Hi all,
I've tested the latest version of \limitatefirstline and it still
doesn't work as expected. This is really a complex story (problem).
- the clip mechanism cuts off the lowest part of some special chars
(clipping graphics is easy, but I don't understand what happens here)
- text is sometimes cropped at word boundaries (example 110pt),
instead of beeing clipped
The example file is appended and I use the latest beta. There is no
timeline, so fixing is not that urgent.
And yes, I've cancelled my hollidays and will live for the wiki only
from now on :)
wiki, wiki, wiki,....
Greetings,
Peter
