Web Animations

<birtles>
[41]http://www.w3.org/Graphics/SVG/WG/wiki/F2F/Sydney_2012/Agenda/An
imations/WebAnimations

[41]
http://www.w3.org/Graphics/SVG/WG/wiki/F2F/Sydney_2012/Agenda/Animations/WebAnimations

BB: the last thing I wanted to put forward was the idea of making
this Web Animations spec

… which covers both SVG and CSS animations

… and as was suggested, I think by Dean or someone, also a JS API

… in addition to what we already have

… you can see the basic ideas there [in thel ink]

… there'd be two syntaxes, and along the lines of Filter Effects,
it'd probably be that the features available in the CSS syntax would
be more limited than those available in the element syntax

… that's the basic idea

… I've written a few very draft ideas, already just talking with Rik
I think I've overhauled large parts of those ideas already

… I'll pick out a couple of points

… one would be that animation should be able to target more than one
element, SVG Animations are limited in that regard at the moment

… e.g. we might have a select="" attribute

… that's one example of the sort of things I'd add

<cyril>
[42]http://www.w3.org/Graphics/SVG/WG/wiki/F2F/Sydney_2012/Agenda/An
imations/WebAnimations

[42]
http://www.w3.org/Graphics/SVG/WG/wiki/F2F/Sydney_2012/Agenda/Animations/WebAnimations

… also you can use an animation defined using an element syntax,
reference it using the CSS animation-name property

… also talked with Rik and Vincent about how SVG animations are
limited in that they can only target one attribute at a time

… if you want to target more than one, you need another animation

… that's also something we could possibly address here

<TabAtkins> This is relevant to my interests, and I'd like to be
involved in seeing it through. (Shane too, if he's not there today.)

… I have a couple of draft ideas here, maybe a semicolon separated
list of attribute names

… that idea of being able to target more than one attribute/property
at a time might be useful

… especially with aligning with CSS animations

… one issue that I think I'd like to think about is backwards compat

… I originally was proposing something separate to what we already
have in SVG animations, deprecating what we have and replacing it
with something that is not backwards compatible

… it's more aligned with CSS animations, but it draws on the
learning from SVG's SMIL animation heritage

… that was my initial proposal

… but I think Cameron suggested that he'd like to see if we could
keep backwards compatibility

… that's one of the bigger questions

… is it ok to make something new, and deprecate the old

… or is it important to build on what we have, recognise that that
might limit how much we can simplify and align with CSS

… maybe that's something we can't answer right now

… we need to do more investgation

… but I'd be keen to hear everyone's views on backwards
compatibility and how important is that, how feasible is it to
develop new elements

ED: I don't think we can drop current SVG animation support from our
implementation

… animateTransform is used, animateColor not so much, animateMotion
is useful but not used so much

BB: I'm thinking about deprecating <animate> as well

… so this proposal is for something completely separate

… there are subtle differences between CSS and SVG animations

… such as rounding behaviour is different

… if we want to keep our existing syntax, how can we align with CSS
and keep backwards compat

… there may be a way to do that, we could have a flag that triggers
the different behaviour

… but the alternative would be to come up with new elements

RC: maybe you could define it in such a way, that someone can write
a library that implements the new syntax based on the old syntax

BB: the main situation I'm interested in is when you don't have
script

… that's when you really need declarative animation

CC: I like some of the ideas

… having one element for the animation, <animate> only, that's fine

… I like adding selectors, possibilities to target multiple
attributes

… but the general idea of redesigning something new, that's the
thing I don't like

… I think we could start with the <animate> element and augment it

… so it's easier to use

… extend its behaviour so it can do <set>, etc., but not start from
scratch

BB: what do you think about naming things?

… one example here is iteration-count

… in SVG it's repeatCount

CC: it's fine, we can duplicate the attribute if we want to

BB: is it fine to allow also iteration-count and define how it
overrides with repeatCount?

ED: the only example similar to this I can think of is xml:id and
id, which wasn't too popular

CC: personally I wouldn't mind having different naming

… as long you don't have to store the two different attributes

CM: I think you would have to though

… the DOM would require you to

BB: you could define iteration-count, and if both are used on the
element then iteration-count wins

… the syntax might differ too, indefinite vs infinite

RC: why would you not just make the syntax the same?

