Default interface provides access to the properties for setting the run-time expected position of a pattern and the uncertainty of the expected position. Character positions in a pattern are specified with respect to the expected position of the pattern.

Syntax
The CogOCVPatternPosition type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
 | CogOCVPatternPosition | Constructs a new instance of this class. |
| CogOCVPatternPosition(IntPtr) | Constructs a new instance of this class using com pointer. |
| CogOCVPatternPosition(CogOCVPatternPosition) | Constructs a new instance of this class as a deep copy of the given instance. |
Methods
| Name | Description | |
|---|---|---|
 | Clone | Returns a deep copy of this class instance. Derived classes that implement Clone should override this method; other clients who wish to clone this instance should call ICloneable.Clone. See also CogSerializer.DeepCopyObject |
| CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) |
| Dispose | |
| Dispose(Boolean) | |
| Equals | (Inherited from Object.) |
| Finalize | (Overrides Object Finalize .) |
| GetAttributes |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetClassName |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetComponentName |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetConverter |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetDefaultEvent |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetDefaultProperty |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetEditor |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetEvents |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetEvents( Attribute ) |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| GetObjectData | |
| GetProperties |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetProperties( Attribute ) |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetPropertyOwner |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| MemberwiseClone(Boolean) | Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.) |
| ResumeAndRaiseChangedEvent | Re-enables raising of the Changed event after SuspendChangedEvent has been called. Also raises the Changed event if the ChangedEventSuspended count is reduced to zero and any changes were made while events were suspended. Must be called once for each call to SuspendChangedEvent. |
| SuspendChangedEvent | Temporarily suspends the raising of the Changed event. May be called more than once, and a corresponding call to ResumeAndRaiseChangedEvent must be made for each call to SuspendChangedEvent. |
| ToString | (Inherited from Object.) |
Fields
| Name | Description | |
|---|---|---|
  | SfExpectedPose | This bit will be set in the EventArgs of a Changed event every time the value returned by ExpectedPose may have changed. |
| SfRotationUncertainty | This bit will be set in the EventArgs of a Changed event every time the value returned by RotationUncertainty may have changed. |
| SfScalingUncertainty | This bit will be set in the EventArgs of a Changed event every time the value returned by ScalingUncertainty may have changed. |
| SfSelectedSpaceName | This bit will be set in the EventArgs of a Changed event every time the value returned by SelectedSpaceName may have changed. |
| SfTranslationUncertainty | This bit will be set in the EventArgs of a Changed event every time the value returned by TranslationUncertainty may have changed. |
Properties
| Name | Description | |
|---|---|---|
 | ChangedEventSuspended | If nonzero, indicates that the raising of the Changed event has been suspended. This value is incremented when SuspendChangedEvent is called and decremented when ResumeAndRaiseChangedEvent is called. |
| ExpectedPose | The run-time expected position of a pattern. Character positions in a pattern are specified with respect to the expected position of the pattern. |
| HasChanged | If true, the serializable state of this object has changed since the last time it was serialized. |
| RotationUncertainty | Rotation uncertainty specifies the +/- range (in radians) that the pattern may vary from its expected rotation. Uncertainty value must be greater than or equal to zero. |
| ScalingUncertainty | Scaling uncertainty specifies the +/- range that the pattern may vary from its expected scaling factor. Uncertainty value must be greater than or equal to zero. |
| SelectedSpaceName | Specifies which space of the input image's coordinate space tree is used to define the expected position of the pattern. |
| TranslationUncertainty | Translation uncertainty specifies the +/- range that the pattern may vary from its expected x,y position. Uncertainty value must be greater than or equal to zero. |
Events
| Name | Description | |
|---|---|---|
 | Changed | Occurs when one or more parts of the object's state may have changed. |
Remarks
Interface that lets you specify the expected run-time position of the overall pattern. The pattern position is the pose of the pattern origin in the specified space of the input image, where the pattern origin is implicitly defined by the translation, rotation, and scale of the individual CogOCVCharacterPositions in the pattern.
