Class AffineTransform

AffineTransform

A 3x3 matrix used to transform source coordinates (x1, y1) into destination coordinates (x2, y2) according to matrix multiplication:

 [ x2 ]   [ scaleX shearX translateX ] [ x1 ]
 [ y2 ] = [ shearY scaleY translateY ] [ y1 ]
 [ 1  ]   [   0      0        1      ] [ 1  ]
 

After transformation,

 x2 = scaleX * x1 + shearX * y1 + translateX
 y2 = scaleY * y1 + shearY * x1 + translateY
