Hello
I have a question.
Does vti(vtkImageData) only support 1channel? only greyscale?
Thank you
Here’s an example of a color image:

No it is not limited to 1 channel. Like all vtkDataSets, you can add as many arrays as you like, where each can have any number of components, to a vtkImageData.
The caveat however is that many of the dedicated image processing filters are written to operate on the vtkDataSet::ActiveScalars array. Note that despite “Scalars” in the name, this array is quite often a three component RGB array.
