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.
