[Rtk-users] question about rtkDraw*ImageFilter

[Mathieu Dupont]

Hello everyone,

I have a question/suggestion about the set of rtkDraw*ImageFilter. This 
filter are written as additive filters: for example, in 
rtkDrawEllipsoidImageFilter.txx, we can find

for(..)
  itOut.Set( ellipsoid.density + itIn.Get() )

instead of

for(..)
itOut.Set( ellipsoid.density )


I think it can be more flexible the second option, because we can always 
associate Draw*ImageFilter and itkAddImageFilter to get an additive filter.

Moreover, the  rtkDrawGeometricPhantomImageFilter class already uses 
itkAddImageFilter in order to have additive filters (which is redundant 
in current situation).

What do you think ?
