What about GeometryUtils / convertPointFromNode()

[Jörg Birkhold]

Hi there,

After the removal of webkitConvertPointFromPageToNode() and webkitConvertPointFromNodeToPage(), it is almost impossible to convert a point from a css transformed(rotated) element to the window/document K.O. system and vice versa.

Firefox has already implemented the Geometry Utils like convertPointFromNode(). Are there any plans to implement that in Blink?

Thanks 

Joerg

I've had a few discussions about Geometry Utils, I think it's valuable for Blink to implement. It's on the list of things for the style team to do, but as yet no one has signed up to do the work.

I think it is useful APIs.

If no one is working on this, I'm interested in implementing this.

I've implemented geometry interfaces such as DOMMatrix, DOMRect, DOMQuad and so on.

Especially, DOMQuad interface is only used by getBoxQuads() in geometry utils[1].

If someone is already working on this, please let me know :)

Thank you.

Sounds great. I don't think you'll have any problems with an intent-to-implement for this.

Implementing convertPointFromNode() sounds reasonable to me, although the spec is not done:

http://dev.w3.org/csswg/cssom-view/#dom-geometryutils-convertpointfromnodepoint-from-options

In the previous Intent to Implement: Geometry Interfaces there were concerns about performance, but perhaps with a new intent for a specific API using DOMPoint we could come to some resolution on that issue.

I don't know what reason for not implementation? Mozilla monopoly?
