Hello fop-team, i'd like to spend again some time with enhancing the RTF support. I have been inactive for over a year now (sorry, i was quite busy). Do you want me to send patches, because i was inactive for such a long time? Or can i access the svn repository? I have received the fop-dev-mailing list, but usually have only read the subject lines.
I'd like to accomplish following tasks: (1) FOP has already support for white-space-treatment, linefeed-treatment and white-space-collapse. But the results of these implementations are only availabe in RTFHandler.endBlock. So i had introduced delaying processing of the FOs until endBlock. Unfortunatelly this makes the code quite complex and buggy, so i want to remove this (of course the rtf module won't support above mentioned attributes any longer). (2) I want to test support for fo:table. This had worked quite good before i introduced the delaying. But now the table-columns get not processed. This will be fixed when (1) is finished. Sorry, i didn't notice this malfunction. (3) Add support for baseline-shift="sub" and baseline-shift="super". (4) After all that i have to think about how we can get white-space-treatment, linefeed-treatment and white-space-collapse to work. The difficulty is that RTFHandler handles text nodes in its implementation of FOEventHandler.characters. But at this time FOP's algorithms have not been run. Currently i see three possibilities (just ideas: any comment appreciated): a. Find a solution without delaying processing any FOs. (I don't know how this could work, in spite of implementing the complete algorithm by myself just for the RTFHandler. Maybe this is the worst solution.) b. Find a solution by delaying *every* FO. This would make the FOInputHandler interface useless, because i just had to wait for a particular event (e. g. endPageSequence) and then iterate the passed PageSequence object. Would be a great effort and would introduce the same problems as described in (1). c. Maybe i should not process the text nodes in FOEventHandler.characters but simply add a placeholder to my rtf. When i reach endBlock i have to iterate the passed Block object and search only for FOText objects. The contents of these FOText's have to replace the placeholders. Kind regards, Peter Herweg
