Declaration
[C++]
HRESULT GetTransform(
[out] float *eM11,

[Microsoft® Visual Basic® 6.0]
Public Sub GetTransform( _
eM11 As Single, _
eM12 As Single, _
eM21 As Single, _
eM22 As Single, _
eDx As Single, _
eDy As Single _
)
Parameters
eM11
[out] Gets the real number that specifies the element in the first row, first column.
eM12
[out] Gets the real number that specifies the element in the first row, second column.
eM21
[out] Gets the real number that specifies the element in the second row, first column.
eM22
[out] Gets the real number that specifies the element in the second row, second column.
eDx
[out] Gets the real number that specifies the element in the third row, first column.
eDy
[out] Gets the real number that specifies the element in the third row, second column.
Return Value
| HRESULT value | Description |
|---|---|
| S_OK | Success. |
| E_INK_EXCEPTION | An exception occurred inside the method. |
| E_POINTER | A parameter contained an invalid pointer. |
Remarks
An InkTransform object represents a 33 matrix that, in turn, represents an affine transformation. The object stores only six of the nine numbers in a 3 × 3 matrix because all 3 × 3 matrices that represent affine transformations have the same third column (0, 0, 1).