… and the name?

[iterationCount vs animation-iteration-count]

CM: I don't want to break the identity between presentation
attribute names and property names

BB: if we match the names exactly, it forces you to have the same
behaviour and parsing

VH: as the CSS properties?

BB: yes

CM: which might be a good thing

<TabAtkins> If it's desired that we have identical names between CSS
and SVG, that pretty much requires matching CSS at this point, given
relative usage.

CC: CSS Animations is still a draft, right?

CM: there is content out there

VH: still prefixed though

<TabAtkins> But I don't think it's a good thing to require "animate"
prefix on every attribute of an <animate> element. The prefix
namespaces the CSS property, but the *element* namespaces the
attribute.

TabAtkins, yeah, I think that's Brian's argument. OTOH there are
cognitive advantages to using *exactly* the same property
names/values as CSS.

<TabAtkins> CSS is almost certainly *not* able to change its names
at this point, unless there's a major problem. "To match an
unwritten SVG proposal" isn't a major problem.

TabAtkins, are implementations deployed that use unprefixed names?

(or content?)

<TabAtkins> No unprefixed impls yet, but there's unprefixed
*content* out there that we'd like to match unless there's a good
reason not to, plus tons and tons of tutorial and instructional
material using the current names.

CC: it's frustrating that CSS animation is not more aligned with SVG
animation on simple things like whether floor or round is used for
integer interpolation

VH: as a group, we should document these issues, send them to the FX
taskforce

… say we feel they should be aligned, request a change to CSS
Animation

<TabAtkins> Cyril: Blame Apple for coming to the WG with a
fully-formed and implemented proposal instead of starting discussion
early. :/

CC: I can understand they don't want SMIL intervals etc., but in the
spirit where you want to round trip between one and the other...

VH: Brian could you draft a list of things we ask of CSS Animations
to change, like the rounding stuff?

<TabAtkins> (Details like rounding *are* potentially changeable on
the CSS side.)

BB: with what scope?

… it's almost impossble to change names, rounding behaviour there is
some hope of changing

VH: the message could just be "here are differences" and a pointer
to your document

BB: I think the rounding is the most significant issue

<TabAtkins> (Names can *often* be changed, but Animations are pretty
mature at this point. They should have been CR *long* ago, but the
editors stopped working on them.)

CM: we should identify the features that prevent us from
extending/aligning while keeping the same name <animate>

<scribe> ACTION: Brian to identify things that prevent us from
having <animate> align with CSS Animations, and present them as
change suggestions for CSS Animations in FXTF [recorded in
[43]http://www.w3.org/2012/01/13-svg-minutes.html#action01]

<trackbot> Created ACTION-3223 - Identify things that prevent us
from having <animate> align with CSS Animations, and present them as
change suggestions for CSS Animations in FXTF [on Brian Birtles -
due 2012-01-20].

BB: another minor one is indefinite vs infinite

… that's something we could fix on our side

VH: indefinite is used for begin="" as well

BB: that's where I think we should deviate from SMIL

CC: we should encourage authors to use the updated syntax, but
existing implementations would still need to support the old stuff

… having a note in the spec for authors about this would be good

BB: the rest I think we talked about yesterday, obviating the need
for animateTransform, animateColor

<TabAtkins> (We have similar cases in CSS where some legacy syntax
is explicitly allowed as an alias, but authors have a MUST NOT
requirement against using it.

VH: the reason we had for animateColor is that there are properties
that take colors and fill patterns

… animateColor indicates that they're just colours

CM: you don't need to indicate that though

… you know you have two colour values, it's clear how to interpolate

CC: for animateMotion, in GPAC the way I implemented it is just
using <animate> with a pseudo attribute called "motion transform"

BB: that's the direction I'm interested in, partly because if we
want to introduce motion animation to CSS animation, it would make
it easier

<TabAtkins> I think that's a good approach.

… CSS Animations doesn't have separate <animate>, <animateMotion>,
etc.

… if we can do it just with <animate>, it's easier to bring across
to CSS Animations

CC: in the page it says it should also be possible to animate all
colour stops of a gradient at the same time?

