Hello all,
I have a little problem with wrapping. I want to fill whole lines with
underlined spaces and I use fixed cell heights in a table. When I set a
negative padding and setSplitCharacter(...), I can achieve that text
exceeding the table width is just discarded, character by character.
However, the wrapping with spaces seems to work different. I guess that all
spaces are collapsed into white space and then just eliminated. When you run
the following program you can see my problem. I need the spaces to stay
there, because I have to use their underline as a layout element (that's a
requirement I have to meet).
Is there no other way to accomplish this than to change the source code of
iText / subclass a class? If it is like that, where approximately would I
have to make the adaptations? ;-)
Best regards,
Joachim Kanbach
