NoDiskMemory Property

Summary

Gets or sets a value indicating whether to allow disk memory when loading an image.

Syntax

Objective-C

C++/CLI

Java

Python

public bool NoDiskMemory { get; set; }

@property (nonatomic, assign) BOOL noDiskMemory;

public boolean getNoDiskMemory() 
public void setNoDiskMemory(boolean value)

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

NoDiskMemory # get and set (CodecsLoadOptions)

Property Value

Value	Description
true	To prevent loading the image using disk memory.
false	To enable loading the image using disk memory. The default value is false.

Remarks

When using tiled memory, the image data is stored in disk and not in conventional memory. Setting the value of this property to true will prevent the image from being created in disk.

Example

using Leadtools; 
using Leadtools.Codecs; 
 
using Leadtools.ImageProcessing.Core; 
 
 
public void DiskMemoryExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   string fileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
   // first, load the image using the default 
   RasterImage image = codecs.Load(fileName); 
 
   // make sure the image uses conventional memory 
   if (image.IsConventionalMemory) 
      Debug.WriteLine("This image uses conventional memory"); 
   else 
      Debug.WriteLine("This should not happen!!"); 
 
   image.Dispose(); 
 
   // now, load the same image this time using disk memory 
   codecs.Options.Load.DiskMemory = true; 
   codecs.Options.Load.NoDiskMemory = false; 
   codecs.Options.Load.NoTiledMemory = false; 
   codecs.Options.Load.TiledMemory = false; 
   image = codecs.Load(fileName, 0, CodecsLoadByteOrder.BgrOrGray, 1, 1); 
   codecs.Options.Load.Reset(); 
 
   // make sure the image uses unmanaged memory 
   if (image.IsDiskMemory) 
      Debug.WriteLine("This image uses disk memory"); 
   else 
      Debug.WriteLine("This should not happen!!"); 
 
   // Clean up 
   image.Dispose(); 
   codecs.Dispose(); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
