Public Attributes
vx_size	numLevels
	Number of levels in the pyramid.

vx_image *	levels
	Array of images.

vx_float32	scale
	Scaling factor between levels of the pyramid.

vx_uint32	width
	Level 0 width.

vx_uint32	height
	Level 0 height.

vx_df_image	format
	Format for all levels.

struct _vx_platform *	platform
	Platform for ICD compatibility.

vx_uint32	magic
	Used to validate references, must be set to VX_MAGIC.

vx_enum	type
	Set to an enum value in vx_type_e.

vx_context	context
	Pointer to the top level context. If this reference is the context, this will be NULL.

vx_reference	scope
	The pointer to the object's scope parent. When virtual objects are scoped within a graph, this will point to that parent graph. This is left generic to allow future scoping variations. By default scope should be the same as context.

vx_uint32	external_count
	The count of the number of users with this reference. When greater than 0, this can not be freed. When zero, the value can be considered inaccessible.

vx_uint32	internal_count

vx_uint32	read_count
	The number of times the object has been read (in some portion)

	The number of times the object has been written to (in some portion)

vx_sem_t	lock
	The reference lock which is used to protect access to "in-fly" data.

void *	reserved
	A reserved field which can be used to store anonymous data.

vx_uint32	index
	A field which can be used to store a temporary, per-graph index.

vx_bool	extracted
	This indicates if the object was extracted from another object.

vx_bool	is_virtual
	This indicates if the object is virtual or not.

vx_delay	delay

vx_int32	delay_slot_index

vx_bool	is_accessible
	This indicates that if the object is virtual whether it is accessible at the moment or not.

vx_char	name [VX_MAX_REFERENCE_NAME]
	The reference name.
