Remarks

Method returns type of affine transformation.

Transform matrix is m00 m01 m02 m10 m11 m12

According analytic geometry new basis vectors are (m00, m01) and (m10, m11), translation vector is (m02, m12). Original basis vectors are (1, 0) and (0, 1). Type transformations classification:

• TYPE_IDENTITY - new basis equals original one and zero translation
• TYPE_TRANSLATION - translation vector isn't zero
• TYPE_UNIFORM_SCALE - vectors length of new basis equals
• TYPE_GENERAL_SCALE - vectors length of new basis doesn't equal
• TYPE_FLIP - new basis vector orientation differ from original one
• TYPE_QUADRANT_ROTATION - new basis is rotated by 90, 180, 270, or 360 degrees
• TYPE_GENERAL_ROTATION - new basis is rotated by arbitrary angle
• TYPE_GENERAL_TRANSFORM - transformation can't be inversed
