13687 2011-08-05 19:06:26 +0000 Add "exposes a bitmap" concept to image/video/canvas for CSS 2012-07-18 18:41:31 +0000 1 1 1 Unclassified WHATWG HTML unspecified PC Linux RESOLVED FIXED P2 normal Unsorted 1 jackalmage ian eoconnor ian mike contributor oldest_to_newest 54259 0 jackalmage 2011-08-05 19:06:26 +0000 See discussion starting at <http://krijnhoetmer.nl/irc-logs/whatwg/20110805#l-1054>. For the element() function defined at <http://dev.w3.org/csswg/css3-images/#element-reference>, I'm defining "exposes a bitmap" as a hook for host languages to allow elements to be referenced even when they're not actively being rendered. HTML should define that <img>, <video>, and <canvas> "expose a bitmap" in the obvious way. (Link to the concept definition will follow.) 54389 1 jackalmage 2011-08-08 19:27:17 +0000 Reference is at <http://dev.w3.org/csswg/css3-images/#paint-source>. The hook is now called "represents a paint source", and you just have to specify the width, height, and appearance of the element when in this situation. (This unifies img/video/canvas with the SVG paint servers.) 54426 2 jackalmage 2011-08-09 00:28:22 +0000 Ah, additional detail. <img> elements (and maybe <video>?) should only represent a paint source when they're loaded with a valid image. That is, an out-of-document <img> should not render its alt text (because that depends on rendering details like font-family and such). 55632 3 ian 2011-08-22 23:42:14 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
