hom_mat2d_invertT_hom_mat2d_invertHomMat2dInvertHomMat2dInverthom_mat2d_invert (Operator)

Name

hom_mat2d_invertT_hom_mat2d_invertHomMat2dInvertHomMat2dInverthom_mat2d_invert — Invert a homogeneous 2D transformation matrix.

Signature

hom_mat2d_invert( : : HomMat2D : HomMat2DInvert)

Description

hom_mat2d_inverthom_mat2d_invertHomMat2dInvertHomMat2dInvertHomMat2dInverthom_mat2d_invert inverts the homogeneous 2D transformation matrix given by HomMat2DHomMat2DHomMat2DHomMat2DhomMat2Dhom_mat_2d. The resulting matrix is returned in HomMat2DInvertHomMat2DInvertHomMat2DInvertHomMat2DInverthomMat2DInverthom_mat_2dinvert.

Attention

Note that homogeneous matrices are stored row-by-row as a tuple; the last row is usually not stored because it is identical for all homogeneous matrices that describe an affine transformation. For example, the homogeneous matrix is stored as the tuple [ra, rb, tc, rd, re, tf]. However, it is also possible to process full 3×3 matrices, which represent a projective 2D transformation.

Execution Information

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

Parameters

HomMat2DHomMat2DHomMat2DHomMat2DhomMat2Dhom_mat_2d (input_control) hom_mat2d → (real)

Input transformation matrix.

HomMat2DInvertHomMat2DInvertHomMat2DInvertHomMat2DInverthomMat2DInverthom_mat_2dinvert (output_control) hom_mat2d → (real)

Output transformation matrix.

Result

hom_mat2d_inverthom_mat2d_invertHomMat2dInvertHomMat2dInvertHomMat2dInverthom_mat2d_invert returns TRUE if the parameters are valid and the input matrix is invertible. Otherwise, an exception is raised.
