Render the attached FO to RTF and FOP generates some warnings that fo:leader is not supported. I can imagine that there may not be a direct equivalent to fo:leader in RTF but fo:leader is used to ensure that empty fo:blocks are not dropped. It may be possible to use for this purpose instead but other commercial renderers drop the block even with so fo:leader is used to keep the FO portable between the implementations. Even if full support for fo:leader is not possible in RTF, it would be very helpful it FOP could at least ensure the lines are not collapsed if an empty leader is present.
Created attachment 21103 [details] test FO File to reproduce
Still not working, I would like to help fixing the problem. Some hints would be welcome
Maximilan, as Chris already noted, it is not possible to fully map fo:leader into RTF. Some approximation might be possible. The place to implement this is org.apache.fop.render.rtf.RTFHandler.leader(Leader). You can find various test cases for leader in test/layoutengine/standard-testcases/leader-*.xml (use with ../testcase2fo.xsl). How exactly fo:leader should be mapped to RTF, I haven't investigated. Thanks for volunteering!
Created attachment 22161 [details] leader patch - leader supports fixed percent values for leader-length - most other properties - use-content, leader-pattern-width not implemented
Patch applied with modifications: http://svn.apache.org/viewvc?rev=674314&view=rev Thanks, Maximilian!
