ParaViewWeb, vtk filters python description

Hi everybody,

Well, I found that using vtk Filter (Threshold, Clip, etc.) is simple within ParaViewWeb, we have a list of filters so that we can use the filters <at> http://paraview.org/Wiki/ParaView/Users_Guide/List_of_filters

We can use "threshold = paraview.Threshold({Input:proxy,ThresholdRange:[300,600]})" to applicate a threshold between 300 and 600 for an image.

So, my question is : where can I find the python script .py which describes the way of using vtk Filters in ParaViewWeb?

If there isn't any file python script like that, how can we define a function that take in value as described above? How can we tell the ParaViewWeb to take in different type of variable?

I mean : def ImageThreshold(proxy,ThresholdRange......) or something like that?

Thank you very much for your reply.

Good day everybody :)

Re: ParaViewWeb, vtk filters python description

I'm not sure I understand what you mean by "Where is the python file
which describes the way of using vtk Filters in ParaViewWeb?"

The one that is imported by default is the pwsimple.py which is an
extension of the simple.py of regular ParaView.

But having said that, you can't easily mix VTK filter and ParaView
proxy together, unless you just want to do some data processing
without rendering.
But as I remember, you did a ParaView plugin for that, so normally,
once loaded you should be able to use it.

Did you try to load that plugin at startup with the extra argument of PWServer ?

Re: ParaViewWeb, vtk filters python description

Hi seb, thank you for your quick reply.

I found that I can use vtk Filter like Threshold, Clip, etc. in ParaViewWeb by enter the arguments like I cited in my email. Like threshold = paraview.Threshold({Input:proxy,ThresholdRange:[300,600]}).

So I think there are perhaps some files like pwsimple.py that describe how can ParaViewWeb can use a Plugin. I search for all the .py file in ParaView and I can't find something like that.

I did succeed in doing a ParaViewWeb plugin.

I used your advice to define something as following :

def SimpleImageThreshold(proxy)

servermanager.Activeconnection.Modules.filter.SimpleImageThreshold(proxy)

Now if I want my plugin to take ThresholdRange=[300,600] as input like the original Threshold of ParaView, is that possible?

If yes, how can we define this?

Thank you very much indeed

Re: ParaViewWeb, vtk filters python description

If you managed to load your plugin (the C++ ParaView one) at startup,
then you will be able to use your filter as any other filter in
ParaViewWeb without using any ParaViewWeb plugin. Otherwise, the
python file that you are missing is in fact an XML file that list the
properties for each filters and sources inside ParaView.

PARAVIEW_src/ParaViewCore/ServerImplementation/resources/filter.xml

The labels without space are used as filter name and properties for
creating and controlling those filters...

Otherwise inside your ParaViewWeb plugin, you can provide a dictionary
as argument and just loop through its entry and set them in python.

Re: ParaViewWeb, vtk filters python description

Thank you Seb,

You mean the ParaView plugin at startup? Indeed, I copied the dynamique library .so in /install/lib/paraview-3.14/plugins and the plugin is loaded automatically into ParaView. It is then usable immediately in Python Shell.

However, I doubt that I can use the plugin directly in ParaViewWeb without loading it.

For exemple, I have a MyImageThresholdSMPlugin.so, also the plugin's name is MyImageThreshold. I called it sucessfully in Python Shell directly with reader2=MyImageThreshold(reader,ThresholdRange=[300,600]); (the values are given for exemple).

In ParaViewWeb, can I use it directly by calling var reader2=paraview.MyImageThreshold({Input:reader, ThresholdRange:[300,600]}); ?

In your previous reply, I have to load a Plugin by LoadPlugin command from simple.py. And then define a function that call the servermanager.Activeconnection.Modules.filters.MyImageThreshold(proxy) I wonder if they are the same thing? That why I ask if we have to write a MyImageThreshold.py so that our plugin is usable in ParaViewWeb.

