Just wondering about some KnuthSequences for spaces I noticed
during a debug-session:
<snip />
Negative stretch is not the same as a positive shrink (and vice-
versa): a negative stretch is used to cancel (or diminish) a
positive one provided by some other elements: for each possible
break point, however, the overall stretch / shrink should always be
>= 0.
The meaning of the mini-sequence above is:
- if there is a break at the penalty element, there is some stretch
for
the line ending there
- otherwise, the overall stretch is zero
This is with unjustified text to give each line the same amount of
stretch, so that the algorithm should build lines with similar
length (while in justified text a line with many spaces and few
letters could be stretched a lot).
HTH
It did. Thanks for the quick explanation.
Cheers
