YOu are tryin gtoo hard! the point of FloatCanvas is for it do do this
stuff for you.
Try:
self.canvas.ZoomToBB()
That will zoom and pan so that everything on the canvas is shown.
If you want more control, you can pass in the bounding box you want to zoom
to and/or adjust the margins (extra space around the bounding box)
def ZoomToBB(self, NewBB=None, DrawFlag=True, margin_adjust=0.95):
"""
Zooms the image to the bounding box given, or to the bounding
box of all the objects on the canvas, if none is given.
:param NewBB=None: the bounding box you want to zoom in to.
If None, it will be calcuated from all the
objects on the Canvas.
:type NewBB: floatcanvas.utilities.BBox.BBox object (or something
compatible).
:param DrawFlag=True: If True, will force a re-draw, regardless of
whether
anythign has changed on the Canvas
:param margin_adjust=0.95: amount to adjust the scale so the BB
will have a
bit of margin in the Canvas. 1.0 shoud
be a tight fit.
:type margin_adjust: float
"""
Do poke into the code to see what's there -- one of these days I'll fire up
Sphinx an make a proper doc...
