|
| -`iron-image` is an element for displaying an image that provides useful sizing and
|
| -preloading options not found on the standard `<img>` tag.
|
| -
|
| -The `sizing` option allows the image to be either cropped (`cover`) or
|
| -letterboxed (`contain`) to fill a fixed user-size placed on the element.
|
| -
|
| -The `preload` option prevents the browser from rendering the image until the
|
| -image is fully loaded. In the interim, either the element's CSS `background-color`
|
| -can be be used as the placeholder, or the `placeholder` property can be
|
| -set to a URL (preferably a data-URI, for instant rendering) for an
|
| -placeholder image.
|
| -
|
| -The `fade` option (only valid when `preload` is set) will cause the placeholder
|
| -image/color to be faded out once the image is rendered.
|
| -
|
| -Examples:
|
| -
|
| - Basically identical to <img src="..."> tag:
|
| -
|
| - <iron-image src="http://lorempixel.com/400/400"></iron-image>
|
| -
|
| - Will letterbox the image to fit:
|
| -
|
| - <iron-image style="width:400px; height:400px;" sizing="contain"
|
| - src="http://lorempixel.com/600/400"></iron-image>
|
| -
|
| - Will crop the image to fit:
|
| -
|
| - <iron-image style="width:400px; height:400px;" sizing="cover"
|
| - src="http://lorempixel.com/600/400"></iron-image>
|
| -
|
| - Will show light-gray background until the image loads:
|
| -
|
| - <iron-image style="width:400px; height:400px; background-color: lightgray;"
|
| - sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
|
| -
|
| - Will show a base-64 encoded placeholder image until the image loads:
|
| -
|
| - <iron-image style="width:400px; height:400px;" placeholder="data:image/gif;base64,..."
|
| - sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
|
| -
|
| - Will fade the light-gray background out once the image is loaded:
|
| -
|
| - <iron-image style="width:400px; height:400px; background-color: lightgray;"
|
| - sizing="cover" preload fade src="http://lorempixel.com/600/400"></iron-image>
