|
| +`<ripple-animation>` scales and transform an element such that it appears to ripple from either
|
| +a shared element, or from a screen position, to full screen.
|
| +
|
| +If using as a shared element animation in `<neon-animated-pages>`, use this animation in an `exit`
|
| +animation in the source page and in an `entry` animation in the destination page. Also, define the
|
| +hero elements in the `sharedElements` property (not a configuration property, see
|
| +`Polymer.NeonSharedElementAnimatableBehavior`).
|
| +
|
| +If using a screen position, define the `gesture` property.
|
| +
|
| +Configuration:
|
| +```
|
| +{
|
| + name: 'ripple-animation`.
|
| + id: <shared-element-id>, /* set this or gesture */
|
| + gesture: {x: <page-x>, y: <page-y>}, /* set this or id */
|
| + timing: <animation-timing>,
|
| + toPage: <node>, /* define for the destination page */
|
| + fromPage: <node>, /* define for the source page */
|
| +}
