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