Missing methods and dependencies

[jourdain]

• dependencies could be optional but why don't we use vtk for the encoding? Is PIL faster?
• With the nice helper how do we push a render from the Python side? Ideally that should be a method on the widget if possible.

Also the example is not working for me on mac

Hi @jourdain,

thanks for the ping / issue and sorry about the delayed answer!

From my tests, PIL was slightly faster for encoding than VTK for JPEG.
The reason I used PIL instead of VTK was to be able to switch between file formats with only one implementation when VTK would require multiple implementations for the same result.

I also wanted to check what results we could have with WEBP and AVIF formats which are not supported by VTK.

The best in terms of speed would be to have hardware encoding directly.

Regarding the method, the way to do that is to call the RcaRenderScheduler's schedule_render method.
Do you want me to add the method to the Adapter as well and delegate to the scheduler?

For the MacOS problem, I'll try to reproduce.

For information, I found the problem on MacOS. The problem comes from the meta["type"] which is broken and write "image/RcaEncoder.JPEG" instead of "image/jpeg"

It seems to be related to this issue : python/cpython#100458
