[vtkusers] how to transform 32 bits RGBA image to 32 or 16 bits RGB image ?

[Sébastien MARAUX]

Hello,

 

How can I convert a 32 bits RGBA (4scalars) vtkImageData to 24 bits RGB
(3 scalars) vtkImageData ?

 

How do I delete the fourth component ?

 

I tried to just “SetNumberOfScalarComponents” to 0 but it lead to a
false image, with “3 columns” effect

(seems that alpha value is read instead of second GRB, and so on).
