transforms issues

dirk: can svg parsing do parsing with both svg and css parsing rules, without or with units? could svg change here?
... would like to modify the svg parser to accept css syntax for transforms, so e.g translate(20px, 20px) would be supported

rik: that's a big change

dirk: you have to use units in css syntax anyway

rik: but for an svg parser not having a css parser?

dirk: that's why i'm proposing extended to allow the css syntax, but without requiring a full css parser
... if we change transform to be a presentation attribute it's still a property

<ChrisL> all properties are presentation attribues, and the reverse is also true

ed: the current presentation attributes are still parsed as defined in svg, but we've discussed allowing css syntax (and parsing) in svg attributes

<ChrisL> presentation attributes differences from style sheets: units, scienetific notation, case sensitivity

dirk: i also wanted to suggest aryeh gregor as an editor for the merged transforms spec

cl: is he member of css or svg wg?

dirk: he's a member of csswg

<ChrisL> https://www.w3.org/2000/09/dbwg/details?group=32061&public=1

<ChrisL> sorry, misread. yes, he is

<scribe> ACTION: dirk to contact all the editors of http://dev.w3.org/csswg/css3-transforms/ to see if they agree to have Aryeh Gregor as an editor too, and send a mail to public-fx about it [recorded in http://www.w3.org/2012/02/13-fx-minutes.html#action01]

<trackbot> Created ACTION-69 - Contact all the editors of http://dev.w3.org/csswg/css3-transforms/ to see if they agree to have Aryeh Gregor as an editor too, and send a mail to public-fx about it [on Dirk Schulze - due 2012-02-20].

<ChrisL> minutes are here (scroll down to Transforms )

<ChrisL> http://lists.w3.org/Archives/Public/www-style/2012Feb/0550.html

<ChrisL> quote "David: I don't want 2d to wait on SVG stuff.

<ChrisL> David: 2d is not going to change. "

CL: smfr claimed 2d transforms is css only, not fx
... pointed out that svg had had transforms much longer, but people didn't want to slow down

rik: the 2d spec, not the combined one?

cl: also concerns about where bugs were tracked
... csswg wants to push ahead with 2d transforms
... perhaps driven by the prefix discussions

CC: canon was interested in having 3d transforms in svg
... we were happy with it being a combined spec
... but don't want it to be css only
... it needs to work in svg

<ChrisL> I agree with Cyril

<ChrisL> and its sad there is no-one (except for myself) from CSS WG here

dirk: currently working on the merged transforms spec, we're mostly clear on transform-origin e.g
... there's no conclusion from the minutes CL pasted that says the csswg will continue with the 2d transforms independently

CL: the minutes are a bit partial, vincent argued that we should work together
... and there are issues with the spec still
... some issues joint between 2d and 3d
... we should discuss this in Hamburg

<ChrisL> I hope we can move forward on a joint spec at the Hamburg meeting, since we are colocated SVG and CSS at that f2f

CC: from the minutes, david says "I don't want to wait on 2d stuff", and svg has had transforms for 10-12 years, don't understand why css would have to wait for svg

<ChrisL> also unminutes was Simon querying if there were SVG tests for 2D transforms

CC: would be fine with transform with only 2d that is compatible with svg, and later one spec with 3d with support for svg as well

<ChrisL> quite a bit of what I said was unminuted, it seems

CL: would be good to have proposed resolutions for the Hamburg meeting

dirk: mayube the 3d stuff won't be ready, but 2d should be possible

<ChrisL> I agree, Simon is working hard on the 3d stuff

dirk: pretty sure we'll have a working draft to hamburg, 3d included

CC: simon says he was createing tests for 3d transforms

CL: some concerns from simon in the CSSWG meeting about testing transforms, but svg has had this tested for a long time
... should be possible to just take tests from svg

rik: seems many things went unminuted in the csswg meeting

dirk: can we resolve that svg will use css-like parsing rules?

CL: what would it say exactly?

ed: we can resolve things on the public-fx mailinglist, if enough people respond to the thread

<krit> http://pastebin.com/HWC7mq6y

dirk: only thing missing is that svg supports scientific notation for numbers

ed: ok, let's try and resolve this on the list

issue-66

http://dev.w3.org/SVG/proposals/css-animation/animation-proposal.html

ed: previous discussions indicated that this should be made a spec module on top of svg 1.1, and perhaps later included in svg2

dirk: i could be co-editor

cl: we need someone from MS to take this on

<ChrisL> it would be good to get a co-editor from microsoft, or more involvement from them

ed: i could also co-edit
... we need more feedback from the csswg, i did send this to www-style, but we might need to get this on the wg's agenda too

<scribe> ACTION: ed to contact Microsoft about ISSUE-66, and editorship, and to mail the csswg chairs about the syntax issues for svgattrs->cssprops [recorded in http://www.w3.org/2012/02/13-fx-minutes.html#action02]

<trackbot> Created ACTION-70 - Contact Microsoft about ISSUE-66, and editorship, and to mail the csswg chairs about the syntax issues for svgattrs->cssprops [on Erik Dahlström - due 2012-02-20].
