As I've said I edited the protocols.py of paraview web:
@exportRpc("pv.pipeline.manager.scalarbar.visibility.update")
def updateScalarbarVisibility(self, options):
lutMgr = vtkSMTransferFunctionManager()
lutMap = {}
view = self.getView(-1)
if options:
for key, lut in options.iteritems():
visibility = lut['enabled']
if type(lut['name']) == unicode:
lut['name'] = str(lut['name'])
parts = key.split('_')
arrayName = parts[0]
numComps = int(parts[1])
lutProxy = self.getColorTransferFunction(arrayName)
barRep =
servermanager._getPyProxy(lutMgr.GetScalarBarRepresentation(lutProxy,
view.SMProxy))
if visibility == 1:
barRep.Visibility = 1
#EDIT#
barRep.TitleColor=[1.0,0.0,0.0]
barRep.LabelColor=[1.0,0.0,0.0]
barRep.Enabled = 1
barRep.Title = arrayName
if numComps > 1:
barRep.ComponentTitle = 'Magnitude'
else:
barRep.ComponentTitle = ''
vtkSMScalarBarWidgetRepresentationProxy.PlaceInView(barRep.SMProxy,
view.SMProxy)
else:
barRep.Visibility = 0
barRep.Enabled = 0
lutMap[key] = { 'lutId': lut['name'],
'name': arrayName,
'size': numComps,
'enabled': visibility }
return lutMap

Maybe we need to see more context (how you got your hands on barRep,
and what else you did)? I just used ParaView Qt client to visualize
the wavelet, and I changed these colors before exporting the state as
a python script. I think the following covers what you should need to
do:
from paraview.simple import *
...
rv1 = CreateView('RenderView')
...
lut = GetColorTransferFunction('RTData')
...
repr = Show(someSrc, rv1)
repr.LookupTable = lut
...
repr.SetScalarBarVisibility(rv1, True)
...
lutColorBar = GetScalarBar(lut, rv1)
lutColorBar.TitleColor = [...]
lutColorBar.LabelColor = [...]
Then finally maybe a Render() is required?
If you do all that and the color doesn't change, there may be a bug.
Even though the protocols we have now do not allow for changing the
title and label color (at least not to my knowledge), you can manage
this all in your application code.
Hope this helps,
Scott

Hi,
I try to set the color legend font color in protocols.py of
paraview web visualizer.
def updateScalarbarVisibility(self, options):
...
barRep.TitleColor=[0.0,0.0,0.0]
barRep.LabelColor=[0.0,0.0,0.0]
but it doesn't change the color. Where can I change it (default)?
I would also show it as default.
regards
Daniel
