Poetry formatting in epubs
Is there any way to preserve indentation and other special spacing used in poetry when making an EPUB? I'm pretty sure that you can't, based on the eBook Creator Guide, but I thought I would ask to make sure.
Or could you save it as a .jpg and put it in the EPUB that way? I think I just answered my own question, but I wouldn't mind confirmation on it!
