AE: Link to agenda

10:45:16 [anthony]

10:52:46 [anthony]

AE: Get an idea of our time spent on each topic

10:53:11 [anthony]

... so if our goal is to make a new publication of the test suite then a bit of time will be spent on that

10:53:18 [anthony]

... do we agree on that

10:53:23 [anthony]

CL: Good idea

10:53:56 [anthony]

DS: Put priority on getting whatever needs to be done to get Tiny 1.2 published

10:54:09 [anthony]

... next is SVG in HTML

10:54:28 [anthony]

... third thing is what is the nature of the SVG IG

10:54:35 [anthony]

... should have a short discussion on this

10:54:39 [anthony]

... what can we get from therm

10:54:45 [anthony]

s/therm/them/

10:54:56 [anthony]

... membership policy, what they can do, etc

10:55:17 [anthony]

AE: Discussion of the new WG home page

10:55:30 [anthony]

... also we have XML HTTP request review

10:55:39 [anthony]

DS: Sort of a moving target

10:55:45 [anthony]

... XH1 is in LC

10:55:50 [anthony]

... should review that

10:56:01 [anthony]

... not necessarily in the F2F

10:56:12 [anthony]

AE: So as far as SVG in HTML, how long will it take to do that?

10:56:26 [ChrisL]

(that pdf link has two pages, by the way - page two is the nice to sophia direction)

10:56:43 [anthony]

DS: A couple of us could break off into a scrum

10:57:32 [Zakim]

-ed

+[IPcaller]

10:57:51 [anthony]

AE: I think for the test suite there will a lot of work there

10:58:02 [anthony]

... put 3 or 4 days to it

10:58:10 [ed]

Zakim, [IPcaller] is me

10:58:10 [Zakim]

+ed; got it

10:58:10 [anthony]

... does that sounds like peoples expectations

10:58:14 [anthony]

DS: I would expect 3

10:58:17 [anthony]

... but I could be wrong

10:58:38 [anthony]

AE: We can publish and updated test suite with out an implementation report?

10:58:42 [anthony]

CL: Yes we can

10:59:03 [anthony]

AE: There's no reason to not be able to do one, could be distracting perhaps

10:59:11 [anthony]

ED: Could take a bit of time

11:03:01 [ChrisL]

Meet in hotel lobby at 07:50, I wil ltake you on the tram to the bus staion

11:03:17 [ChrisL]

then we get the 08:15 sophia express, arriving 09:15

11:03:24 [ChrisL]

start meeting at 09:30

11:03:40 [anthony]

Topic: Test Review Status

11:04:18 [anthony]

AE: Try to get people to review tests in spare time

11:04:29 [anthony]

... still some tests on the list that don't have a reviewer

11:05:45 [anthony]

Topic: 1.2 Filter Region Extensions

11:05:46 [aemmons]

http://lists.w3.org/Archives/Public/www-svg/2008May/0014.html

11:06:04 [anthony]

ED: I have had a chance to read this

11:06:08 [anthony]

... not sure I agree with this

11:06:46 [anthony]

... can have filter units userSpaceOnUse

11:07:07 [anthony]

... there is a need to have a filter margins to disappear

11:07:32 [anthony]

... Having margins specified in the mark up is ok

11:08:18 [anthony]

CL: Good for authoring tools to specify this

11:09:08 [anthony]

AE: Do we agree with that and should we reply?

11:09:14 [anthony]

ED: We should reply

11:09:21 [anthony]

... I would like to keep filter margins in the spec

11:09:48 [anthony]

... tools can specify the markup

11:10:01 [anthony]

CL: Think we all agree with you pretty much

11:10:34 [ed]

s/tools can specify the markup/tools can generate the filter-margins markup, and viewers will be able to handle that more efficiently/

11:10:44 [anthony]

ACTION: Erik to respond to Robert regarding the removal of SVG 1.2 filter region extensions

11:10:44 [trackbot-ng]

Topic: feTurbulence clarifications

11:11:11 [aemmons]

http://lists.w3.org/Archives/Public/www-svg/2008May/0017.html

11:11:25 [anthony]

ED: This is pretty much resolved as to what he was asking

11:11:30 [anthony]

... in an email thread

11:11:56 [anthony]

... he was asking what one of the parameters to feTurbulence meant

11:12:10 [anthony]

CL: Do people use that C code, does it help them?

11:12:13 [anthony]

ED: I think so

11:12:34 [anthony]

CL: Is it useful as documentation?

11:12:39 [anthony]

ED: I think so

11:13:01 [anthony]

CL: They decided in the past to document using pseudo code

11:13:22 [anthony]

... don't mind putting it in a separate file

11:13:46 [anthony]

ED: Would like to have Cameron to say something about this

11:13:52 [anthony]

... had look at the filter code in Batik

11:14:12 [anthony]

... looked to me like my interpretation was correct

11:15:15 [anthony]

ACTION: Eric to clarify parameters to feTurbulence as per Robert's email

11:15:15 [trackbot-ng]

Sorry, couldn't find user - Eric

Topic: source-image offset-dimensions control

11:16:01 [aemmons]

http://lists.w3.org/Archives/Public/www-svg/2008May/0018.html

11:16:07 [anthony]

ED: was experimenting a bit

11:16:14 [anthony]

... which part of an image you draw

11:16:19 [anthony]

... in an SVG element

11:16:35 [anthony]

... would be useful to pick part of an image

11:16:45 [aemmons]

http://lists.w3.org/Archives/Public/www-svg/2008May/0011.html

11:16:50 [anthony]

... in image co-ordinates which would be pixels I guess

11:17:16 [anthony]

AE: What feed back did you get on that?

