issue rendering 2D vtk image

See original GitHub issue

itkwidgets 0.32.0 on OSX catalina, issues displaying image used by the 2D display notebook example (both code blocks work when I tried a 3D image)

This code works

import itk
from itkwidgets import view

view(itk.imread('cthead1.png'))

This doesn’t (nothing displayed, no error issued)

import vtk
from itkwidgets import view

reader = vtk.vtkPNGReader()
reader.SetFileName('cthead1.png')
reader.Update()
view(reader.GetOutput())

https://github.com/InsightSoftwareConsortium/itkwidgets/pull/402 Fixed it. My 2nd commit checks for a zdim==1. In that case set up the dims, spacing & origin as 2d arrays.

Closing this since #402 should have addressed it.

@zubair-ahmed-ai please try using itkwidgets 0.32.1. itkwidgets does support color RGB images. If issues are observed, please open another issue.
