This is not a only problem. srcset allows UA to pick any image density regardless of actual screen density, so e.g. Safari on iPhone 4 on GPRS/EDGE connection could download 1x images, instead of 2x. UAs are also free to download 1x image first, and then 2x image after onload, etc. Declarative nature of descriptors, as opposed to imperative MQs, allows UAs to innovate in this area and come up with new uses that authors didn't predict/express in MQ. The syntax allows addition of "KB" descriptor later, which — assuming UAs will figure out how to measure actual bandwidth well enough — will allow even more sophisticated selection based on file size (rather than only 1x/2x scale factors which are only a proxy for the file size). (and that's not simply a matter of adding bandwidth media query) and has no mechanism to specify scaling factor for intrinsic sizes of images. Not actually sure what "intrinsic sizes of images" means. A default size of the image when you don't specify any size in HTML/CSS. To take advantage of 200dpi displays you need to tell UA to render a X px image at X/2 CSS px. Explicit width/height breaks adaptive mechanism. I see no difference between the end result of either syntax. Both approaches fail utterly in abstracting the query from the mark-up, which means both approaches are suited only to individual images. True. An URI template can be added later to either solution. The current URI template proposal is limited. I've pointed out few cases for which a single global set of breakpoints is not sufficient. I'd be nice if you tried to extend the proposal to support those cases as well (e.g. {case} → {case:category} and define breakpoints per category such as 'sidebar', 'gravatar', etc.) And has same limitations for DPI adaptation as media>. There are two categories of use-cases ("art-directed" and "dpi/optimization") and is suited for only one of them, so please don't frame the decision as "discarding" of a perfectly good solution, as it wasn't. Picture dealt with both of these by simple use of the pixel density media query - i.e, in exactly the same way CSS already does it. I do not understand your argument. This will only choose between large pixelated image and small pixelated image, and will not make use of high display density. I've explained it in more detail previously (using srcset as an example, but it all applies to min-device-pixel-ratio: MQ as well) http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2012-May/036051.html -- regards, Kornel Lesiński

Re: [whatwg] Features for responsive Web design
You have to understand that the idea was not the result of idle thought. We went through a *lot* of thinking to reach that point, and so it's not actually an attachement to that idea so much as *we know* that idea inside out, what it does, what it doesn't, and why it's like that. We had thought about it from a lot of angles, thrown everything we could at it, and determined that was the most robust, familiar, and flexible solution out of half a dozen possibilities - each of which was under similar scrutiny. Then along comes srcset - which has not been subject to the same scrutiny by that group. So *of course* it's getting questioned hard, and *of course* is being held as answering the needs best. Until srcset has been properly discussed, inspected, picked apart, and subjected to the same level of scrutiny as was, it's not the trusted thing that is. Make no mistake; this is not a pride or attachment thing, this is a knowing the reasons thing. I personally don't think answers things well enough, nor do I think srcset does. Not for general use cases - but for specific one-off use cases, each has benefits. Personally I'm coming around to a refined version of the srcset idea rather than after some clear explanation. But, again, I only see it being appropriate for one-off use cases - singular special-case images within a page. I don't think anyone has yet come up with a good enough general purpose solution that avoids contaminating the mark-up with design-dependent properties which will all be invalid come a re-design - that to me is not acceptable. The closest I've seen that could possibly address that limitation is variables, but that has it's own issues and does not answer the same use-cases as srcset or . -Matt On 18 May 2012 16:40, Andy Davies wrote: > On 18 May 2012 15:28, Glenn Maynard wrote: >> >> Only if there are actual problems solved by doing so, which there don't >> seem to be.

The other proposals have been knocked around by various parties who wanted to solve a problem, they had time to discuss it, digest it and see how it grew to meet their needs. Now srcset was dropped on them as a surprise, they're still trying to understand it, they keep being re-assured it meets their needs but no-one who developed the srcset proposal has really come out and explained to them how it meets their needs so they keep asking questions... I wasn't involved in the picture discussion so have no particular attachment to it, I think both picture and srcset have problems in that they move breakpoints into the markup, srcset's "microsyntax" is pretty horrible and the picture syntax has issues too. The thing that really astounds me about the responsive/adaptive images hullabaloo is: The responsive image problem has been discussed for at least a year with plenty of ideas / workarounds floated around (only got to look a slidedecks form Mobilism, Breaking Development etc. for this) yet WHATWG seemed pretty unaware of it. When WHATWG did decide to do something about it they just dropped it on the people who wanted it by surprise without talking to them first even just to say "this is our proposal, this is how we think it solves your problem, what do you think?" I can understand why some of the "authors" are upset and I still thing the srcset needs explaining clearly rather than them having to chew through the spec. Cheers Andy
[whatwg] Canvas: imageSmoothingEnabled not part of the state stack?
Looking into some of the features recently added to the canvas spec, I noticed that imageSmoothingEnabled wasn't added to the list of attributes saved and restored in the canvas state (in sec. 4.8.11.1.1). This also seems to be the case for the new line dash parameters. Intentional, or oversight? Stephen

It's the same in those two, but it's not really rem - it's the initial font size, just like in Media Queries. (rem is the size of an em on the root element, which depends on style data.)

I wouldn't be surprised if there are, but whoever thinks they will have such use cases should state them clearly so that the design takes them into account. One use case is manipulating content in a contenteditable area, e.g. in a Rich text editor. A JS-based online editor such as TinyMCE or KTML may want to offer some kind of GUI for alternative sources. I am not sure whether this is a very important use case, as authors of online editors are usually JS experts and capable of writing complex string operations, too; but I assume the use case is at least valid.

Re: [whatwg] Bandwidth media queries
I think we may be talking past each other, as I don't see how your answers address the problems I'm trying to highlight. It's not enough to say it's a hard problem. It's not going to solve itself. If you say media queries can be useful for bandwidth/quality use-cases, you need to actually specify how can they work. I'm trying to show here that MQ model is very problematic, and won't work well *even if UA has perfectly accurate bandwidth information at all times*! MQs are stateless and expected to match the same way globally, and that clashes with stateful and non-uniform nature of caches that should be taken into account. So please specifically address cases I've listed in my previous email. -- regards, Kornel On 18 maj 2012, at 10:52, Matthew Wilcox wrote: > Thanks for all the feedback everyone. > > I don't think it's going to stop people trying to do this though; > there are already write-ups for doing bandwidth detection in JS to > manipulate assets: > http://www.csskarma.com/blog/detecting-for-bandwidth/ > > Tricky problem. >> I'm not sure if that was intended to be an answer to my message: >> http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2012-May/036005.html >> >> I don't think that's at "decision" stage, because nobody has defined what >> options are there to decide. >> >> The options I see are not compelling: >> >> 1. let it match actual bandwidth and apply rules according to standard media >> query logic.

Unfortunately, I was not able to join a WG as a private "invited expert" and a different one as a Google representative (in my role as a Google contractor).