11:17:22 [anthony]

ED: Feedback is positive

11:18:04 [anthony]

... would like to specify percentages of the dimension of the image

11:18:36 [anthony]

CL: so can't you do this in clip?

11:18:38 [anthony]

... you can't do any percentages in the clip and you would have to know the dimensions

11:18:59 [anthony]

s/... you can't do any percentages in the clip and you would have to know the dimensions/ED: you can't do any percentages in the clip and you would have to know the dimensions/

11:19:34 [anthony]

AE: Interesting if it could be animated

11:20:05 [ed]

http://lists.w3.org/Archives/Public/www-svg/2008May/0025.html

11:20:22 [anthony]

ED: Might be possible to do a more general solution

11:20:31 [anthony]

... when referencing an SVG image

11:20:39 [anthony]

... can't override the view box currently

11:20:46 [anthony]

AE: My question is where do you think this would go?

11:20:52 [anthony]

... a future module?

11:20:54 [anthony]

ED: Yes

11:21:14 [anthony]

AE: What kind of module would this be?

11:21:19 [anthony]

... right now it's in structure

11:21:32 [anthony]

ED: Would be useful to discuss how we move forward with the modules

11:21:44 [anthony]

... might be useful to have an SVG Full call module

11:21:53 [Zakim]

-aemmons

11:22:02 [ed]

s/full call/full core/

11:22:10 [anthony]

... certainly a need to add some definitions on top of Tiny

11:22:36 [aemmons_]

zakim, ??p0 is me

11:22:36 [Zakim]

+aemmons_; got it

11:22:38 [anthony]

CL: You mean a whole single module that takes Tiny to Full?

11:23:03 [anthony]

ED: Intro definitions need to be updated and what kind of links as well

11:23:51 [anthony]

AE: If there is a general agreement, do we a place on the wiki to put these new ideas

11:24:16 [anthony]

DS: Use tracker and wiki

11:24:29 [anthony]

... Tracker can document individual issues and wiki can be used to give priority

11:24:37 [anthony]

ED: Would like to get feedback from the interest group

11:25:55 [anthony]

ACTION: Doug to set up a wiki page that stores our ideas for modules

11:25:55 [trackbot-ng]

Created ACTION-2020 - Set up a wiki page that stores our ideas for modules [on Doug Schepers - due 2008-05-22].

11:26:31 [anthony]

DS: What exactly is the first thing I should be putting up here?

11:26:44 [anthony]

AE: The source image proposal that we discussed

11:28:42 [anthony]

Topic: filter primitive subregion and feGaussianBlur

11:28:52 [aemmons]

http://lists.w3.org/Archives/Public/www-svg/2008May/0013.html

11:30:08 [anthony]

ED: I guess he's correct in restricting calculation is kind of ambiguous

11:30:18 [anthony]

... the section he is quoting is quite generic

11:30:49 [anthony]

... also says it has to be treated like a hard clipping region

11:30:59 [anthony]

... not sure if I replied to this or not

11:31:10 [anthony]

AE: No reply to this

11:31:22 [anthony]

... so is this something that would warrant changing the wording?

11:31:53 [anthony]

... is there something we could change to make it more obvious to others?

11:32:14 [anthony]

ED: Could add implementations are recommended to not perform filtering outside of the hard clipping region

11:32:30 [anthony]

DS: I can't imagine that implementations might want to

11:33:03 [anthony]

... we should make it informative not normative

11:33:09 [anthony]

... this is an implementation tip

11:33:16 [anthony]

... not a conformance criteria

11:35:25 [anthony]

ED: The important part is the clipping region

11:36:29 [anthony]

AE: There's probably no point in adding anything, unless it's a really bad problem

11:36:59 [anthony]

DS: We could make the change and respond

11:37:15 [anthony]

ED: There is a second part here

11:37:20 [anthony]

... haven't had time to study that

11:37:26 [anthony]

... that would need to be addressed as well

11:37:40 [anthony]

CL: What it means it doesn't reflect

11:37:47 [anthony]

... doesn't have an edge

11:37:57 [anthony]

... that says now the filter repeats if it is big enough

11:38:56 [ChrisL]

> If the input has infinite extent and is a tile, the filter is evaluated

11:38:56 [ChrisL]

with periodic boundary conditions.

11:39:25 [ChrisL]

surely if its infinite extent then whether it tiles is irrelevant. there can only be one such tile, so its boundaries are never reached

11:39:40 [ChrisL]

check where that sentence comes from, it looks bogus to me.

11:40:19 [anthony]

ACTION: Erik to add informative implementation tip regarding filter primitive subregion and research the second question in Robert's email and respond to that as well

11:40:19 [trackbot-ng]
