plot.write_image(&out_file_name, ImageFormat::PNG, 2048, 1024, 1.0);

It is used to create images for entropy analysis.

What is the configuration that led you to this error? I can't reproduce it.

Kaleido is also broken in our setup where we use cargo --offline and build environment doesn't have access to the Internet. We don't create images for entropy analysis so hidding this behind a feature would be great.
