487822 - Allow currentScale and currentTranslate.x/y to work on non-root <svg>

Status: RESOLVED DUPLICATE of bug 365901

(Core :: SVG, defect)

Description

[Hardeep]

User-Agent:       Opera/9.64 (X11; Linux i686; U; en) Presto/2.1.1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1b3pre) Gecko/20090316 Shiretoko/3.1b3pre

The current implementation for svg zoom only allows for zooming on svg documents as a whole however I would like to implement zooming on all svg capable douments such as a xhtml document. This would allow for users to zoom svg images that are inline in a document and not just svg documents. The zooming feature would be similar to a flash video zoom as well as panning.

Reproducible: Always

There are extensions that do this too.

I've changed the summary to more accurately reflect what I think this bug is about: allowing currentScale and currentTranslate.x/y to work on non-root <svg>. I had a long conversation with Hardeep on IRC about this a day or two ago. The consensus in previous SVG WG conversations was also that we should do this, and it's something that Opera has done for a while (I believe Safari too?). Anyway, to be clear, this bug is not about the user interface aspects of zooming and panning of sub-document fragments, but just the underlying SVG changes to support it cleanly with SVGZoom/SVGScroll events correctly being dispatched to the zoomed/panned SVG fragment. Hardeep can file a bug in the Firefox component for UI changes once this is working and he has proposed UI, but that's a separate issue.

Sounds like this is bug 365901 then.

Ah, so it is. Hardeep, I'll assign that bug to you, okay?

This really needs bug 474230 to land first. Can you complete your review of that Jonathan?
