... (list) property name => value pairs |
Factory constructor for Gnome2::Canvas::Item subclasses.

$affine (arrayref) affine transformation matrix |
Replaces $item’s transformation matrix.

$affine (arrayref) affine transformation matrix |
Combines $affine with $item’s current transformation.
(x1, y1, x2,
