karlcow: media attribute isn't deprecated HTML. So makes no sense to remove it from SVG.
06:54:06 [krit]
karlcow: should we keep it and close the ticket
06:54:34 [krit]
Vinay: It should be fine. Lets close the bug
06:55:03 [krit]
RESOLUTION: Keep media attribute in the spec and close bug as HTML still has the attribute as well

topic: Should getBBox returns values when the shape can't be drawn
06:55:35 [krit]
https://github.com/w3c/svgwg/issues/1018

06:55:37 [nzimmermann]
sorry for being late, we had a power cut :-(
06:56:59 [krit]
karlcow: If with or height are negative, we should make everything 0 in getBBox
06:57:09 [krit]
karlcow: ...according to last resolution
06:58:32 [krit]
dmangal: We should not throw if there are invalid values.
06:58:59 [krit]
dmangal: I am concerned what we should return: everything 0 or only the width/height dimension turn 0
06:59:30 [krit]
dmangal: an element with 0 dimension does have a bounding box according to spec
06:59:51 [krit]
dmangal: according to the paragraph in qiuestion. Should we change the paragraph?
07:00:13 [krit]
karlcow_: The resolution shouldn't have any affect on the rest of the SVG document IMO
07:00:30 [krit]
karlcow_: Putting everyhthing to 0 seems to be simplest
07:00:45 [krit]
nzimmermann: Most obvious would be 0 everything.
07:01:07 [krit]
nzimmermann: Elements with 0-dimension doesn't have an effect on parent bounding box.
07:01:25 [krit]
nzimmermann: So there is no value to keep position and make dimension only 0
07:01:51 [krit]
nzimmermann: seems to be natural to return 0
07:02:29 [krit]
dmangal: A path can be 1 dimensional. Would that be different?
07:03:06 [krit]
krit: M 100 100 L 100 100 as example
07:03:15 [krit]
nzimmermann: valid question
07:03:28 [krit]
nzimmermann: we should test this scenario
07:03:55 [krit]
karlcow_: We should create WPT tests first and see what browsers return and decide based on the results.
07:05:31 [krit]
nzimmermann: there is no way to fill a dot. But of course we can stroke it. SVG2 does have arguments for getBBox. So maybe one can differentiate between getBBox w/o arguments and an argument for getting the stroke boundingbox
07:06:11 [krit]
nzimmermann: We should test these scenarios. Agree with karlcow_ : we should base our decision on the results on WPT.
07:06:22 [krit]
karlcow_: Who'll create the tests
07:06:27 [krit]
dmangal: I will
07:06:58 [krit]
ACTION: dmangal will create more detailed getBBox tests for WPT and also take the arguments into account.
07:07:52 [krit]
karlcow_: The paragraph you found almost looks like an algorithm. There are many places in SVG2 where things are said but not written as algorithm
07:07:58 [krit]
karlcow_: it is strange to me.
07:08:10 [krit]
dmangal: It seems off from the rest of the paragraph
07:08:46 [krit]
topic: TPAC breakout session
07:09:11 [krit]
karlcow_: If there is anything you'd like to discuss at TPAC let me know. The breakout session is at the end of the day.
07:09:46 [krit]
ACTION: Add breakout session questions and send them to Karl
