<p dir="ltr">Hi Bill,</p>
<p dir="ltr">thanks a lot for your suggestion, which confirmed that the subset of VTK libs that I identified was really the minimum possible subset considering the VTK classes I am using (maybe I can remove just vtkViewsCore - still need to check - but in any case it takes just a few KBs).</p>
<p dir="ltr">Is there really no other way to further reduce this footprint?</p>
<p dir="ltr">Thanks and best regards,</p>
