(A May version of the draft had this backwards and the current version is not clear; probably because the rendering section is not done yet.) 21156 1 ian 2008-07-11 19:59:19 +0000 Yeah, it should return 0 when there's no image, and the intrinsic width if the image isn't rendered. 21326 2 olivier.gendrin 2008-07-25 07:56:06 +0000 Ian : what do you call 'no image' : an empty source, or an 404 HTTP request ? And is 'intrinsic image height/width' overriden by @width and @height img attributes ? 21327 3 ian 2008-07-25 09:36:04 +0000 Does the text in the spec now answer those questions? 21332 4 olivier.gendrin 2008-07-25 12:09:19 +0000 Ian, if you mean http://dev.w3.org/cvsweb/~checkout~/html5/spec/Overview.html?rev=1.1128#dimension0, the last sentence miss the img tag ("The width and height DOM attributes on the embed, object, and video elements must reflect the content attributes of the same name."). And if the img is missing, yes, it answers my question, thanks. 21339 5 ian 2008-07-25 18:23:02 +0000 Well I don't only mean that section, I also mean the bits that define HTMLImageElement.height and .width, the height/width content attributes, fetching, and so forth. 21352 6 olivier.gendrin 2008-07-28 10:14:16 +0000 You mean "The DOM attributes width and height must return the rendered width and height of the image, in CSS pixels, if the image is being rendered, and is being rendered to a visual medium; or else the intrinsic with and height of the image, in CSS pixels, if the image is available but not being rendered to a visual medium; or else 0, if the image is not available or its dimensions are not known." ? (I think that the last 'or', "if the image is not available or its dimensions are not known.", should be an 'and'.) 21359 7 ian 2008-07-28 19:42:33 +0000 So what should it return if the image is available but it's dimensions are not known? (e.g. it has no intrinsic dimensions, like a dynamically sized gradient or infinite pattern) 21362 8 olivier.gendrin 2008-07-29 08:02:05 +0000 Ok, would never have though to so strange 'images'...
