Hello Nicolai,

I’ve pushed your fixe into Rubric.
It works as expected.
thanks a lot!.


 Where ? What ?

I did not fix rubric. :)

My fix was for the BitBltDisplayScanner.

Or do you mean this example.

It is interesting, does it mean rubric was always able to render underline and strokeouts?

 
Cheers
Alain

Thanks for the feedback, Sean.
Meanwhile, I think I found the reason. I think it got lost during the merge of Display- and MultiDisplayScanner. I upload a fix, ready for review.


Athens TextMorph drawing does not support this yet. And I think there is now support for this in TxText.

Anyone knows how about Rubric? I saw some examples with texdecorations, but I don't see how they are used from
within an editor.

Off the top of my head, I remember having a problem when the font I
requested didn't exist. I would get a fallback font without any of the
emphases I requested. HTH.
