IsGlobalMemory Property

Summary

Determines if the memory allocated for the image data is a global Windows handle.

Syntax

Objective-C

C++/CLI

Java

Python

public bool IsGlobalMemory { get; }

@property (nonatomic, assign, readonly) BOOL usesGlobalMemory

public boolean isGlobalMemory();

public: 
property bool IsGlobalMemory { 
   bool get(); 
}

IsGlobalMemory # get  (RasterImage)

Property Value

true if the memory allocated for the image data is a global Windows handle; false, otherwise.

Remarks

If the value of this property is set, you must use Access and Release when using low level methods that access the image data directly. For more information, refer to Access.
