I'd like to ask some questions that came up when I was trying to understand the redesigned code.
1. Some traits have been implemented (eg font-size) and others have not. For example the traits is-reference-area and is-viewport-area: Will they be implemented eventually or is it the idea that these traits are hard-coded into the classes - like "PageViewport" is obviously an area with is-viewport-area = true. 2. Some traits like "top-position" are implemented as members of the Area classes, I think (e.g. length, startIndent, getIPD and so on). Is there a plan as to which traits will be accessible by their names in the spec and which will be implemented through perhaps completely different means in the Area classes. I'm rather confused with respect to this issue, so I fear my question is rather unclear. 3. Im my imagination - or what I think I have understood from the spec - the area tree (once it is finished) holds all information that is needed before rendering. A renderer then takes the area tree and has a more or less trivial task of actually painting what is described in the area tree. In particular a renderer that is capable of adressing the output medium in any order should be able just to translate fop coordinates to renderer-specific coordinates and paint 'it'. So here is my question: Why are currentIPPosition and currentBPPosition necessary in the AbstractRenderer? Why does the renderer have to increment these variables? In my opinion the positioning of areas to be rendered should be done by the layout task. The renderer just reads the position of eg word from the Word area (by accessing a trait or something else; see Q2). 4. This isn't a question actually: Whilst trying to understand the area tree and the rendering stuff I've written an XFig-renderer. The goal was to create an xfig-drawing that contains boxes for the different areas of a fo document (just on one page). The xfig renderer is working and is producing some boxes. As you can see by the questions above I don't know whether these boxes are 'right'. Is anyone interested in the xfig renderer? Thanks a lot for answering some or all of these questions.
