http://issues.apache.org/bugzilla/show_bug.cgi?id=41652 ------- Additional Comments From [EMAIL PROTECTED] 2007-02-18 13:18 ------- Further investigation and debugging confirm my suspicion, I think: In both cases, with or without the intermediate space, the list returned by the TextLM consists of 4 InlineKnuthSequences. Without the intermediate space, the second sequence contains only a KnuthPenalty corresponding to the preserved linefeed. My initial idea of Inserting a space character would lead to undesirable outcomes, in for instance the following case: <fo:block linefeed-treatment="preserve">xxxx <fo:inline background-color="blue"> yyyy</fo:inline> zzzz</fo:block> in case there is a space on the 'empty' line, one would expect the blue background to appear for the width of one space character. In case it's just two consecutive linefeeds, the line should be completely empty, so no background should be visible... I see a possible fix in adding the following to fop.layoutmgr.InlineKnuthSequence.endSequence(): if (!isClosed) { if (isEmpty()) { add(new KnuthGlue(1, 0, 0, null, true)); } ... Or in English: if endSequence() is called on an empty sequence, add a dummy glue element. The glue will be suppressed because of the following infinite penalty, so will leave no trace behind when background colors are used, like in the above example, but it will trigger the generation of the expected empty line (in AreaTree terms: an empty linearea, or one containing only an empty inlineparent of zero ipd) I'm going to leave it open FTM, to allow others to comment in on the proposed change. -- 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.
