[Paraview] exporting selection labels to an SVG as editable/movable text-objects

[Dr. Roman Grothausmann]

Dear Dave,


Many thanks for Your reply and for opening a bug report. I wonder if it would be 
possible to extend the glyph filter to allow rendering text labels as "glyphs" 
because the Selection Inspector labelling cannot be save in a state file. If I 
do so and want to reload it I get the message:

ERROR: In 
/home/utkarsh/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release/paraview/src/paraview/VTK/IO/XMLParser/vtkXMLParser.cxx, 
line 483
vtkPVXMLParser (0x40172f0): Error parsing XML in stream at line 4409, column 38, 
byte index 217112: not well-formed (invalid token)

Root does not exist. Either state file could not be opened or it does not 
contain valid xml
Case not handled.


I guess though that the problem with the export to vector-graphics would remain 
the same.

Many thanks for Your help
Roman
