respimage

Version:

The fast, lightweight and reliable polyfill for responsive images (i.e. picture element and the srcset, sizes and media attributes). With a smart resource selection algorithm, that saves bandwidth.

# CHANGELOG ###1.4.0/1.4.1 * renamed ``reparse`` option to ``reevaluate`` (better compatibility with picturefill) * Changed candidate selection for more quality especially on lower resolution devices * added video/vnd.mozilla.apng and video/x-apng types for apng in typesupport plugin (only 1.4.1) ###1.3.1 * fix intrinsic dimension plugin in IE11 in conjunction with SVG images * allow complex combined media conditions in ``sizes`` attribute ###1.2.1 * fixes intrinsic sizes plugin sometimes disconnects MutationObserver * improve media attribute order in conjunction with type attribute * use lqip pattern also in browsers, which support image abortion (improves speedindex) * improve mutation performance for browsers without MuationObserver support * be more memory efficient ###1.2.0 * improved performance for upcoming FF 36+ * decoupled intrinsic sizing from resource selection (makes [intrinsic size plugin smoother](http://jsfiddle.net/trixta/gs3p14pr/embedded/result/)) * added SEO pattern * improved documentation * changed config options * simplified and improved smart source selection * modification to the lqip pattern. The time to the onload event is now more often increased, but perceived performance is much better. ###1.1.6 * changed viewport calculation for IE8 to correspond to respondjs * added experimental print extension plugin ###1.1.5 * improved viewport width/height detection ###1.1.4 * improved intrinsic sizes plugin * improved ``currentSrc`` property and moved it to the [mutation plugin](plugins/mutation). * refinements to the source selection algorithm. compared to previous version: * smart source selection runs less aggressive on 1x devices (better for quality). * smart source selection runs more aggressive on 2x+ devices (better for performance). * smart source selection runs less aggressive in portrait mode than in landscape mode (good for orientation change). * implemented orientation media query polyfill (mainly for IE8 but also IE9). * implemented ``srcset`` and ``src`` getter/setters into mutation plugin. * removed perfselection plugin. (Non-biased part is now directly included into the main script. For the "biased" part [use some other x-browser techniques](plugins/perfselection).) ###1.1.1-1.1.3 * no script changes, only adjustments to the package.json (sorry for the release noise) ###1.1.0 * improve [intrinsic scaling and move it to a plugin](plugins/intrinsic-dimension) * allow use of h descriptor (allow futureproof markup) * make respimage lazier on resize * improve image abortion for trident * tests tests tests ;-) ###1.0.0 * CSS calc function in the ``sizes`` attribute in conjunction with em/vw is now 100% precise and works even in IE8 * massive network performance improvement for the Trident engine (IE) if a ``src`` fallback attribute is specified ###0.9.6 * improve addSize option ###0.9.5 * improve memory usage * add type support plugin * fixed debug message (for source and size order) + added new debug messages ### 0.9.4 * handle changes to devicePixelRatio * improve debugging information in *.dev.js (Test wether calculated sizes matches rendered size of image + Test order of source elements and sizes attribute) * Stick to editorconfig in all files * removed UMD (simply not so good for polyfills, sorry) * Add `.editorconfig` file to ensure coding conventions * Update npm dependencies * add ``lazyload`` check ### v0.9.3-RC1 ### v0.9.3 ### v0.9.2 ### v0.9.1 ### v0.9.0-RC2 ### v0.9.0
