SVG Text -> GFX surface conversion API

[liyang]

In dojox.gfx.utils there is a toSvg() API that concerts a GFX surface (whether it is VML based, or SVG, or even canvas), to SVG by creative use of the SVG render code. It would be really cool if there was an inverse API take SVG Text and convert it back to a GFX surface. Preferably without using XSLT.

The benefit of this would be:

1.) Pulling in a document into dijit.Editor that has inline SVG and being able to bind GFX to the inline SVG and manipulate it.

2.) Being able to load an SVG scene from a file (via xhr), and construct a GFX object from it that can be manipulated.

Two things:

1. Why no XSLT?

2. We already have some (unfinished) provisions for a somewhat similar thing: xxx_attach.js (e.g., svg_attach.js, vml_attach.js, and so on). They idea was to be able to instantiate a native DOM, and attach gfx object to existing elements. Clearly it is not a portable thing, yet it allows to introspect existing DOM.

A notice for implementation, there's xsl asset that converts svg to gfx already, namely:

• dojox/gfx/resource/svg2gfx.xsl
• dojox/gfx/resource/svg2gfx-simple.xsl

Because you can't apply xslt in the browser consistently (to my knowledge).

Replying to jaredj:

Because you can't apply xslt in the browser consistently (to my knowledge).

For my work I needed XSLT and wrote simple shims to support. Everybody is doing it one way and IE does it in its own way. But other than that it works fine. The only potential problem can be mobile browsers --- I never tested them for XSLT, they may skip on implementing it.

In any case I can contribute shims.

Given that no one has shown interest in creating a patch in the past 5+ years, I'm closing this as patchwelcome.
