I just wanted to verify if vtkImageResize is not available in VTK.js. Are there any plans to add it?
vtkImageResize is indeed not available in vtk.js.
Are you looking at the interpolation/antialiasing functionality or just some resizing/reshaping of the data array. If it is the later, then it would be easy to contribute and implement it in JS.
I am needing the intopolation/antialiasing functionality. I might try to pre-process the image data with another tool before bringing it into vtk.js.
