14.2 Subclasses of trafo

The trafo module provides a number of subclasses of the trafo class, each of which corresponds to one trafo method. They are listed in the following table:

=.7 trafo subclass =1.3function

=.7 mirror(angle) =1.3mirroring at line through with direction angle in degrees.

=.7 rotate(angle, x=None, y=None) =1.3 rotation by angle degrees around point $(\mathtt{x}, \mathtt{y})$ , or , if not given.

=.7 scale(sx, sy=None, x=None, y=None) =1.3 scaling with scaling factor sx in -direction, sy in -direction ( $\mathtt{sy}=\mathtt{sx}$ , if not given) with scaling center $(\mathtt{x}, \mathtt{y})$ , or , if not given.

=.7 translate(x, y) =1.3 translation by vector $(\mathtt{x}, \mathtt{y})$ .

=.7 slant(a, angle=0, x=None, y=None) =1.3XXX
