Class Overview

This class is basically a java-space replacement for the native android.graphics.Matrix class.

Math taken from senocular.com.

This class represents an affine transformation with the following matrix: 
 [ a , b , 0 ]
 [ c , d , 0 ]
 [ tx, ty, 1 ]
where:
  • a is the x scale
  • b is the y skew
  • c is the x skew
  • d is the y scale
  • tx is the x translation
  • ty is the y translation
