Maybe: readonly attribute unsigned long originalFullWidth; readonly attribute unsigned long originalFullHeight; readonly attribute double originalSourceX; readonly attribute double originalSourceY; readonly attribute double originalSourceWidth; readonly attribute double originalSourceHeight; 105596 1 ian 2014-05-09 21:43:04 +0000 Another option, rather than exposing the originalSource* members, is to expose the actual dictionary that was used to configure the object, as passed to the constructor. As in: readonly attribute ImageBitmapSettings settings; ...or some such. (Not sure if dictionaries can be exposed in this way.) 106187 2 junov 2014-05-16 17:20:39 +0000 Do we really need this? Isn't it trivial to set-up a promise resolve handler that adds these attributes to the ImageBitmap? 106193 3 ian 2014-05-16 19:30:10 +0000 For background, search for "4)" in: http://lists.w3.org/Archives/Public/public-whatwg-archive/2014May/0069.html This would obviously only be a convenience API, yes. 125540 4 annevk 2016-03-16 17:51:20 +0000 Resolving WONTFIX due to lack of implementer interest.
