Hello, Please find the corrections for Win32 attached.
to implement TCanvasIMp::Iconify(), TCanvasImp::Show() and TVirtualX::GetPlanes
methods.
There is still 256 indices constrain though. It sounds there was solid change of the ROOT
color model. That was not propagate to Windows implementation yet. That one can not fix
quickly. One has to learn the new model first.
Cheers,
Valeri
