverlayAttributes)

Property Value

true to automatically adjust the overlay image and position when the image is changed; false, otherwise.

Remarks

When the value of this property is true, the overlay image and position will automatically adjust when the main image is resized (zoomed in), scrolled, rotated, flipped, reversed, sheared, trimmed.
