Error when loading plugin

[luccascorrea]

Hello there,

I am running into this error when trying to load the plugin:

TypeError: Cannot read property 'getImageData' of undefined
    at VolumeRenderingPlugin.setupViewport (main.js?986.5500000305474:59)

This error happened to me while developing locally but it also happens using the demo URL (https://vtk-plugin.ohif.org/?url=https://s3.eu-central-1.amazonaws.com/ohif-viewer/JSON/PTCTStudy.json) which I guess would make it easier to reproduce it. In the demo project, it happens when I click the "Volume rendering" tool.

I am new to OHIF and VTK so I am not sure what is going on. Could anyone give me a hand? Thank you.

It works for me (chrome on mac). Maybe your browser doesn't support vtkjs (try the examples https://kitware.github.io/vtk-js/examples/)

Same problem here vtk.js examples from the site all work

EDIT: vtktools are not linked on the window object
EDIT: This is with current Chrome browser

Do you have plan fix them?
Thank you!

@Iam0620, this plugin will likely be deprecated in the near future. Most of our VTK work is now taking place in react-vtkjs-viewport and OHIF/viewers/extensions/vtk

Thank you @dannyrb !

Hi @miguelranklin. This actually stopped happening to me with the latest versions of the viewer.
