wxAffineMatrix2D::wxAffineMatrix2D | ( | ) |
Default constructor.
The matrix elements are initialize to the identity matrix.
|
virtual |
Concatenate this matrix with another one.
The parameter matrix is the multiplicand.
t | The multiplicand. |
Implements wxAffineMatrix2DBase.
|
virtual |
Get the component values of the matrix.
mat2D | The rotational components of the matrix (upper 2 x 2), must be non-NULL. |
tr | The translational components of the matrix, may be NULL. |
Implements wxAffineMatrix2DBase.
|
virtual |
Invert this matrix.
If the matrix is not invertible, i.e. if its determinant is 0, returns false and doesn't modify it.
Implements wxAffineMatrix2DBase.

Check that this matrix is identical with t.
t | The matrix compared with this. |
|
virtual |
Check if this is the identity matrix.
Implements wxAffineMatrix2DBase.
void wxAffineMatrix2D::Mirror | ( | int | direction = wxHORIZONTAL | ) |
Add mirroring to this matrix.
direction | The direction(s) used for mirroring. One of wxHORIZONTAL, wxVERTICAL or their combination wxBOTH. |
bool wxAffineMatrix2D::operator!= | ( | const wxAffineMatrix2DBase & | t | ) | const |
Check that this matrix differs from t.
