Matrix::TransformPoints(Point*,INT) method (gdiplusmatrix.h)
The Matrix::TransformPoints method multiplies each point in an array by this matrix. Each point is treated as a row matrix. The multiplication is performed with the row matrix on the left and this matrix on the right.
Syntax

[in, out] Point *pts,
[in] INT count
);
Parameters
[in, out] pts
Type: Point*
Pointer to an array of Point objects that, on input, contains the points to be transformed and, on output, receives the transformed points. Each point in the array is transformed (multiplied by this matrix) and updated with the result of the transformation.
[in] count
Type: INT
Optional. Integer that specifies the number of points to be transformed. The default value is 1.
Return value
Type: Status
