Summary: Functionnality break in handling transparency of
vtkContextItem vtkContextActor vtkContext2D
Description:
Hi,
In PCL (www.pointclouds.org), we have several structures that inherit from
vtkContextItem that we add to the scene per user request (circle, rectangle,
image...) using a vtkContextActor through:
vtkSmartPointer<vtkContextActor> new_actor =
vtkSmartPointer<vtkContextActor>::New ();
new_actor->GetScene ()->AddItem (some_item);
They used to work perfectly with vtk-5.8 with a transparent actor and only the
shape opaque. Without changing any code in our side but just building against
vtk-5.10.1 the transparency is not there anymore, there is black shade and the
shape drawn upon it.
I am attaching screen shots of the visual result with both vtk-5.8 and vtk-5.10
so that you can notice the difference yourself. Results were obtained on a
ubuntu precise I have no clue on how this can be fixed from our side or yours
but I would appreciate your help to get back 5.8 results.
Cheers,
