Lines Matching defs:Transform
3 The Transform class implements various transformation matrix operations,
6 Transform instances are effectively immutable: all methods that operate on the
8 interesting side effect that Transform instances are hashable, ie. they can be

72 Transform instances are immutable: all transforming methods, eg.
