How to generate a png/jpg image out of a design

[ansamassidd]

Hello Community,

I am using a Modeler object (generated by launch_modeler_with_spaceclaim) to create a design (with extruded sketches) and export as a stp file. So far so good.

I wonder if there is a programmatic way to generate an enjoyable png/jpg image out of a design.
Actually I am able to generate a png by simply calling the save method on a Design object. The problem is that the generated image, in many cases, doesn't render the solid effectively (possibly because the point of view is shifted or the zoom is excessive).

Any insight?

Hi @ansamassidd! The Design, Component and Body objects have the option to take a screenshot of your 3d body using PyVista's capabilities. For example:

design.plot(screenshot="result.png")

This will render a 3D view of your design and store it in a screenshot. The view will be always in Isometric mode, and that's probably something we can enhance...

Another option is to use the screenshot button directly in the plotter. If you run the following:

design.plot()

And then change your view/zoom as desired with your mouse, you can finally click on the "Screenshot" button to save it as a PNG file as well. In the image, I framed the screenshot button in a red box for visibility.

Hope all this helps!

Hi @RobPasMue,

thanks a lot for your reactive and exhaustive response.
Your first piece of advice well suites my use case, because I need the screenshot to be generated programmatically.

The file that gets saved on my filesystem is exactly what I was looking for.

However, I see that a pyvista window pops up for a short amount of time (<1s). Is it possible to avoid this side effect?

[RobPasMue]

Yes, that is possible. Add the following lines at the top of your script:

import pyvista as pv

pv.OFF_SCREEN = True

This will prevent PyVista from popping up =)

It works perfectly. Thank you Roberto!

Awesome, glad it helped!
