zoom in/out on image_url object

Hi,

I’m trying to understand how to use bokeh to plot images

I’m using bokeh from git master in a jupyter notebook.

The code I’m using is:

from bokeh.plotting import figure, show

``
from bokeh.io import output_notebook

from bokeh.models.tools import BoxZoomTool

output_notebook()

#img size in pixel

x,y=[3392.0,701.0]

TOOLS = ‘pan,box_select,crosshair,resize,reset,hover,wheel_zoom’

p = figure(x_range=(0,3392), y_range=(701,0), tools=TOOLS)

p.add_tools(BoxZoomTool(match_aspect=True))

p.image_url(url=[‘bathy.png’], x=0.0, y=0.0, w=1.0, h=1.0)

show§

The reason why I’m using git master is because of the option:

match_aspect=True

``

But seems that the parameters w,h are being ignored and the zoom doesn’t respond as expected.

Thanks for any advice.

Massimo.
