| AffineTransform2D | | public class AffineTransform2D extends AffineTransform implements Matrix(Code) | | An affine matrix of fixed
×
size. Here, the term "affine"
means a matrix with the last row fixed to
[0,0,1] values. Such matrices are used for
affine transformations in a 2D space.
This class both extends the Java2D
AffineTransform class and implements
the
Matrix interface. It allows interoperbility for code that need to pass the same
matrix to both Java2D API and more generic API working with coordinates of
arbitrary dimension.
This class do not implements the
XMatrix interface because the inherited
invert() method (new in J2SE 1.6) declares a checked exception,
setZero() would be an unsupported
operation (because it is not possible to change the value at
(2,2) ),
transpose() would fails in most cases, and
isAffine() would be useless.