BB: yes, you can't do that in SVG

CM: but you will be able to

… because we will support css3-image

BB: the main thing I want to get out of this session is some
consensus on direction

… and then hammer out details later

… Vincent's already agreed to help me with that

VH: I have a question on <set>

… there was a proposal to have a timing element like <set>, and
instead of being an animation element like SMIL, it would actually
do a real DOM setAttribute operation

… one difficulty would be what happens if you have two of these,
you'd need to define priority

… it could be good for non-scripted situations

… but that's a separate discussion

BB: moving on, I was thinking of adding an element for timing
containers, but I don't think that's such a great idea now

… one suggestion was to add a timeContainer attribute on SVG
container elements like <g>

… I'll work on that

… but some way of specifying par/seq time containers is what I'd
like

<cyril> [44]http://wam.inrialpes.fr/timesheets/

[44] http://wam.inrialpes.fr/timesheets/

BB: I would like to work out how to align events

… maybe making TimeEvent a subinterface of AnimationEvent

VH: do any implementations let you use SVG animations target HTML?

BB: yes, Gecko lets you target properties of HTML elements from SVG
animation elements

ED: Opera doesn't, but we could

BB: that's another question, whatever we define it should be able to
target HTML as well

… and then for HTML, whether targetting properties is enough there

<cyril> Tab, does WebKit allow you to animate HTML properties with
SVG animation elements ?

… and think there's a bit of opposition to targeting HTML attributes

<TabAtkins> I highly doubt it, but it would be easy to test.

CM: I want to get a sense of whether HTML folks would want this new
<animate> to be able to be put directly in HTML documents without
SVG around it

BB: we can start with just allowing it in SVG, and if it proves
useful, see if HTML folks want to allow it directly

… a different discussion perhaps, what to do with DOM storage

… the messy baseVal/animVal

<TabAtkins> Burn it with fire?

… I wonder what is useful to authors

… I find I just use animVal

ED: I find baseVal more useful because you can read and write to it,
unlike with animVal which is readonly

CM: at least when you're modifying you need baseVal

BB: but yes, what do we need out of an SVG DOM APi

<TabAtkins> I find that I don't use either, and then things break,
and then I cuss until I remember and choose one to use
semi-randomly.

CM: we will be having a broader discussion about SVG DOM improvments

… I don't think those improvements will impact the rest of your
proposals here

<shepazu> I suggest we get in touch with Mike Bostock, DmitriB and
other animation script lib authors to ask what they want to see in
an API

BB: seems like we should move forward with this then

CM: I would like to hear what the non-SVG FXTF people feel though

shepazu, yes good idea

RESOLUTION: We will work on a proposal for a Web Animation spec that
underlies SVG and CSS Animations, and write up a summary document on
which features ought to be supported in CSS Animations with use
cases and examples

raised

<trackbot> [48]http://www.w3.org/Graphics/SVG/WG/track/issues/2281

[48] http://www.w3.org/Graphics/SVG/WG/track/issues/2281

<cyril> Doug, do you remember anything on this issue that you
raised?

ED: are paced animations hard to write at the moment?

BB: it's mostly just for motion animation at the moment

… not sure what the particular need is here

CM: so this would allow specifying a speed for the motion animation

… since you don't know what dur you would specify

BB: my guess is that cases where you don't know what the path length
is, is when you are doing scripted path generation

<shepazu> [[ pace="10px/1s" ]]

BB: and if that's so, you can just do getComputedPathLength [or
whatever it is]

DS: yes it's true you could use that method, if you have a <path>

… again that calls for script

… the path might change, then you need to do getComputedPathLength
every time

… if the path is moving, and you want the animated object to move at
a steady pace it will be more of a pain

… also if you have an animation that is not along a path, you could
not do that

… e.g. if you just want to move an object to the right [at a certain
speed]

… you could also see this being used when animating colour, if you
want an animation to be synced with another of a in certain duration

BB: I was thinking when you have <mpath> that's interesting, because
the target path might be changing outside of your control

CM: is it a problem that instance times change because a path length
will change, and an animation along the path is specified using a
speed?

BB: instance times already can change in the SMIL model, that's one
of the more complex parts of SMIL

… maybe it would be bad that instance times get updated every
animation tick

… can <mpath> target an animated path?

ED: yes

CM: probably not the most important feature, but let's accept it
(and prioritise later)

BB: this would introduce some coupling between the animation and the
timing model

… it's not what you normally do, but if it's useful it might be
worth it

RESOLUTION: We will support motion animation of a specified speed in
SVG2.

