Instance Method Details

#==(t) ⇒ Boolean

Check that this matrix is identical with t.

Parameters:

Returns:

  • (Boolean)

def ==(t) end

#concat(t) ⇒ void

This method returns an undefined value.

Concatenate this matrix with another one.

The parameter matrix is the multiplicand.

//           | t.m_11  t.m_12  0 |   | m_11  m_12   0 |
  // matrix' = | t.m_21  t.m_22  0 | x | m_21  m_22   0 |
  //           | t.m_tx  t.m_ty  1 |   | m_tx  m_ty   1 |

Parameters:

#get ⇒ Array(Wx::Matrix2D,Wx::Point2DDouble)

Get the component values of the matrix.

Returns:

def get; end

#invert ⇒ Boolean

Invert this matrix.

If the matrix is not invertible, i.e. if its determinant is 0, returns false and doesn’t modify it.

//           | m_11  m_12  0 |
  // Invert    | m_21  m_22  0 |
  //           | m_tx  m_ty  1 |

Returns:

  • (Boolean)

# File 'lib/wx/doc/gen/affine_matrix2d.rb', line 174

def invert; end

#is_identity ⇒ Boolean Also known as: identity?

Check if this is the identity matrix.

Returns:

  • (Boolean)
