Class AffineTransform
Page Summary
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;
