TiledMemory Property

Summary

Gets or sets a value indicating whether to use tiled memory when loading an image.

Syntax

Objective-C

C++/CLI

Java

Python

public bool TiledMemory { get; set; }

@property (nonatomic, assign) BOOL tiledMemory;

public boolean getTiledMemory() 
public void setTiledMemory(boolean value)

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

TiledMemory # get and set (CodecsLoadOptions)

Property Value

Value	Description
true	To enable loading the image as tiled, useful for very large images.
false	To disable loading the image as tiled. The default value is false.

Remarks

When the value of this property is true, the image is created where the data pointers are maintained in tiles, useful for very large images.
