# CanvasPrintDialog v1.5
# ----------------------------------------------------------------------
# Implements a print dialog for printing the contents of a canvas widget
# to a printer or a file. It is possible to specify page orientation, the
# number of pages to print the image on and if the output should be
# stretched to fit the page. The CanvasPrintDialog is derived from the
# Dialog class and is composed of a CanvasPrintBox with attributes set to
# manipulate the dialog buttons.
