Use of vtkXMLImageDataReader

[rjsgml5698]

thank you for your reply. I will try it!

Do you know what is causing this error?

Cannot read property 'getPointData' of undefined

Is it a matter of the order of the code? An error occurs intermittently.

@rjsgml5698

imageData = vtireader.getOutputData();
dataArray = imageData.getPointData().getScalars();
dataRange = dataArray.getRange();
