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 public double getScaleX()
