I'm still planning to write my Table-header with "Continued" extension sometime in the mythical future when I get my head above water. Does this fall into #1 or #3? Is it really realisitic that I'll be able to get this done in a few days? I'm pretty good with Java and I have access to a couple of near-gurus.
As a refresher, the idea is make some table-header functionality that adds the word "Continued" (or anything) on all instances of the table-header but the first. I'm willing to make it very extensible, unless quick and dirty is just much easier. (IE - even hardcoding the word "Continued" somewhere, although I realize that won't help the group as much.) thx a lot -Matt Keiron Liddle wrote: > > Hi, > > I think you confusing a few things. > > Starting from this page: > http://xml.apache.org/fop/extensions.html > (it could be a bit better and there will be some examples one day) > > The default extensions are svg and the bookmarks so you can just use these. > > To make your own extension you need to consider what you want to do first. > > 1. do you want to put a formatting object area in the output, eg. some > text, block etc. > 2. do you want a graphic in the output, ie. somthing that could be done > with svg > 3. do you want to do some document specific settings such as what the > bookmarks does > also what version are you using, this is about the latest release. > > If 1. then you need to do a similar sort of thing to all other fo objects. > If 2. then you setup a class that can get a DOM and turn it into SVG. > If 3. then it is a bit more difficult. > > It doesn't say to extend ExtensionObj, this is just an example. > > More below... > > On 2002.01.10 18:15 Software AG wrote: > > Hi, there. > > > > Trying to create a FOP Extension I'm getting totally confused with the > > docs. > > The HTML document says to just have a look at org.apache.fop.extensions.* > > and implement the ExtensionObj interface.
