ARGUMENTSM, iM
FUNCTIONinvertAffineTransform
RETURN TYPEvoid
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Inverts an affine transformation.

The function computes an inverse affine transformation represented by 2 \times 3 matrix M:

\begin{bmatrix} a_{11} & a_{12} & b_1  \\ a_{21} & a_{22} & b_2 \end{bmatrix}

The result is also a 2 \times 3 matrix of the same type as M.

invertAffineTransform(M: Mat, iM: Mat): void;
M

Original affine transformation.

iM

Output destination, filled by the native operation. Output reverse affine transformation.
