For the particular case you link to, it's a 316dpi screen meant to be held at reading distance (slightly bent arms, etc). 15in is a good estimate for the distance, I believe, but correct me if I'm wrong. Computer screens are normally a bit further away than that, typically; figure 25 inches. So a CSS px (which is an angle subtended by 1/96 in at computer screen distance) is about (1/96 in)/(25in). A device pixel on this device subtends an angle of (1/316 in)/(15in). So a CSS pixel is 316*15/(96*25) = 1.975 device pixels on this device, and should probably be rendered as two device pixels. > Anyone from representative groups (Mozilla, Chrome Team, Apple) want to > comment? Does the spec need to be changed? I assume you've read the thread starting at http://lists.w3.org/Archives/Public/www-style/2010Jan/0058.html and especially http://lists.w3.org/Archives/Public/www-style/2010Jan/0343.html ? I believe that last is more or less Mozilla's official position, and is what we aim to implement last I checked (we support "truemm" as "mozmm" for now, pending standardization). -BorisReceived on Wednesday, 5 October 2011 16:01:46 UTC