SVG UI enhancements

heycam: we discussed this before and decided to not do UI in the
zoom/pan features.

ed: this is a bit different.

cl: this is not something we should be adding.
... it is a huge amount of work and not necessarily what people
need.
... the zoom/pan we talked about and we may add through the
'controls' attribute to switch it on/off.
... this was rejected earlier.
... for layers, we already have groups and you can switch on/off
layer by toggling visibility.

RESOLUTION: SVG2 will not address the "Basic SVG UI enhancements"
requirement.

[50]
http://www.w3.org/Graphics/SVG/WG/wiki/SVG2_Requirements_Input#Specify_that_unknown_elements_are_treated_as_.3Cg.3E_elements_for_the_purpose_of_rendering

<ed> the layer UI, that's <g>, which already has UI if you use
browser debugging tools, e.g dragonfly, firebug or whatever

unknown elements treated as <g>

ed: this is asking the opposite of what we require. We say it is
display none, so the children do not display.

<TabAtkins> I suppose that's like HTMLUnknownElement acting like
<span>?

heycam: what is described here is similar to what HTML does.
... I do not think this proposal, or the current way, are completely
free of what content is out there.

ed: I do not think this is a good idea.
... I think that not showing anything is reasonnable.
... if you want so kind of fallback, we could do it some other way.

cl: this is related to the switch requirement later on.

ed: we resolved to fix the issues with <switch>.
... by saying the requiredFeatures on unknown elements is still
looked at.

cyril: the use case is fallback for connectors.
... it is not a valid use case because an old browser, when
encountering a connector, will not render the inside of a connector,
and new browsers, which know connectors, will render them.

cl: I have preference the <switch> way to provide a fallback (rather
than the children way of HTML).
... I prefer the test statements that <switch> provides.

heycam: but people dislike feature strings

<ChrisL> as long as the tests work, which is not really the case
with feature strings

heycam: I slightly hesitate to change the behavior, but I do not
mind to mind.

ds: I can see both ways.

cl: rendering children has not worked well in HTML with <object>. In
some cases browsers rendered the whole lot, in some cases they
rendered nothing. That was both an implementation and specification
issue. In general, it makes it hard to see what the different
alternates are. I would rather have different trees that are the
alternates.

ds: has it become an anti-pattern.

cl: it has become an anti-pattern.

ds: I do not think it is an anti-pattern. New elements are just
treated that way in HTML5.

cyril: I think it works well in HTML because of the CSS box model.
In SVG, you need explicit positioning of the object. If you way it
works like a <g>, do you need to accept the transform attribute.

ds: I do not understand your point.

cyril: if you do not know an element and render its children instead
of that element: it makes sense in HTML because it will not disturb
the whole layout because it is dynamic. In SVG, where everything is
positioned, I think it distrubs the whole rendering.

cl: iin CSS, the default styling for unknown elements is display:
inline,which works ok for text

ds: in the case of <connector> and it does not render as a
connector, but if inside that you have a path element that draws the
connector, then you have a fallback. The transforms would be in the
path or in the subtree.
... in HTML, if you have something that is replacement content, it
make a box around itself. In SVG, it is just rendered.

heycam: I think it is plausible to create fallback content that
renders fine.

cc: I do not know how to explain differently. We are talking about
elements in the SVG namespace?

cl: what happens with an HTML parsing? Isn't it going back to HTML?

cmc: I think it stays in SVG.

cc: if the elements are metadata, we do not want that to be
rendered.

ds: you could put display:none, or put it in a <defs> element.

<ChrisL> what about <newFooElement><title>text</title><desc>blah
blah</desc> .... </newFooElement>

cmc: in this example, <title> and <desc> do not get rendered.

ds: if we did not have <textPath> and added your proposal, and then
we added <textPath> then the text under it would display.

cmc: I just tested the HTML5 parser, the unknown element gets put in
the SVG namespace.

cmc: in HTML, nearly all elements are container elements. In SVG,
most elements are not container elements. It's more likely that a
new element is not going to render its children in SVG>

ds: I see what you are saying, but is that a reason to keep the
current behavior.

cc: I can go either way.
... is there content outside that relies on unknown element not
being rendered?

