Properties

	Name	Description
	ActiveImages	Gets the active images. (Inherited from ImageSource.)
	Count	Returns the total number of images in the image source.
	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.
	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.)
	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.)

	LowLevelReset	Lows level implementation of reset. (Inherited from ImageSource.)
	LowLevelSkipNextImage	Lows level implementation to skip next image. (Inherited from ImageSource.)
	LowLevelTotalImages	Lows level implementation that returns the total number of images. (Inherited from ImageSource.)
	LowLevelTotalImagesKnown	Returns if the total images is known. (Overrides ImageSourceLowLevelTotalImagesKnown.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	NotifyChangedImage(AtalaImage)	This method is used to inform an ImageSource that one of its current acquired images has changed. (Inherited from ImageSource.)
	NotifyChangedImage(AtalaImage, AtalaImage)	This method is used to inform an ImageSource that one of its current acquired images has changed. (Inherited from ImageSource.)
	OnChangedImage	Raises the [E:ChangedImage] event. (Inherited from ImageSource.)
	OnNodeIndexSet	This method is called from the RandomAccessImageSource indexer after it has set the ImageSourceNode.Index value.
	OnReleasing	Called when Release(AtalaImage) was performed on an ImageSourceNode. (Inherited from ImageSource.)
	ReAcquire(Int32)	Acquire a previous image by index. (Inherited from ImageSource.)
	ReAcquire(AtalaImage)	Acquire an AtalaImage that has been previously acquired. (Inherited from ImageSource.)
	Release	Release a previously acquired image. (Inherited from ImageSource.)
	ReleaseChangedImage(AtalaImage)	Release an image that has changed, notifying other clients that the image has changed. (Inherited from ImageSource.)
	ReleaseChangedImage(AtalaImage, AtalaImage)	Release an image that has changed, notifying other clients that the image has changed. (Inherited from ImageSource.)
