pydeck how to use on_view_state_change with orthographic view

[cornhundred]

Can we use on_view_state_change to trigger events when using an orthographic view?

view = pdk.View(
    type="OrthographicView",
    controller=True, 
)

If so, would we still have access to the bounds like 'nw', 'se', etc?

I followed the instructions to inspect the payload using an HTML widget using this function

def filter_by_viewport(widget_instance, payload):
    text.value = str(payload)

and saw outputs like this

{'type': 'deck-view-state-change-event', 'data': {'width': 985, 'height': 500, 'orbitAxis': 'Z', 'rotationX': 0, 'rotationOrbit': 0, 'target': [363.30811230604013, 362.781105203365, 4.490630090003833e-12], 'zoom': 0.24283613435629614, 'minRotationX': -90, 'maxRotationX': 90, 'minZoom': None, 'maxZoom': None, 'transitionDuration': 1, 'transitionInterpolator': {'_propsToCompare': ['target', 'zoom'], '_propsToExtract': ['target', 'zoom'], '_requiredProps': ['target', 'zoom'], 'opts': ['target', 'zoom']}, 'transitionInterruption': 1, 'nw': [-292.6427802433585, 81.44229149247451], 'se': [292.6427802433591, -81.44229149247454]}}

So it looks like I have the 'nw' and 'se' bounds.

Although the 'nw' and 'se' bounds appear to be opposite to each other and only change when zooming and not panning. I'm using pydeck version 0.6.2

Thanks for reporting @cornhundred. I'll investigate.
