Is there a way to wrap lines in pixels instead of bytes?

Hi @sry948749099,

Yes, see https://mgeisler.github.io/textwrap/ for an example where Textwrap is used to wrap text based on pixels.

The important part is this implementation of Fragment. The Fragment trait is what Textwrap uses when wrapping: you should implement it for your own custom type and then you'll be able to use all the wrapping algorithms on this type.
