I think this property does not influence existing content a lot 21:32:11 shepazu: I think we should let the CSS WG deal with it 21:33:12 heycam: it is late to bring it up 21:33:31 heycam: to inform authors about optimized speed 21:33:31 s/late to bring/worth bringing/ 21:33:55 krit: I am fine with leaving it now 21:34:24 heycam: we leave it and add a note that CSS WG is working on it. If CSS WG is quicker, we remove it and add a reference to it 21:34:59 action: tav to add a note to image-rendering property that CSS WG is dealing with a new version of it 21:34:59 Created ACTION-3480 - Add a note to image-rendering property that CSS WG is dealing with a new version of it [on Tavmjong Bah - due 2013-04-11]. 21:35:06 https://launchpadlibrarian.net/136181479/scaling_test.svg 21:35:21 Tav: ther is a nother issue 21:35:43 Tav: open the image i posted in the mail and change the zoom 21:35:50 s/ auto means smoothing/ auto means smoothing, which is undesirable in at least all 'optimizeSpeed' content I've made/ 21:36:15 heycam: that is the bilienar filtering that you see 21:36:29 Tav: I think it is actually the color spacwe 21:36:36 Zakim, who's noisy? 21:36:46 Tav: one that you see is sRGB, the other is linear 21:36:47 shepazu, listening for 10 seconds I heard sound from the following: heycam (71%), nikos (43%), Tav (24%), krit (5%) 21:36:59 Zakim, mute nikos 21:37:00 nikos should now be muted 21:37:33 krit: isn't it an implementation issue 21:37:50 Tav: yes, but all three browsers do that because they use sRGB 21:38:17 Tav: And I don't think that this is the right thing to do 21:38:43 Tav: in the future when people use GPU it will be easy for themm to switch color spaces 21:39:38 the svg one is using a , is it different if you use ? 21:39:56 cabanier: it depends more on how you scale. I do not think that switching the color space is correct 21:40:14 shepazu: I don't think that is a SVG issue, but more SVG 21:40:22 s/more SVG/more CSS/ 21:40:46 cabanier: I do not think that you change color space on scaling 21:41:02 cabanier: transforms and color space are different thing 21:41:31 Tav: if I zoom in the color should not change 21:41:46 krit: I think this is more an issue of antialiasing, not color space 21:42:15 (is this different for SVG vs HTML? if not, why are we talking about it in an SVG telcon, vs discussing it on www-style?) 21:43:39 Tav: there would definitely be a visible difference on changing color space on scaling and you can not know if you are scaling in a motion or not 21:44:04 s/Tav: there/krit: there/ 21:44:33 cabanier: why specifying it in SVG if you think that is an issue in the implementation? 21:45:32 krit: we should move this to the mailing list and disucss it with the CSS WG 21:46:15 shepazu: I think we should not do our own color stuff, i think it should be in CSS 21:46:50 Tav: If SVG says it is something that we want to do, then we should drive it 21:47:00 shepazu: who is doing the color stuff in SVG 21:47:03 krit: Chris 21:47:15 cabanier: but Tab took over on CSS4 Color 21:48:03 action: Tav produce an exmaple, demonstrating how different color space interpolation effects image scaling 21:48:03 Created ACTION-3481 - Produce an exmaple, demonstrating how different color space interpolation effects image scaling [on Tavmjong Bah - due 2013-04-11]. 21:48:14 Tav: I saw the same issue on filters 21:48:27 krit: makes sense, but depends on the input 21:49:05 Tav: are browsers interestef in color interpolation? 21:49:12 cabanier: yes it is in there 21:49:15 cabanier: CSS4 Color 21:49:21 http://dev.w3.org/csswg/css-color/#color-management 21:49:28 Tav: that would solve some problems that I see with meshes 21:50:39 -ed 21:51:09 cabanier: this is a property that switches between DeviceRGB and sRGB 21:51:58 krit: yes, that is what we have in WebKit 21:52:20 krit: in SVG we have color-interpoaltion that switches between sRGB and linearRGB 21:52:32 heycam: I think color-interpolation should go to CSS4 Color 21:53:16 krit: there is just one problem: SVG is sRGB by default. Implemeentd is DeviceRGB 21:53:30 cabanier: don't think CSS changes 21:53:35 cabanier: that 21:53:56 krit: I think it does, because it has auto, which is DeviceRGB 21:54:02 cabanier: oh 21:55:27 krit: in reality no one implements sRGB but DeviceRGB (all browsers and tools) 21:57:13 heycam: I don' think it says anything about using sRGB by default on images 21:57:30 krit: color-interpolation is not limited to images but effects everything 21:58:25 heycam: you are aying CSS should call it color-interpolation? 21:58:45 krit: yes, but we would need to add auto and would need to say that auto means sRGB 21:59:00 krit: or we say the truth and use DeviceRGB instead 21:59:10 krit: as every implementation does anyway 22:00:51 action: krit to ask CSS WG to use color-interpolation instead (as defined in SVG) with the addotion of auto 22:00:51 Created ACTION-3482 - Ask CSS WG to use color-interpolation instead (as defined in SVG) with the addotion of auto [on Dirk Schulze - due 2013-04-11]. 22:01:23 action: krit to figure out if we should use sRGB or DeviceRGB on SVG 22:01:23 Created ACTION-3483 - Figure out if we should use sRGB or DeviceRGB on SVG [on Dirk Schulze - due 2013-04-11]. 22:02:00 topic: meeting with IDTF 22:02:04 s/T/P/ 22:02:21 s/IDTF/IDPF/ 22:03:00 shepazu: I would not be able to go there 22:03:07 leaverou has joined #svg 22:03:26 leaverou has left #svg 22:03:27 shepazu: IDPF is happeing at media campus 22:03:35 s/media/Keio Mita/ 22:03:43 shepazu: 25min appart by train 22:04:00 shepazu: agenda is about internationalization issues 22:04:54 -Tav 22:04:59 shepazu: are any of you interested in this topic? 22:05:09 s/IDTF/IDPF 22:05:21 heycam: you said that they may have interest in SVG and want our opinion about that? 22:05:35 +Tav 22:05:44 :-) 22:06:13 shepazu: I think the focus is on electrical publishing 22:07:49 richardschwerdtfeger: It is really important in MathML 22:08:00 richardschwerdtfeger: I'd like to have a open format in documetns 22:08:11 richardschwerdtfeger: I would like to see them SVG2 22:08:21 richardschwerdtfeger: which is important in the future 22:08:32 richardschwerdtfeger: ARIA and other accesibility things 22:09:51 shepazu: I am not convinced if the timing is right 22:10:04 shepazu: and especially in the context of this meeting 22:10:19 shepazu: the focus on internationalizing 22:13:25 resolve: we meet from monday to wednesday 22:14:07 shepazu: I will talk with the organizers 22:15:12 shepazu: another option is to invite them to one of our sessions 22:15:22 by the way, I started adding some details for the Tokyo F2F to http://www.w3.org/Graphics/SVG/WG/wiki/F2F/Tokyo_2013, more hotel suggestions etc. to come 22:15:39 cool 22:15:49 -birtles 22:16:11 shepazu: why not invite some to a telcon 22:16:28 action: shepazu to invite IDPF people to a SVG telcon 22:16:28 Created ACTION-3484 - Invite IDPF people to a SVG telcon [on Doug Schepers - due 2013-04-11]. 22:17:23 topic: CSS4 Color and merging SVG Color 22:17:49 -Doug_Schepers 22:18:13 krit: tab sugeested to pick up SVG color things to CSS4 color 22:20:05 krit: ICC color profiles have been in SVG1.1 already.
