156717 - Need a clean way to get an image from an nsIDOMNode

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Embedding: APIs, defect)

Description

[Conrad Carlen (not reading bugmail)]

From a context menu click on an image, the embedding app is given an nsIDOMNode
which represents the image. Depending on what the embedding app wants to do from
its context menu handler with that image, it's hard to get the actual image data
from it.

We have this code:
http://lxr.mozilla.org/mozilla/source/content/base/src/nsContentAreaDragDrop.cpp#1078,
but it's using all sorts of things we don't want embeddors to see. In addition,
nsIImage isn't something we want to make public either.

What I'd like to have is a service from which I could get an image object from a
DOM node and this image object would support copying to the clipboard and then
be QI'able to a platform specific image type so that the embedding app could
access the actual pixels if need be.

Marking a bunch of bugs in the "Embedding: APIs" component INCOMPLETE in preparation to archive that component. If I have done this incorrectly, please reopen the bugs and move them to a more correct component as we don't have "embedding" APIs any more.
