Web browser: --- Bug ID: 55477 Summary: MultimediaViewer should support hi-DPI ('Retina') displays Product: MediaWiki extensions Version: unspecified Hardware: All OS: All Status: NEW Severity: enhancement Priority: Unprioritized Component: MultimediaViewer Assignee: wikibugs-l@lists.wikimedia.org Reporter: br...@wikimedia.org CC: fflo...@wikimedia.org, mtrac...@member.fsf.org Blocks: 32101 Classification: Unclassified Mobile Platform: --- (Jotting down some issues noted while testing, things that aren't directly related to the commits.) Currently the viewer doesn't have any handling for high-DPI/Retina displays -- the image loaded will be sized for 1x density only, and may appear blurry on sharper displays. Simplest way to handle this in near future would be something like: * get the display density with $.devicePixelRatio() -- this will return a number like 1, 1.5, 2, or another number depending on the display density and/or browser zoom level. (This is a polyfill for the window.devicePixelRatio property which adds support for IE; don't forget to include the 'jquery.hidpi' module in your dependencies if using it.) * multiply the target width and height by that ratio and round off to ints; pass that pixel size into the imageinfo request when asking for a thumbnail. * don't forget to use the _non-multiplied_ sizes in width/height attributes on the <img> -- You are receiving this mail because: You are the assignee for the bug.
