Hi Rick,<div><br></div><div>The pixel type in vtkImageData is described by</div><div>1) the ScalarType</div><div>2) the NumberOfScalarComponents</div><div><br></div><div>If the ScalarType is Short (16 bits) and the NumberOfScalarComponents</div>

Does vtkImageData support 12 or 16 bits per channel data RGBA?<br>
<br>
It seems like it defaults to 8 bits per channel.<br>
<br>
It's not templated like ITK image data, and I can't seem to find info on this.<br>
<br>
<br>
Thanks<br>
