Subject [FlexJS][SVG] foreignObject
Date Sun, 24 Jul 2016 07:38:43 GMT
I’d like to be able to enable adding HTML elements to SVG in FlexJS.

There is a mechanism for doing so, namely foreignObject.[1]

There’s two ways we can do this:

1. We can explicitly create a foreignElement class and only allow SVG containers to accept
SVG GraphicShapes or ForeignElements.
2. We can implicitly wrap standard HTML elements in foreignElement when it’s added to an
SVG container.

The other piece of this question is how to create the API in a way that it’ll work with
canvas as well.

Canvas can not truly accept a DOM element, but it can accept an image with SVG as a data URL.[2]

I’m not sure how approach #1 will work for canvas. Maybe we can have a “DOMWrapper”
class which would be a foreignObject in SVG and an Image which implicitly wraps everything
in foreignObject and SVG for canvas.

I’m not sure how #2 will work with the rest of FlexJS.