Re: ParaViewWeb, vtk filters python description

In fact,

I call directly MyImageThreshold with threshold=paraview.MyImageThreshold({Input:reader, ...}) and I receive Uncaught TypeError : Object #<ParaView> has no method 'MyImageThreshold'

when I use threshold = paravie.Threshold(....) (origin threshold of ParaView) then it works. That why I think that we have to use some kind of descriptor?

Thank you Seb,

However, I doubt that I can use the plugin directly in ParaViewWeb without loading it.

In ParaViewWeb, can I use it directly by calling var reader2=paraview.MyImageThreshold({Input:reader, ThresholdRange:[300,600]}); ?

Re: ParaViewWeb, vtk filters python description

Please read that:

http://www.paraview.org/Wiki/ParaViewWeb_Manta_setting

Then forget Manta and do your own "manta-init.py" file that will only
load your plugin... And that's it... (You can rename the file, just
make sure you keep the consistency.)

Re: ParaViewWeb, vtk filters python description

Thank Seb,

I'm sorry if I forget one step. But I have always Uncaught TypeError: Object #<Paraview> has no method 'ImageThresholdPFE'

I did as follow:

File ImageThreshold.py

import paraview

paraview.simple.LoadPlugin('/home/.../vtkImageThreshold/bin/libImageThresholdSMPlugin.so',False)

paraview.simple.LoadPlugin('/home/.../vtkImageThreshold/bin/libImageThresholdSMPlugin.so',True)

My JavaScript

$ p = paraview; var reader = p.OpenDataFile('/home/.../myfile.mhd');

$ p.loadPlugins();

$ threshold = p.ImageThresholdPFE({Input:reader, ThresholdRange:[1000,1150]});

$ threshold = p.ImageThreshold();

$ var threshold = p.ImageThresholdPFE({Input:reader, ThresholdRange:[1000,1150]});

All the 3 ways have the same error Uncaught TypeError: Object #<Paraview> has no method 'ImageThreshold'

In fact, I used your advice with

def ImageThreshold(proxy,a,b):

servermanager.ActiveConnection.Modules.filters.ImageThreshold(proxy,ThresholdRange=[a,b])

but each time I called

$ var threshold = p.ImageThreshold([reader],1000,1150);

ParaViewWeb planted and I have to use kill - 9 to escape. Do you have any clue?

Thank you very much Seb

Please read that:

http://www.paraview.org/Wiki/ParaViewWeb_Manta_setting

Then forget Manta and do your own "manta-init.py" file that will only
load your plugin... And that's it... (You can rename the file, just
make sure you keep the consistency.)

Re: ParaViewWeb, vtk filters python description

What I'm talking about is a "--batch-file" not a ParaViewWeb plugin.
But never mind, if you really want to use a ParaViewWeb plugin you are
stuck by the fact that your ParaView object in JavaScript will NEVER
have your custom filter definition available. Which is NORMAL, and
that's why you get those errors.

The only way you can overcome that issue is to work directly on the
sever side using ParaViewWeb plugins. Which is what you basically do
now...

But your JavaScript should look like that (based on what you did.)

p = paraview;
var reader = p.OpenDataFile('/home/.../myfile.mhd');
p.loadPlugins();
p.plugins.ImageThreshold.ImageThreshold(reader, 1000,1150);

/// Here is the explanation of how the call is made:
// => p.plugins.${python file name}.${method name in your python
file}( the arguments of your methods )

But once AGAIN, if you start PWServer with the --batch-file argument
and a script that LOAD the ParaView plugin, then you will be able to
do that:

p = paraview;
var reader = p.OpenDataFile('/home/.../myfile.mhd');
p.ImageThreshold({proxy: reader,ThresholdRange:[a,b]})

Here is an example on what that batch-file should look like:

## init.py
import paraview
paraview.simple.LoadPlugin('/home/.../vtkImageThreshold/bin/libImageThresholdSMPlugin.so',False)
paraview.simple.LoadPlugin('/home/.../vtkImageThreshold/bin/libImageThresholdSMPlugin.so',True)
