Methods

	Name	Description
	AbortEvaluate	Abort current processing as soon as possible. (Inherited from SoImageVizEngine.)
	Copy	Creates and returns an exact copy of the engine. (Inherited from SoEngine.)
	CopyFieldValues(SoFieldContainer)	Calls CopyFieldValues(fc, false). (Inherited from SoFieldContainer.)
	CopyFieldValues(SoFieldContainer, Boolean)	Copies the contents of fc's fields into this object's fields. (Inherited from SoFieldContainer.)
	Dispose	Releases all resources used by SoDisposable. (Inherited from SoDisposable.)
	EnableNotify	Notification at this Field Container is enabled (if flag == true) or disabled (if flag == false). (Inherited from SoFieldContainer.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	FieldsAreEqual	Returns true if this object's fields are exactly equal to fc's fields. (Inherited from SoFieldContainer.)
	Get	Returns the values of the fields of this object in the Open Inventor ASCII file format in the given string. (Inherited from SoFieldContainer.)
	GetAllFields	Returns a list of fields, including the eventIn's and eventOut's. (Inherited from SoFieldContainer.)
	GetEventIn	Returns a the eventIn with the given name. (Inherited from SoFieldContainer.)
	GetEventOut	Returns the eventOut with the given name. (Inherited from SoFieldContainer.)
	GetField	Returns a the field of this object whose name is fieldName. (Inherited from SoFieldContainer.)
	GetFieldName	Returns the name of the given field in the fieldName argument. (Inherited from SoFieldContainer.)
	GetFields	Appends references to all of this object's fields to resultList, and returns the number of fields appended. (Inherited from SoFieldContainer.)
	GetHashCode	Overrides GetHashCode(). (Inherited from SoNetBase.)
	GetName	Returns the name of an instance. (Inherited from SoBase.)
	GetOutput	Returns a reference to the engine output with the given name. (Inherited from SoEngine.)
	GetOutputName	Returns (in outputName) the name of the engine output (output). (Inherited from SoEngine.)
	GetOutputs	Returns a list of outputs in this engine. (Inherited from SoEngine.)
	GetStringName	(Inherited from SoBase.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	HasDefaultValues	Returns true if all of the object's fields have their default values. (Inherited from SoFieldContainer.)
	IsEvaluating	Returns true if the engine evaluation is in progress. (Inherited from SoImageVizEngine.)
	IsNotifyEnabled	Notification is the process of telling interested objects that this object has changed. (Inherited from SoFieldContainer.)
	IsSynchronizable	Gets the ScaleViz synchronizable state of this object. (Inherited from SoBase.)
	Set	Sets one or more fields in this object to the values specified in the given string, which should be a string in the Open Inventor file format. (Inherited from SoFieldContainer.)
	SetName	(Inherited from SoBase.)
	SetSynchronizable	Sets this to be a ScaleViz synchronizable object. (Inherited from SoBase.)
	SetToDefaults	Sets all fields in this object to their default values. (Inherited from SoFieldContainer.)
	StartEvaluate	Evaluate engine and dependencies in another thread without blocking the current one. (Inherited from SoImageVizEngine.)
	ToString	Converts this SoBase structure to a human readable string. (Inherited from SoBase.)
	Touch	Marks an instance as modified, simulating a change to it. (Inherited from SoBase.)
	WaitEvaluate	Wait for the end of engine evaluation. (Inherited from SoImageVizEngine.)

Remarks

For an introduction, see section OIV.ImageViz.Engines.ImageAnalysis.

In the continuous, or theoretical, case, area is defined as:

In the discrete, or actual, case, area is approximated by the number of pixels in X:

Where :

The area measure can be weighted by a size factor which characterizes the area of a single pixel. In which case, the measure is physically homogeneous to the area.

On a binary image, this module returns the number of non zero pixels in the image. Computed area takes into account pixel size.
