Sorry, I should have been more specific: my bmp images are grey-level 
images (in fact 2D ultrasound images saved in bmp format). Therefore I 
think all three channels should be the same. I just want to write a 
vtkStructuredPoints with SCALARS and not COLOR_SCALARS as it is now, 
because my other routines can only read SCALARS.
Thanks.