cl: we encouraged people to put elements in their own namespace. In
practice, people did not do that.
... I suspect we would find usage of that.

ds: I think it is compatible with HTML and it gives us an
extensibility mechanism that does not require using <switch>. It
lets people do content in an intuitive way they are used to,
regardlesss of how it worked in the past. It is a change for SVG,
from SVG 1.1
... it is not clear if it is beneficial for all UA. From SVG2, we
could use that extensibility mechnism.

ed: I am not sure. To me, it would be confusing. Some UA would do
the old way, some would do the new way, and then you would need a
script to deal with the difference. What is hte benefit?

ds: you would have to do a short script.

ed: but you could do a scirpt to do what you want.

<TabAtkins> Note that, for most authors, the only UAs that matter
are browsers.

ds: I think that script would be short lived (3-5 years). As opposed
to 'everything in the future"

ed: I do not know how much would break.

cmc: we could resolve for it under the provision that it does not
break existing content.

cl: it is tied to the item on <switch> and not using feature string.
... I share ds 's concern that it does not work currently. I use
<switch> a lot, but this is not the way I would like to do it.

ds: there are places where I would use switch, but I think that it
would be handier to not have to use it for simple casess.
... I do not mind if we revisit this later. I would like for us to
accept this and then reject it later and reverse if we find it is a
bad idea.

cc: we could put it in the spec. and see if people think it will
break their content. We could mark it at risk.

cmc: may be we can mark features that we are not entirely sure
about.

ed: it would be nice to have more examples that show how it might be
used.

cl: it would be find as a paragraph in the extensibility chapter.

ed: it would be good to get this to work especially in the SVG in
HTML context.

ds: it fits well with the web component model. Because we would not
have to explicitly add the elements that they are talking about.
They would simply work the way they are.

cc: let's not argue anymore. We have a consensus.

ed: I would be surprised if you could write a script that makes
things work in older browsers and new ones. It is more complicated
because you'd need to modify the DOM structure to get it to render,
and that might affect other things too

cl: we should find out how hard it woudl be for shims to work.

ed: I would like to see a fallback script to understand how hard it
would be.
... we could write a fallback script right now to see how it works.
... I think we could investigate it and accept if there are not
issues.

<ChrisL> vh: torn on it, can see dougs point butits not a high
priority item

RESOLUTION: Accept having unknown elements treated as <g> for the
purpose of rendering. However, the groups wants community feedback
on how much content would be impacted.

bridge the old and new behaviors for content under unknown elements.

Specify how SVG graphics and text are copy/pasted.

<ChrisL> [54]http://www.w3.org/TR/SVG/mimereg.html

[54] http://www.w3.org/TR/SVG/mimereg.html

cl: if you look at the media type registration, I added stuff about
copy/paste in response to feedback saying we needed to specify what
happens with clipboard.
... the Windows one is a string. The Mac one is saying that SVG is
both an image an xml.

<ChrisL> Macintosh Universal Type Identifier code:

<ChrisL> org.w3c.svg conforms to public.image and to public.xml

cl: is this somethign the platform needs to do.
... if pasting into an editor, you could do useful things with it.
... it is not fully specify, but there is something there.

ed: I think we should not make it a requirement. It should be a
'should'. I think the UA should be left to decide to rasterize or
not.

vhardy: I think that most clipboards allow you to copy in multiple
formats.

ed: right.
... in the way it works on Mac, you announce which formats you can
generate, and the receiving application says the one it prefers,
which is then the one generated by the app (from which the cut
happens).
... I think it is fine to make recommendations, but I do nto think
we should have a hard MUST requirement.

<TabAtkins> I disagree - web applications need to know what the
format of the data is on the clipboard if they're going to deal with
it.

cmc: I do not think we should be requiring special UA behavior for
how content is selected.
... there is a clipboard API spec, and there is a way to put things
in the clipboard with type and content.

<heycam> [55]http://dev.w3.org/2006/webapi/clipops/

[55] http://dev.w3.org/2006/webapi/clipops/

cmc: this clipboard API allows you to say 'copy this string to the
clipboard and interpret it as SVG'.
... I think someone should look into the existing API to see if we
need to specify anything additional.
... it may be outside of our scope to add anything. We may need to
suggest rasterization.
... I am happy with the requirement saying how applications should
behave if pasting SVG content in them.

cl: yes, but it should be more guidance.

