Or, you can set the image resolution when the screenshot is saved: ('/path/to/image. Resolution of the view, which will then be inherited by the screenshot: render_view = () Image resolution can be set in one of two ways. To do so, you may use this code snippet: import os Parent directories will not be created automatically. The valid extensions are shown in parenthesesīefore saving the image, you must ensure that the directory it will be saved To specify the output file format, simply change the file extension in theįunction call path argument. Paraview supports saving images in a number of image formats, including: RenderView is the 3D window view type, but a view could be any The default view should be called 'RenderView1'. Or you can access the active view with: render_view = () Views can be found by name with: render_view = ('ViewName') Is the View object you would like to save. Relative to the directory from which the script was executed, and render_view Here, '/path/to/image.png' is the absolute path to the output file, or a path The basic Python API call for saving a screenshot looks like this: ('/path/to/image.png', render_view) The SaveScreenshot function is imported from the paraview.simple ![]() To save a ParaView screenshot in a Python script, first import the necessary When you’re ready, hit OK and your image will be saved. Save your image to, enter an image name in the “File name” field, and select a This may include image resolution, background color, or image quality.Īfter you’ve made your selection, hit OK.ģ) Finally, in the next window, navigate to the parent folder you’d like to With an open ParaView session, and a Render View you would like to save, do theġ) Select File > Save Screenshot from the top menu.Ģ) In the window that appears, make any screen capture adjustments that are ParaView session, both interactively from the GUI and from a Python script.įor the purposes of this article, we will be using Paraview 5.4.1.įor installation instructions, please see the guide forįor help running ParaView scripts, please see theīatch-execution instructions. Mpiexec -np 4 pvbatch -mesa DistributedSphere.This article is intended to serve as a guide for saving screenshots from a The ParaView Python API also supports parallel execution using MPI, in the following example 4 parallel processes are used: module load paraview To run this example, save the code on the cluster as DistributedSphere.py and call the script on one of the cluster login nodes with the following commands: module load paraview Rep.RescaleTransferFunctionToDataRange(True) The following example script uses the ParaView Python API to generate a sphere and save an image: from paraview.simple import * We reserve the right to kill long-running processes without prior warning if we find that they slow down the login nodes. You can either write such a python script yourself (see ParaView’s Python API documentation) or record the sequence from a ParaView session.Ĭaution: When running a script, keep in mind that you share the login nodes with everyone and do not run compute-intensive tasks for longer periods of time. ParaView offers a Python application programming interface (API) to automate more extensive data processing or reoccuring tasks. More information about foreground and background processes can be found in our Linux tutorial. This is not required, but it allows working with the same console while the ParaView window is open. Note also that in this example, ParaView is launched in the background by appending &. The option -mesa is required because Mesa support is necessary. Then the ParaView GUI can be launched with: module load paraview In order to use ParaView desktop on the OMNI cluster, connect to the cluster login nodes via SSH using X support, i.e. with the -X option. ParaView uses VTK, the Visualization Toolkit, to provide the visualization and data processing model. It is capable of rendering images and videos with user defined color and configuration settings. VTK data model To use ParaView effectively, you need to understand the ParaView data model. ParaView provides a powerful graphical user interface (GUI) to explore and filter simulation data. ![]() The ParaView documentation can be found here. To use it, you need to load the module paraview: module load paraview ParaView version 5.9.0 is installed on the OMNI cluster. ![]() ParaView is an open-source, multi-platform data analysis and visualization application.Ĭaution: Although ParaView is available accross all nodes, the application works only on the login nodes.
