Re: [Paraview] Mismatched image size returned from ViewPort image render
Hi Jordan,
I wonder if that is the issue that is addressed in this topic:
http://review.source.kitware.com/#/t/5425/
If so, I think this fix may be merged soon, as it has already been
approved. If you built the ParaView release you're running yourself, you
could always try to check out the topic and see if it fixes the issue
you're seeing.
Cheers,
Scott

ParaView gurus,
I am working on a project that uses the JSON RPC protocols provided by
ParaViewWeb. I've noticed that the image quality for ViewPorts seems bad
regardless of what is specified in the call to viewport.image.render (docs
here: http://www.paraview.org/ParaView3/Doc/Nightly/www/js-
doc/index.html#!/api/protocols.ParaViewWebViewPortImageDelivery ).
After decoding the returned image from the Base64 encoding, the JPEG image
comes out as 636x420, while the quality is listed as 100 and the original
size is 1440x850.
The JSON object passed to viewport.image.render looks like
{args:[{
localtime:1425413914878,
view:-1,
size:[1440,850],
quality:100}]
}
While the returned object from that RPC call looks like
{
image: very long encoded image text here,
localTime: 0,
stale: false,
size: [1440,850],
format: jpeg;base64,
global_id: 315,
mtime: 3068929,
workTime: 1
}
I've used two separate Base64 decoders, and both result in a JPEG image
that is 636x420, not the reported 1440x850.
Any idea what could be the problem here? Is this a bug in ParaViewWeb? I'm
running the latest stable ParaView release (4.3.1) on RHEL.
Thanks,
Jordan

[Paraview] Density of streamlines using StreamTracerWithCustomSource
Hello all. I'm using StreamTracerWithCustomSource filter to generate streamlines shed from a specific surface. There are no problems to achieve my goals but I was not able to find a way to control the density of streamlines. Is it possible to control the number of streamlines that are shed when using StreamTracerWithCustomSource filter? Thank you so much for your help.

Re: [Paraview] Density of streamlines using StreamTracerWithCustomSource
I believe that the streamline density is based on the points from the custom source. If you add or remove points in the custom source you should get more or less streamlines, respectively.

Re: [Paraview] Superbuilds and clusters

[Paraview] Rotational Degrees of Freedom
In many applications particularly engineering ones, structural finite elements are used such as beams and shells. In the case of beams, in addition to degrees of freedom representing translations there exist rotational degrees of freedom. Is there a way to make paraview 'recognize' these rotational degrees of freedom so that it's able to produce a correct deformed shape visualization? Thank you for your help.

Re: [Paraview] [EXTERNAL] Re: Superbuilds and clusters
When I try to search the binaries (i.e., pvserver and associated libraries), as follows, I don't see mesa. When I do this search on a good, I made it myself build, I do see mesa. cd ../lib/paraview.4.3 ldd * | egrep -i mesa Next, when I try to run with MPI, on the nodes of the clusters, 8 processes, I get the following: Display is not accessible on the server side. Remote rendering will be disabled.. And, as expected, when I visualize wavelet, I see remote rendering is off. This is with a remote rendering threshold of 0. I also have Show Annotation on. OK, I don't know what you are talking about, so I assume I am not running an X server. Let me rebuild overnight with OSMesa. What is the difference?

[Paraview] Vector Glyph with FieldData
Dear All, I am new to the ParaView. The software is quite nice and I can use it without any problems in many cases. But I get a trouble in rendering 2D vector with my vtk file which contains “Field Data” that is: # vtk DataFile Version 2.0 mag.vtk, Created by Freefem++ ASCII DATASET UNSTRUCTURED_GRID POINTS 46764 float … FIELD FieldData 1 mag.field 2 94956 float 2.45639014e+00 -6.87174034e+00 1.62697911e+00 -8.08913136e+00 … This is actually 2D FEM magnetic field data (Hx, Hy) produced by FreeFem++. Loading the vtk file(mag.vtk) to ParaView and I can see “mag.field” in the ParaView’s menu and “Magnitude/X/Y” next to the menu. Then select “mag.vtk” in Pipeline Browser and click Glyph icon in the ParaView menu to see some weird Arrow in RenderView window. I expect something in “Vectors” in Active Attributes” in “Properties” panel but the menu is empty. I would be really obliged if you could tell me the missing things in my procedure to show vector field with Arrow Glyph.
