Gets the InkTransform member data.
Syntax
HRESULT GetTransform(
[out] float *eM11,
[out] float *eM12,
[out] float *eM21,
[out] float *eM22,
[out] float *eDx,
[out] float *eDy
);
Parameters
[out] eM11
The real number that specifies the element in the first row, first column.
[out] eM12
The real number that specifies the element in the first row, second column.
[out] eM21
The real number that specifies the element in the second row, first column.
[out] eM22
The real number that specifies the element in the second row, second column.
[out] eDx
The real number that specifies the element in the third row, first column.
[out] eDy
The real number that specifies the element in the third row, second column.

This method can return one of these values.
| Return code | Description |
|---|---|
|
Success. |
|
An exception occurred inside the method. |
|
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 3x3 matrix because all 3x3 matrices that represent affine transformations have the same third column (0, 0, 1).