RESOLUTION: Accept the requirement on how SVG graphics and text are
copy/pasted for the SVG2 specification, considering both
non-normative and script API related requirements.

ed: there might be different behaviors between devices and user
agent. For example, on a mobile you might want to copy just the
text, and not the SVG as you would on a desktop.

consider removing the requirement for @widht and @height for
<foreignObject>

[56]
http://www.w3.org/Graphics/SVG/WG/wiki/SVG2_Requirements_Input#Consider_removing_the_requirement_for_.40width_and_.40height_for_.3CforeignObject.3E

cl: for widht/height is put 'no' in the document because the box
model needs the values. There is no automagic sizing.
... but, if we are unifying the width/height properties with the
width/height attributes, we could specify them with stylesheet,
which would be fine and satisfy the requirment.
... the request is to have them not specified, and have that does
not work.

cmc: isn't there shrink wrapping on absolutely positioned elements?

vh/cl: yes.

cmc: couldn't we have the same behavior for <foreignObject>?

cl: I guess we could.
... yeah, we could specify it that way.

cmc: ed has an ACTION to propose something.

ed: I think it would be nice to have that behavior.

cmc: if you want to include HTML content and you do not know how big
it would be, that would be useful.

cl: if we want to rely on the shrink-wrap behavior, then that is
fine.

cmc: I would be surprised if content rely on the widht/height in
foreignObject defaulting to zero and not displaying if zero.

cl: it needs to be more speced out, but more tractable than I
originally thought.

ed: I think we should accept the requirement.

cmc: I agree.

RESOLUTION: Accept the requirement to remove the requirement to have
@widht and @height on foreignObject.

cl: we definitely need to do this. We changed the syntax twice.

... I think <switch> is fine, but the feature strings need to be
totally reworked.

onsider_treating_audio_separately_to_graphics

[60]
http://www.w3.org/Graphics/SVG/WG/wiki/SVG2_Requirements_Input#Consider_treating_audio_separately_to_graphics

cl: we tried to do this in 1.2 tiny time frame. We had lots of
discussion on display:none and visibility:hidden impacting audio. In
general, we need a way to control audio separately and
display/visibility do not seem to be the right controls. I would
like to look at the HTML5 behavior.

cmc: I am wondering if there is a css property to set the volume.

<TabAtkins> There is not, but there could be.

<TabAtkins> We could either yoke this to Speech (probably not a good
idea) or make a new one.

cl: there was in the aural CSS but there is not in the new work on
text to speech done by Daniel Weck.

<ChrisL> tab, prefer the newone

<ChrisL> and in tiny..2 we had an audio-level property

cmc: we need to define how we turn audio off. I am not ready to
accept any specific proposal yet.

RESOLUTION: SVG2 will provide a way to control audio level and
playback.

http://www.w3.org/Graphics/SVG/WG/wiki/SVG2_Requirements_Input#Consider_adding_method_to_return_array_of_declarative_timeline

cmc: this relates to the scripting api for animation and we should
deal with this as part of the Web animations work.

cl: I am not clear on what is asked.

cmc: he is asking to get the timeline information.
... I would be in favor of exposing more information than we do
currently about animation.

RESOLUTION: The WebAnimations proposal will provide an API to get
animation timeline information (i.e., current state of the timing
engine, running animations, pending animations , frozen animations
etc...). SVG 2 will not address this requirement directly.

Consider adding API for saving and restoring SVG state.

<cyril> Scribe: cyril

<scribe> ScribeNick: cyril

CM: as part of that, to get that to work in FF, you can construct a
data url out of the image and draw that in the canvas

VH: a couple of months ago, it didnt work in webkit

CM: in the recent builds, it works

ED: you cant have anything external

VH: why does it have to be a data url

CM: because drawImage takes an HTML image element and that can only
reference an entire document
... there was a recent fix in FF
... regardless of whether that works, if you want to do it by
script, you'd want to serialize the current state

<ed> s/you cant have anything external/you cant have any external
references AFAIK, so if you wanted to draw <svg><image
xlink:href="foo.png"/></svg> into a canvas element then it would
probably just ignore the external reference/

CM: including the computed style of every property and the animated
value of every attribute

