This is because of the default values for linefeed-treatment and whitespace-treatment (both handled inside fo.flow.Block.handleWhiteSpace() during refinement). > 2) the sequence of elements created for a space inside centered text is glue - > penalty - glue - box - penalty - glue > 3) the method LineLayoutManager.endSequence() removes penalty and glue > elements at the end of the sequence, before adding the final elements; thus, > the LineLM removes only the two last elements in the sub-sequence representing > a space, leaving the other 4 elements and corrupting the resulting sequence > So, the bug could be either in 1 (there should not be a trailing space) No, I don't think so.

Only 3 IMO. > As white space handling is not a code section I know very well, I'm going to > fix the endSequence() method. :-) Not the reason I'd have chosen, but I think it's the right place to fix it. :-) I know white space handling pretty well by now and the linefeed that is converted to a space in this case seems to be correct. It seems like white- space-collapse is the thing that is not working properly. I've also found something else earlier about leading spaces when white-space cannot collapse. I haven't fixed that problem, yet, but it's another story anyway. At any rate, we need good test cases to check for all the combinations. But I don't know if the layout engine facility is good enough to check for all the details that come into play here. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
