What does `Encoder.Version` do?

问题

Encoder.Version is one of the EncoderParameters which can be specified for e.g., saving a bitmap.

However it is essentially undocumented as far as I can tell. The documentation that does exist:

https://docs.microsoft.com/en-us/dotnet/api/system.drawing.imaging.encoder.version

actually has the wrong text in the remarks section.

So, what does this parameter do?

Thanks