VH: didn't we talk about XML serialization before

ED: it doesn't give the animation state

CC: you could use getPresentationTrait

CM: yes or using animVal, it shouln't be difficult

VH: CanVG was parsing the SVG and making rendering calls, because
that wouldnt make the canvas dirty

CM: I would say no to the req because it's not hard to do in a
script

RESOLUTION: SVG 2 will not add an API for saving and restoring the
SVG state

http://www.w3.org/Graphics/SVG/WG/wiki/index.php?title=SVG2_Requirements_Input&section=119

cl: we talked about it earlier and agreed it was useful.

cmc: I am not sure if a dedicated API is needed. In HTML, people
just create an Image, set its source, and then query the
widht/height when loaded.

cl: because of our earlier decision on auto size images, this will
work.

cmc: it is easier in HTML because the DOM is better.

cl: this should be addressed with our DOM work.

RESOLUTION: SVG 2 will not provide a separate interface to get image
intrinsic size because it will be possible to query the size on the
SVG image elements.

ed: might be good to pull those together
... get the two requirement together

cm: that was in the mapping discussion of the first day

ed: it might be nice. How difficult is it?

cm: viewbox is not exposed as a matrix
... currentscale/currenttranslate provides one that is seperate from
the viewbox

does it make sense to keep distinction between zoom/pan and the
viewbox

cm: what would these new methods affect?
... we can accept the requirement to say something to make it easier
to get to zoom/pan

resolution: svg2 will make it easier to write a zoom/pan widget.
possibly by adding convenience method to get scale/transfer

<heycam> s/transfer/translate/

(discussion on panning and zooming)

bb: is up to the browser to optimize the behavior?

cm: yes
... suspendredraw is not good for situations where you only want to
redraw a certain region

[70]
http://www.w3.org/Graphics/SVG/WG/wiki/Requirements_for_Mapping#API_for_smooth_transition_action_of_zooming.2Cpannning.2Crotating

<stakagi> Please give the comment to this subject.

<stakagi> This is another things about smooth transition.This data
is about 10MB of huge SVG file. Originally, such a data is not
suitable in terms of size. But I often look at such a data as a
business-use of GIS or CAD data and they often tests the usability
of these data using SVG viewer (browser) without tiling. Please see
the zooming and pannning transition action. As for this example,
redraw is performed also in the midst of the transition. On the
other hand , t

<stakagi> his is not performed redraw (suspendRedraw-like). If we
can built such UI, SVG is usable in this usecase. First, should such
a transition effect be controllable by javascript? Is it suitable to
use what kind of application programming interface?

cm: at some point it is up to the browser to optimize the movements
of shape
... in this case, if you set a clip when you start the panning and
then just change the transform, hopefully the browser can optimize
that

ed: this is work we did last year:
[71]http://www.newdesignworld.com/press/story/470436
... this is a press release talking how we optimized the browser

[71] http://www.newdesignworld.com/press/story/470436

cm: file a bug with the browser if you find a case that is slow

bb: we did some optimizations too

Align with CSS Value and Units

resolution: we already did that

Gzip-compressed svg in data URIs

cl: it would need to be an update to the rfc that defines the data
URI

resolution: this is outside of our charter. out of scope for SVG2

Deprecate baseline-shift and use vertical-align instead

cl: I can see it but they are not quite the same
... we should go with what CSS is doing

cm: I agree.

cl: I want to get rid of it

resolution: we will deprecate baseline shift and use vertical align
instead in SVG2

Media elements in SVG need ability to associate captions and
description

cc: we already agreed to do that in HTML5
... I don't like this because it makes it hard to overlay graphics
on top of video

cm: why is that?

vh: this is why I thought that you could do this with webvtt

... I know that people are using that certain application

<cyril> for instance in electronic program guids

<ed> the EPGs i've seen have all used javascript

<vhardy> vh: I think that declarative animation is useful and that
having timing tied to events is one of its key features. Therefore,
I think we should be able to tie in UI events, animation events and

definitely have a way to tie in keypresses to animation timing.

<ChrisL> i think the plan is to not meet at svg open as its too
close to tpac, butto meet in july instead

<ChrisL> so seattle in July could be good (Adobe or Microsoft could
host)

resolution: let's meet in July 25-27 in Seattle and TPAC in November
