Syntax
public static class Cache

The Cache type exposes the following members.

Properties
  NameDescription
Public propertyStatic memberCode exampleAllocatedDiskBytesCount
Gets the allocated disk bytes count.
Public propertyStatic memberCode exampleAllocatedMemoryBytesCount
Gets the allocated in-memory bytes count.
Public propertyStatic memberCacheFolder
Gets or sets the cache folder.
Public propertyStatic memberCode exampleCacheType
Gets or sets the cache scheme used.
Public propertyStatic memberCode exampleExactReallocateOnly
Gets or sets a value indicating whether reallocation should be exact or not. If reallocation is non exact the performance should be higher.
Public propertyStatic memberCode exampleMaxDiskSpaceForCache
Gets or sets the maximum available disk space for cache. The value specified is megabytes count.
Public propertyStatic memberCode exampleMaxMemoryForCache
Gets or sets the maximum available memory for cache in memory. The value specified is megabytes count.
Methods
  NameDescription
Public methodStatic memberSetDefaults
Sets the Cache settings to defaults.
Examples
This example demonstrates the use of Aspose.Imaging.Cache
[C#]

// By default the cache folder is set to user's local temp directory.
// You can also specify another cache folder than default like the following:
// Cache.CacheFolder = @"D:\\MyTemp";

// Auto mode is flexible and efficient
Aspose.Imaging.Cache.CacheType = Aspose.Imaging.CacheType.Auto;

// Default value is 0, which means there is no upper limit
Aspose.Imaging.Cache.MaxDiskSpaceForCache = 1073741824; // 1 gigabyte
Aspose.Imaging.Cache.MaxMemoryForCache = 1073741824; // 1 gigabyte

// It is not recommended to change the following property as it may greatly affect the performance
Aspose.Imaging.Cache.ExactReallocateOnly = false;

// At any time you may check how many bytes currently allocated for memory or disk 
// cache by examining the following properties
long l1 = Aspose.Imaging.Cache.AllocatedDiskBytesCount;
long l2 = Aspose.Imaging.Cache.AllocatedMemoryBytesCount;

// Do some image processing as below
Aspose.Imaging.ImageOptions.GifOptions options = new Aspose.Imaging.ImageOptions.GifOptions();
options.Palette = new ColorPalette(new Aspose.Imaging.Color[] { Aspose.Imaging.Color.Red, Aspose.Imaging.Color.Blue, Aspose.Imaging.Color.Black, Aspose.Imaging.Color.White });
options.Source = new Aspose.Imaging.Sources.StreamSource(new System.IO.MemoryStream(), true);
using (Aspose.Imaging.RasterImage image = (Aspose.Imaging.RasterImage)Aspose.Imaging.Image.Create(options, 100, 100))
{
    Aspose.Imaging.Color[] pixels = new Aspose.Imaging.Color[10000];
    for (int i = 0; i < pixels.Length; i++)
    {
        pixels[i] = Aspose.Imaging.Color.White;
    }

    image.SavePixels(image.Bounds, pixels);

    // after executing the code above there will be allocated 40000 bytes in-memory.
    long diskBytes = Aspose.Imaging.Cache.AllocatedDiskBytesCount;
    long memoryBytes = Aspose.Imaging.Cache.AllocatedMemoryBytesCount;
}

// The allocation properties may be used to check whether all Aspose.Imaging objects were properly disposed.
// In case you've forgot to call dispose on some object the cache values will be different than 0.            
l1 = Aspose.Imaging.Cache.AllocatedDiskBytesCount;
l2 = Aspose.Imaging.Cache.AllocatedMemoryBytesCount;
