I can only guess what exactly the use-case is here, so can you please check that this is not something that could be covered by XSL 1.1 flow-map functionality? We don't support that, yet, but I think it's important to check that we don't create proprietary extensions for something that is actually available in the standard. What's the value for overflow-to? The id of another block-container? What's the content of the other block-container? Is this normally used for absolutely positioned block-containers? Maybe you could post an example of a PDF that uses this feature? That would be helpful. > 2. fo:block-container "smallest-font-size" attribute was added.

What's the behaviour if descendants of the block-container override the font-size? We've discussed another extension some time ago that might cover the same functionality: http://wiki.apache.org/xmlgraphics-fop/WhitespaceManagement Can you take a look and see if this would also cover your requirement? I mean, this wouldn't allow proportional down-scaling of the content, but actually just present alternatives. This extension was proposed as a means to fill free space on a page with advertisements or other info for the customer. In your case, you'd simply generate the content, say, 3 times with different font sizes. I'm not saying your idea is bad. I'm just trying to find the minimal set of necessary extensions so that FOP doesn't get much more complicated than it is already. FO without any extensions is already a brain-wrecker. What I can't tell, yet, is how this alternative would impact your overflow-to feature. > My company is in the health-care industry so the overflow is extremely > important for patient instructions and warnings. > > Let me know if you think these enhancements are suitable for extensions, or > if some other means is appropriate. > > Thanks, > Andrew > > -- > View this message in context: > http://www.nabble.com/FOP-Enhancements-tf4816337.html#a13778915 > Sent from the FOP - Dev mailing list archive at Nabble.com.
