IndirectionImageSource Class |
The IndirectionImageSource class is used to provide an ImageSource which
can be modified after its initial creation. The ThumbnailImageViewerSynchronizer uses this class to
handle changes to the original ImageSource.

SyntaxThe IndirectionImageSource type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | IndirectionImageSource | Creates a new instance of IndirectionImageSource specifying the initial RandomAccessImageSource to use. |
Properties| Name | Description | |
|---|---|---|
 | ActiveImages |
Gets the active images.
(Inherited from ImageSource.) |
 | Count | Returns the total number of images in the image source. (Inherited from RandomAccessImageSource.) |
| CulledImages |
Gets the culled images.
(Inherited from ImageSource.) |
| Current | Returns the index of the current image. (Inherited from ImageSource.) |
| ImmediateUnload | Determines if an image should be unloaded from memory immediately. (Inherited from ImageSource.) |
| Item | Acquires the image at location i within the image source and returns it. (Inherited from RandomAccessImageSource.) |
| MemoryInUse | Returns an estimate of the number of bytes of memory currently in use by images in this
ImageSource. (Inherited from ImageSource.) |
| MemoryLimit | This sets the limit for memory usage for this ImageSource. If memory usage goes beyond
this, images will be dropped from memory until memory usage is below the limit. (Inherited from ImageSource.) |
| RetainInMemory | Gets or sets a value indicating whether the images should remain in memory once read. |
| TotalImages | Returns the total number of available images in this ImageSource. (Inherited from ImageSource.) |
| TotalImagesKnown | Gets a value indicating whether or not the total number of images in this image source can be known. (Inherited from ImageSource.) |
Methods| Name | Description | |
|---|---|---|
| Acquire(Int32) | Obsolete. This method has been deprecated. Use ReAcquire(AtalaImage) instead. (Inherited from ImageSource.) |
| Acquire(AtalaImage) | Obsolete. This method has been deprecated. Use ReAcquire(AtalaImage) instead.
(Inherited from ImageSource.) |
| AcquireNext | Acquire the next available image from the ImageSource. (Inherited from ImageSource.) |
| Add(AtalaImage) | Adds an AtalaImage to the end of the image source. |
| Add(Stream, Int32) | Adds an image to the end of the image source from a stream. |
| Add(String, Int32) | Adds an image to the end of the image source from a filename. |
 | AllImagesAreReleased |
Determines if all the images have been released.
(Inherited from ImageSource.) |
| Clear | Removes all items from the image source. |
| ContainsImage |
Determines whether this ImageSource contains the specified image.
(Inherited from ImageSource.) |
| CullNode |
Culls the node from the ImageSource
(Inherited from ImageSource.) |

| LowLevelFlushOnReset |
Lows level implementation to determine if there should be a flush on reset.
(Overrides ImageSourceLowLevelFlushOnReset.) |
| LowLevelHasMoreImages |
Lows level implementation to determine if the ImageSource has more images.
(Overrides ImageSourceLowLevelHasMoreImages.) |
| LowLevelReplaceImage |
Lows level implementation to replace an image.
(Overrides ImageSourceLowLevelReplaceImage(ImageSourceNode, AtalaImage).) |
| LowLevelReset |
Lows level implementation of reset.
