CDRF and WICD profiles are Candidate Recommendations, Call for Implementations

Compound Document Formats: Call for Implementations

  The Compound Document Formats Working Group has released four
  Candidate Recommendations: "Compound Document by Reference Framework
  1.0," "WICD Core 1.0," "WICD Full 1.0," and "WICD Mobile 1.0."
  Implementor feedback is welcome through 1 December. A preliminary
  implementation report is available, and a test suite is under
  development. The Web Integration Compound Document (WICD, pronounced
  "wicked") is a device independent Compound Document profile based on
  XHTML, CSS and SVG. The drafts describe presentation, linking and
  navigation behavior when multiple documents are combined. Read more
  about Rich Web Clients.

Hi.

I was able to modify the current Safari 3.02 browser (actually it's  
Webkit rendering engine), for it to support "WICD Rightsizing".

Lars and I then created some dedicated WICD content, to show the  
difference in behavior. Finally, we did a screen capture of how the  
two browsers render that content. A video of this is now available  
online. Hope you like it.

Out of curiosily, what kind of changes were needed?

Sorry for the late response. It's a while back, since I looked into  
this. But basically, this is what I did.

The HTML parent object element needs to be made aware of the aspect  
ratio of the embedded SVG child, as expressed by it's viewbox. So I  
modified method setViewBox() in WebCore/rendering/
RenderSVGContainer.cpp, for it to call node->document()->frame()-
 >ownerRenderer()->setIntrinsicSize() - I do so only, if ownerRenderer
() exist - and I provide it with the values of viewBox.width() and  
viewBox.height(). Then I modified method calcReplacedHeightUsing() in  
WebCore/rendering/RenderBox.cpp, so that it makes use of it's newly  
gained knowledge about the child's aspect ratio. This way, SVG  
children are not anymore shown in a fix 300 x 150 px box.

SVG children can now, for example, be embedded with a width, that is  
relative to their destination box. And their final height will be  
calculated, based on the relative width and their intrinsic aspect  
ratio.

My bug report and my patch are attached below.
