RegistrationOptions Enumeration

Summary

Represents the type of transformation to be performed during registration.

Syntax

Objective-C

C++/CLI

Java

Python

public enum RegistrationOptions

typedef NS_OPTIONS(NSUInteger, LTRegistrationOptions)

public final class RegistrationOptions 
    extends java.lang.Enum<RegistrationOptions>

public enum class RegistrationOptions

class RegistrationOptions(Enum): 
   Unknown = 0 
   XY = 1 
   RSXY = 2 
   Affine6 = 3 
   Perspective = 4

Members

Value	Member	Description
0	Unknown	Unknown transformation type. The transformation algorithm will be selected automatically.
1	XY	( 0x00000001)Perform XY translation using one pair of corresponding points during registration.
2	RSXY	Perform rotational, scaling and XY transformations using two pairs of corresponding points during registration.
3	Affine6	Perform rotational, scaling, shearing, and XY transformations using three pairs of corresponding points during registration.
4	Perspective	Perform perspective transformation using four pairs of corresponding points during registration.
