[vtkusers] Help : How To Change 8 Bits BMP Picture To 24 Bits ?

[JohnMark]

Hi , vtkusers ,
 
    with the help of classes vtkStructuredPoints and vtkBMPWriter , I change the DICOM pictures to BMP 
pictures successfully . however , I found the BMP pictures' format was wrong when I decided to use them 
to reconsturct ( i.e. , volume rendering ) . it asked for 8 bits' BMP pictures , not 24 bits . So , I 
want to know whether there is a class changing 24 bits BMP picture to 8 bits ? 
 
    and I find there is not a function to do so in vtkStructuredPoints . 
 
    thank you for any help ! 
 
    Mark
