AI-generated Key Takeaways
-
AffineTransform uses a 3x3 matrix to transform source coordinates into destination coordinates.
-
The transformation involves scaling, shearing, and translation of coordinates.
-
The class provides methods to retrieve the individual scaling, shearing, and translation elements.
-
An AffineTransform object can be used to create a new AffineTransformBuilder.
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;
