How to automatically justify text?
Hello,
Is there any way to have Calibre justifying automatically all the text downloaded with the recipes? Thanks. Francesco |

When you call ebook-convert from the command line, you can use --change-justification justify : http://manual.calibre-ebook.com/cli/...#look-and-feel
I however also wonder what is the equivalent in the gui? |

I have that checked but the ebook is still left-aligned. When I convert from mobi to mobi, it gets fixed. When I download via command-line, it is justified. Is this a bug or am I missing something? My target is kindle paperwhite, if it changes anything.

Hm, makes sense. But that would mean --change-justification does not have an equivalent in th egui :-(.

Hm, weird. That is the switch I was trying. This is the recipe I am using that shows different results with --change-justification and gui (normally you need password for full articles, but it should be visible even without one, I hope.)

The command line option and the gui option do not mean the same thing, apparently: https://bugs.launchpad.net/calibre/+bug/1255541
I solved this by including extra_css = 'p {text-align:justify}' in my recipe, but it is a bit ugly as somehow who prefers other justification would have to hand-edito the recipe. It would also not work if the source did not have all text in p tags. |
